.net has all these build in GUI elements. The purpose is that we build a .net web application and for the coding itselve I'm very familiar with jQuery in PHP but I noticed that in .Net everybody starts using it too.Is jQuery the best way these days to deal with this in .NET (c#)? or are there others you might recommend?
View 5 RepliesBasically I have a page where a user can select up to 3 vehicles by make and model. I have 3 divs on the page that is generated with a basic foreach loop. When the user selects a make and model from respective dropdown lists I am firing a javascript function that returns a JSonResult that loads a dynamic partial view into a seperate div. This partial view displays a div with a grid whereby the user can select one of n-number of services using a checkbox.Next what I would like to do is if the user selects a servce for the one of the vehicle selections, I would like to add this selection to a list of "ServiceSelection" that is part of my viewmodel. Ultimately the user would click a button that would redirect to the next step in the process and pass the entire updated viewmodel to this new page.

I would love to create a "daemon" which in specified time intervals will move-transfer any zip files uploaded by the users from a.example.com to b.example.com
From the info i gathered so far,
The daemon will be an .ashx generic handler. The daemon will be triggered at the specified time intervals via a plesk cron job The daemon (thanks to SLaks) will consist of two FtpWebRequest's (One for reading and one for writing).
So the question is how could i implement step 3?
Do i have to read into to a memory() array the whole file and try to write that in b.example.com ? How could i write the info i read to b.example.com? Could i perform reading and writing of the file at the same time?
No i am not asking for the full code, i just can figure out, how could i perform reading and writing on the fly, without user interaction.
I mean i could download the file locally from a.example.com and upload it at b.example.com but that is not the point.
I am working with asp.net 2.0 and sql server 2005. so trying to describe it below:
THE SITUATION
I have a few tables to hold data for billing information. The first table has each dedicated to each location, and a serial number that can be incremented. The concept is to update this data based on location, every time there is a new bill, so may be location A has serial 25 since it is doing well but location B has serial 5.
THE PROBLEM
SO based on this requirement I need to update a table to get the latest serial for a particular location and then use that serial for other tables which will be holding the billing details. The second part is as regular as it can be, but generating a new number, and getting this value is my problem. Since this will be multi user system, so I want some robust solution. I do not know whether I can use a identity field for this purpose or not.
I have to choose between Server.transfer and Response.redirect for an Intranet application for navigation. I have chosen Server.Transfer as of now because it avoid extra round trip to server and which will help when so many users will be accessing the application. (I believe this is the main difference between reponse.redirect and server.transfer). But the problem is now that URL won't change on Server.Transfer(I don't want to implement Http headerS, as I am afraid it will take time to implement that).on redirection, I want to do something like taking benefit of server.redirect(in avoiding server processing, which happens in response.redirect) and changing the URL(as it happens in reponse.redirect).Can anyone please suggest a quick solution to it or may be help me Telling How many users can reponse.redirect can support ?
View 11 RepliesFollowed the code sample of Chapter 10 (Logging in) of the Book, Microsoft ASP.NET 2.0, I created an ASP.NET 3.5 website with Forms Authentication. The sample code used Website Administration Tool (WAT) to manage the users, roles, and authorization.When running in the ASP.NET Development server environment, I can first login, then click to open the links for each for the 3 roles.
However when running the sample code in the IIS server environment, I can login but can not open the links for the role subfolders.Clicking each link popped up an error message for opening a login.aspx from the specific subfolder. I don't have a Login.aspx file in each subfolder.The 3 role subfolders were configured as the virtual folders in the IIS Server. Why the sample code worked fine inASP.NET Development server environment, but got an error message from theIIS Server environment? Why an authenticated user can not open the subfolder homepage?
I have a block of XML in a database which is easy enough to pull out using ASP.NET MVC, however I would like to access and modify the XML in an way more consistent with class instances. Is there a way to get the MVC (or any other model) to generate a data access (or perhaps Entity) class set from the DB-stored XML?If the above is rather obtuse, the question could be summarised as; What method would you use to best access and modify XML stored in a database from an ASP.NET MVC application?
View 1 RepliesIm currently starting on a project where im using NHibernate for dealing with the DB interactions, and MVC2 (RC) for the front end... and im just wondering if there are any decent tutorials on how to minimize the amount of duplicated validation that needs to be entered to validate thigns in NHibernate and try to mirror those constraints client side.. Ive looked at xVal which looks great, but i cant seem to get it to work and there dont seem to be that many articles about it. Also alot of people are mentioning that its going to become redundant at the MVC level in MVC2 due to the data annotation validation. So im really just after some more information/advice and links on the subject really...

View 8 Replies I have the following scheme: a View (comming from an action method) called EventSearch that contains a DropDownList of PowerPlants, a ListBox with GeneratingUnits, a DropDownList and two TextFields to set the timespan (you can choose a predefined timespan in the DropDownList or set your own in the TextFields). The model for this page is a DataQuery (an object to be tested against the Database to search the matching values). Clicking in a button in this View will cause a POST.
Then, in another View, called EventList, with the Model being List, I render the above Action, so the user can trigger a search in the same page he visualizes the results.Usually, the number of itens in the list to be displayed in EventList is massive, so I wanted to give paging a try:
[Code]....
when I try sorting or even change page, the results don't get displayed. Here is my ActionMethods for EventList:

I don't know if it doesn't work by the way I created the pages (using this DataQuery object) and if there is another way out of this problem.
I built a scraper for an ASP.NET site (specifically a Jenzabar course searching portlet) that would create a new session, load the first search page, then simulate a search by posting back the required fields. However, something changed, and I can't figure out what, and now I get HTTP 500 responses to everything. There are no new fields in the browser's POST data that I can see.I would ideally like to figure out how to fix my own scraper, but that is probably difficult to ask about on StackOverflow without including a ton of specific contex

I'm using the standard asp:Login control, and we have a user who recently changed her password to include an angular bracket. When she tries to login, she gets an error message, and I get the standard 'dangerous request' exception.
I know I can set ValidateRequest="false" on the page to negate this, but I was hoping someone knew of a better way.
In my new ASP.NET EF4 project, I find myself having to do a lot of maneuvering around null entities. For example, I may have a Project Entity with a related User Entity exposed through an Assignee property. Suppose I need to send an email to someone indicating who the Assignee is, I need to say:string x = "The Assignee is: " + TheProject.Assignee.Name;but I'll get an exception if there is no Assignee as the property is null (I want nulls by design) and I can't fetch the .Name property on that null.
View 4 RepliesWe are using cutesoft AJAX uploader. The uplodaer is implemented using HTTP Modules. Everything works well. The problem is that if the user clicks the upload button after being idle for long (means after session time out) the control throws and error.
I just want to know the work around to bypass this issue.
Note:- We are just using one web.config and two master pages (one for login and error pages and one for all other pages which are accessed after authentication). We have written the code to check the session timeout in oninit of the master page which is used by all the pages except (Login and Error pages).
I am planning to convert desktop application which has to deal with lots of client resources like printer, Id scanner(driver license,passport & business card etc.), webcam etc.Now accessing client resources like files, scanners and webcam everything has to be done through client side scripting which is really pain. Due to nature of this product, I have to create image on client PC and extract information from it. (This is also pain in Vista and Windows 7 due to security permissions and all that stuff).
My ideal design would be making managed dll which takes care of dealing with images, printers, webcam (I have to apply pan, tilt and zoom), id-scanners. This is kind of component. And GUI would be web based Asp.net which simply calls the functions of managed dll. If the end-user is opening application on new computer, then it will ask just like flash or silverlight that you have to install component locally for the first time.Points which I worry: 1. If it logically correct or sounds stupid? 2. How to install managed dll at end-user's PC (C:/program files) and use it from asp.net code behind page.
My application is intranet application.so avoid stupid assumptions about privacy and ohhooo you want to access files from my PC and all those stuff. (end-user would never mind in giving credit card to restaurnt waiter who could do anything with it behind counter but allowing web application to access file which is created by application is privacy issue)

I read some article about unitOfwork and repository but i'm still confused about how they interact, and how to use them in the right way.
I'm using an addressbook project to practise on patterns (even if , likely, patterns are not usefull) without any ORM framework for persistence.
My domain objects are (at now) : AddressBook (acts as an application controller), Contact (contains information about each contact in the address book), ContactGroup (mantain collections of contact).
Should i have to use distinct repository object for contact ad contactgroup?
I thought to use a UnitOfWork for the operation about the adding/removing contact to group : the user can add existing contact to a group, create a new contact while adding it to the group or remove contact from group.
I used SQLMetal to generate a DBML file, which worked fine. The problem is that since this DBML file is so big (185,000 lines at 840Kb) it takes literally hours to load in VS2008. What is the recommended way to resolve this? I tried using a third party tool call SqlMetalInclude to break the DBML up into multiple data contexts, but that tool generates only designer.cs files, not dbml files.
View 2 RepliesLearning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008
CSS sample:
body
{
height:1200px;
width:920px;
border-style:solid;
border-color:blue;
padding:10px 10px 10px 10px;
}
#toptext1
{
position:relative;
top:-225px;
right:-500px;
font-size:22px;
font-weight:bold;
}
From the master page:
<body>
<form id="form1" runat="server">
<asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server"
AlternateText="CookNook" Width="449px"></asp:image>
<p>
<asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label>
</p>
From the content page:
<%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" />
</asp:Content>
When I was doing this without a master page it worked so where am I going wrong with the attributes?
I have several ASP.NET sites, hosted on the same domain (different subdomains) and working via HTTPS. I have WCF service, hosted on the same domain. I have a separate state server for sessions.
All sites use cookieless session (if someone asks why - i will reply later, but it's a 'must')
On my sites, I use grid components from Telerik (but actually it does not matter) that ask for data from WCF service and must be filled with this data.
The problems are:
1) I cannot manage to make POST request to WCF service from javascript: for some reason it's always either GET or OPTIONS (no matter if I use Sys.Net.WebServiceProxy invoke or just a plain jquery AJAX request). It happens even if I indicate COOKIE mode, not cookieless. Maybe because of this I am getting "405 Method not allowed" error - WCF is set for POST request, but the site sends GET...
2) I cannot manage to retrieve SESSION from my websites! I tried approach, that I found, but WCF always uses OWN session, instead of 'connecting' to existing ASP.NET session, despite on ASP.NET compatibility mode. I need SESSION to exchange data between my sites and WCF service
3) I don't have idea currently, how to manage security when exchanging data between mentioned ones, in the light of above-mentioned problems...
4) I don't know exactly, how web.config for WCF service should look like in my case, because I've seen tons of different variants, but all for some simple cases.
Would be really appreciated for the help! I'm stuck for 2 or 3 weeks already, far behind the plan, but nothing still works... I can see there are some pieces of info about similar problems, but I'm afraid to miss some small thing - in web.config or method attribute or IIS setting, etc - and f... up everything.
