Forms Data Controls :: GridView And Get Rid Of The Datepart Completely?
Apr 5, 2010
I'm doing a time registrating website and uses VS2008 (C#) and SQL Server database.The employees should enter their date and time, if they need to edit they push edit link in the gridview and textboxes appears (in the gridview).The problem is that not only the time is in there, but also the date like this: 2010-02-14 07:00:00.If they change, let's say they erase all in that textbox and just write like this: 08:00:00 and push update, this will happend: 2010-04-05 08:00:00.Is there a way to avoid this,is there any chance to get rid of the datepart completely?In display view I set the formatting like this: {0:HH:mm},so it shows only time and not date, but when editing date appears again.I have a seperate field for the date and only want time in this field.

Two websites that are being developed by me is online in my office network. Our IT department has updated Internet Explorer and the view my websites is completely disturbed. Now we have Internet Explorer 8.0.6001.18702 In most of my pages the setting is that from top to bottom, in top there is a panel holding dropdown, textboxes and just under this panel there is another panel with gridview. When the pages load the first panel with the search controls are ok.
When i supplied search parameters then gridview resulted overlaping the above panel and it scrolls behind the above panel. When there is one record populates to gridview the whole gridview would not be seen but the count label shows one record.

I've written a desktop application using VB.NET and SQLEXPRESS. Now I am trying to deploy it to WS 2k3. But getting positive results wiht SQLE is proving difficult. Here is the connection string I am using:
connectionString = "Data Source=.SQLEXPRESS;" + "AttachDbFilename=" + DBPath + ";" + "Integrated Security=True;" + "Connect Timeout=30;" + "User Instance=True"
The problem is the results I get from the setting of 'User Instance'. Like it is, it loads a unique stance of SQLE, which is fine. But the instance just keeps eating memory. I tried limiting memory with sp_configure, but nothing happened. It just keeps growing. If I exclude 'User Instance', it uses the SQLE service running on my machine. It ignores the memory limitation, but eventually settles and stops growing.
Those results came from working on my local machine.When I put it on 2k3, I get the same results with User Instance = True; runaway memory. With User Instance = False, I start getting the 'attempt to attach an auto-named database failed' message. So now I am stuck. I would like to go with the 'User Instance = true' option, but I don't know how to deal with the runaway memory. If all else fails, I could use the =False option, but I just can't get 2k3 to allow.

I have some logging that has to be done, which are some database update or inserts.
However this logging is of no importance to the user, so I only want to process the data/logs after the page is completed for the user.
As of now, if I process the data while the page is loading, I go from 1.4 to 2.0 speed (server side time processing of code), which is quite a bit comparing it is of no use to the user.
So I want this code only executed after that the page is complete.
I've been checking out Ajax, async pages etc, but the problem is it still gets executed before the page is rendered to the client, which means the client will have to wait longer then it is not being processed.
I've been checking out Threadpool.queueBackgroundWorker, however if I get it correct, this will still be executed before the page is shown to the user, as it has to complete before the prerender.
Then I thought about creating a new thread, and do the processing there, which would not have my page waiting to complete the data/logging.
However when I have 100 or 200 users loading pages at the same time, then that would mean I would be creating 200 threads on those loads, which I doubt will be good for performance. So if I want to solve this, I would have to create my own threadpool and only assign for example a max of 40 threads to it which can process the data.
All I want to get done, are some update/inserts into database after the page is rendered and shown to the user. I don't want the logging to slow down the pageload for the users obviously. I want that logging or no logging makes no difference to the pageloadtime for the user at all.

import/export wizard in 2000 had lots of options.
I could copy databases without a care in the world. Including constraints, stored proc., AND the data, etc.
Now, with v2008, the wizard is dumbed down too much. It's a "stupid" copy function that fails on the first constraint it meets.
"Copy database.." is not an option here: it needs sysadmin on both source and destination server.
Re-adding the constraints manually is not an option either: the database is WAY too large.
I'm actually hoping there is a temporary bug in the import/export wizard. Each option (and you have THREE...) returns with a new error.
Googling, I found I am not alone:
http://itknowledgeexchange.techtarget.com/itanswers/sql-server-2008-export-data-problem/
This post is exactly my situation. Here's what his post says: (bolded key parts)
I'm trying to get used to sql server 2008 having been forced to upgrade by my isp. I need to back up my key db on a weekly remote schedule, so have been trying to use ssms to export data from my remote db to a local copy.
Firstly I created a new empty db on the local machine. Then I scripted the structure of the db on the remote machine and ran the resulting query on the local machine to copy the table structure into the new db. This gave me empty target tables to map to (see
below).
I used the export data wizard and selected my remote tables, then highlighted the tables to be copied and used the Edit Mappings option. Here I need to do two things, firstly checking'Enable Identity Insert' (because I have a unique id in most tables which is identity seeded, and I've read that if this is not checked sql server will helpfully renumber your entire table, rendering all your foreign key references useless). Secondly I need to decide what to do with the data already in the destination table. SQL 2k DTS simply dropped the destination table and recreated it. SQL 2008 will either keep the structure and delete the rows therein, or drop the table and recreate it. Because I intend to save this package and call it on a schedule in the future, I need to choose one of these options, because next time the target db won't be empty.
If I choose the delete rows option, when the package runs I get the following error when the process gets ot the first table with an identity ID which is used elsewhere in the db as a foreign key.
Error 0xc002f210: Preparation SQL Task 4: Executing the query "Truncate TABLE [dbo][tblCompany] failed with the following error 'Cannot truncate table tblCompany because it is being referenced by a foreign key constraint. Possible failure reasons: Problems with the query, "Result Set" property not set correctly, parameters not set correctly or connection not established correctly'
Half a dozen preceding tables did seem to transfer fine, but the process falls down on this one table. What I want is for the process to ignore constraints whilst it does the backup.
Undeterred I tried the other option, dropping each table and creating a new version. This time I get the error:
Error 0cx0202009: Data Flow Task 1: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code 0x80004005. An OLE DB record is available. Source MS SQL Server Native Client 10.0. Hresult 0x80004005 Description "The statement has been terminated".
An OLE DB record is available. Source MS SQL Server Native Client 10.0. Hresult 0x80004005 Description "Violation of Primary Key constraint 'PK_LoginClasses'. Cannot insert duplicate key in object 'dbo.LoginClasses'.
Then I try unchecking the Enable Identity Insert option to see what happens. This happens:
- Validating (Error)Messages
Error 0xc0202049: Data Flow Task 1: Failure inserting into the read-only column "UserID".
(SQL Server Import and Export Wizard)
Error 0xc0202045: Data Flow Task 1: Column metadata validation failed.
(SQL Server Import and Export Wizard)
Error 0xc004706b: Data Flow Task
1: "component "Destination - Login" (40)" failed validation and returned validation status "VS_ISBROKEN".
(SQL Server Import and Export Wizard)Error 0xc004700c: Data Flow Task 1: One or more component failed validation.
(SQL Server Import and Export Wizard)
Error 0xc0024107: Data Flow Task 1: There were errors during task validation.
(SQL Server Import and Export Wizard)
I can't see any more options to try. So how do I get SSMS 2008 to do what Enterprise Manager 2k did with no drama?

I have a page which includes serveral gridviews, pulling out data from my datasources. At this stage, the parameters are set withing the page, however it will use a querystring at the end of the url. Once the page is loaded, i then have an Email function calling a HTML reader, which basically captures the content of the page and pushes to the body of the email and then emails it out.
The issue i am having is where to place this stagement. I have tried to insert the email function in the Page (load complete) event, but it still seems to send out over 20 emails, which to me, means that the page hasnt finished? loading and is constantly calling the email function.
At this stage, i need this page to load .. i cant think of any other way, i can get the data sent to an email without the interim medium; the page.

I am trying to make a UserControl that have all data process, initialize data, ajax, all self contain into one control.So I can insert to anywhere on my Asp pages.But the problem is, the UserControl contains a Script Manager and the Page that contain that User Control has a Script Manager too, so Asp doesn't allow me to have two Script Manager in one page.In case like this, I wonder if UserControl can completely self contain?Or the proper way of using UserControl is just using it like a template, and all the data process, event handler I have to do on the page that contains the UserControl?

Technology: ASP.NET 4.0, C#, forms/mvc
I am a .NET web designer and I wish to create a modular based website for people, similar to what DNN does (but I want to create my own cut down version).
The idea is that I create a base website that can 'activate' features which the client needs (and has paid for). These features may be used by many clients which require frequent future updates for all clients (so I wish to keep upgrade time down to a minimum).
For example, I upload the base web application using web deploy and it sets up the core database tables/views/SPs in the process.Then I login into the website as developer and activate the out of the box features that I wish to permit the user to take advantage of. The only way I can think of currently is via user control, resources etc..But I need a little of your experience and advice over what the possibilities / dangers are....
e.g. images for an application e.g. blog, that I have activated for a client - how do I reference those images
e.g. Can user controls be dynamically added to a web application (which is pre-compiled unlike a website - it must be a web application since I am using web deploy).
e.g. Modification of web.config to add additional routing (doesn't matter if app has to go down to do this).
I can upgrade websites features en-mass, rather than manually enhancing each individual website which given a certain amount of clients would result in an awful amount of time lost.I do not have access to sharepoint (nor do I intend to). how to automate modularity completely via a front end in asp.net would be superb! how to reference files and resources outside of the websites directory and without using virtual directories

need to turn off the cookies in my ASP.net site completely
I'm doing some funky stuff serving images and scripts from a .aspx file, which causes the request to have cookies tagged to it.
So, how do I get rid of these?
I've tried setting the SessionState mode="Off" in the web.config, but that didn't seem to work.

Our current web portal at work was a port from a classic ASP codebase. Currently, all pages in our project extend a custom Page class called PortalPage. It handles login/logout, provides access to a public User object for the currently authenticated user, and adds the standard page header and footer to all of our pages. Every Page in our site is 100% designed in the codebehind. The ASPX page is not used at all. Every single div, img, and block of text is allocated as an object and added from a C# function, even if it is completely static content (which we have a decent amount of). Example for a page header:
HtmlGenericControl wrapperDiv = new HtmlGeneric("div");
HtmlAnchor bannerLink = new HtmlAnchor();
HtmlImage banner = new HtmlImage();
bannerLink.HRef = "index.aspx";
banner.Src = "mybanner.png";
banner.Alt = "My Site";
bannerLink.Controls.Add(banner);
wrapperDiv.Controls.Add(bannerLink);
this.Page.Controls.Add(wrapperDiv);
Even worse, all Javascript is added to the page as a giant mess of string concatenations:
ClientScript.RegisterClientScriptBlock(this.GetType(), "javascript", @"
<script language='javascript'>
fullUrl = '" + ConfigurationManager.AppSettings["fullUrl"].ToString() + @"';.............

I want to create a complete dynamic view engine in that absolutely all html content will be loaded from a database. This is so I have a templating engine that is totally customisable. I have something similar in classic asp and the way that works is with fillpoints so you have a master page html which will just be a string when extracted from the database and then content is dynamically added to the string to sections identified by a fill point. So for example I have my master page content loaded into a C# string and I want to load a main view and a partial view onto the page, how would you go about that in MVC? I guess I would have to keep the fill point idea as there is no other way to know where the content will go. I'm just after opinions from the community really on how to go about it.

What I have is a masterpage with some tables and contentplaceholders. What I want in some pages is that a table be removed because i have 3 columns on 3 tables and i need 2 columns only(so minus one table). Now i can access the table and give it some css through code but what i give is width:0 (and visibility:hidden if ever successful). The table contains one contentplaceholder inside a <td>. I can also access the td.The problem is that the table (thus contentplaceholder) will not go away.
It remains as entity as extending the second column will just push it downside(behavior expected when the column3 with contentplaceholder is present). So is there a way to remove the table holding the contentplaceholder?Only thought is to hide it and push it right that i admit i haven't tried it yet, I suppose it would be easier to make another master page but the problem is that i want specific designs on many pages so if this does not work i would either have to make many master pages or just use simple pages.

How to completely disable ControlState in an ASP.NET website application to get rid of <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/ACBDEFGH...XYZ=" /> on every page?
Searching for a solution, I only found meaningless answers making no difference between ControlState and ViewState, or replies saying that "we cannot disable control state". The second assumption seems to be false, since StackOverflow pages do not have ViewState hidden field.

I am trying to prevent VS from breaking on JS errors.
I have the following settings:
In IE, under Tools->Internet Settings->Advanced (tab)->Browsing
Disable script debugging (Internet Explorer) is checked.
Disable script debugging (Other) is checked.
In VS, under Debug->Exceptions->Common Language Runtime Exceptions JScript Exceptions (thrown and user-unhandled) are unchecked.
In VS, under Tools->Options->Debugging->Just-In-Time
Script is unchecked.
There are some JavaScript errors that I just don't care about and it is driving me insane having to deal with them.

I have a site that features some pages which do not require any post-back functionality. They simply display static HTML and don't even have any associated code. However, since the Master Page has a <form runat="server"> tag which wraps all ContentPlaceHolders, the resulting HTML always contains the ViewState field, i.e:
<input
type="hidden"
id="__VIEWSTATE"
value="/wEPDwUKMjEwNDQyMTMxM2Rk0XhpfvawD3g+fsmZqmeRoPnb9kI="
/>
EDIT: I tried both variants of setting EnableViewState on page level with no luck at all:
<%@ Page Language="C#" EnableViewState="false" %>
<%@ Page Language="C#" EnableViewState="true" %>
I realize, that when decrypted, this value of the input field corresponds to the <form> tag which I cannot remove because it is on my master page. However, I would still like to remove the ViewState field for pages that only display static HTML. Is it possible?

I'm doing css for a website. I send the html and css to a guy, he puts it into ASP.net. The problem is that the transfer didn't end well for my code and it needs some fixing. The problem is that when I look at it in Chrome, or Firefox, or IE8, I get three completely different renderings. I spent a good amount of time trying to fix a drop-down menu that is supposed to appear while hovering over a link. The one he had in place from ASP.net worked in IE, kinda worked in Firefox, and was completely broken in Chrome (I haven't tested Safari or Opera.) Just getting it to look basically the same in firefox and chrome was a struggle. The html source is showing me two completely different pages as well.
Does anyone have experience with this? I know nothing of ASP.net, and it seems like the guy is modifying my layout with a wsyiwyg (I found tables used in random places, which I did not put there.) Faced with this, what is my best option? Is this fixable, or am I in over my head?
