I am trying to code (.net) in the autosave functionality without clogging the network. I am trying to capture data from a webpage into a file on the local drive and automate save every 5 mins. Then finally when the user hits "save" the data should be pulled from the local file to update the data base.
View 1 RepliesI have a form where the user enters their first name, last name, email address etc.. and then they also have the ability to enter 'cottages' that they are interested in viewing (ie. The cottage name, cottage address). The user then needs to be able to 'save' this somewhere and enter another cottage into the same form.
Finally the user will submit the form, and all the user details, and cottage details will be emailed to admin.
I was attempting to use a gridview, but found that it was a little to restrictive in terms of formatting. So I'm using a DataReader and a StringBuilder (using the Append method to attach to the Literal control) to build a form. The form is pretty simple: labels, radio buttons, and textboxes. The appended data was practically taken from a classic asp page (with just some minor tweeking). For the most part there will always be 5 records on the form to loop through and save (sometimes less...never more).
Now comes the tricky part. I want to save the information on my form, but I'm not sure how to proceed. Do I use the Append method to add a save button to my form. And if so, how do I save the data (I couldn't use the codebehind could I)? Do I use an asp:Button and if so, will it recognize the form since it was build dynammically?
I have a large multi-step form that will insert a record into a database. I'm using ASP.NET and I know there are some pre-made controls you can use for this, but I'm not all that familiar with all of them. The formview seems to be a good control, but I'm not sure if it could be used with multiple steps/pages...? What's the best way to do this?
View 1 RepliesI'm using ASP.NET MVC 2 and am struggling with saving child entities. I have an existing Invoice entity (which I create on a separate form) and then I have a LogHours view that I'd like to use to save InvoiceLog's, which are child entities of Invoice. Here's the view:
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TothSolutions.Data.Invoice>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Log Hours
</asp:Content>.......
In the SaveHours action, it properly sets the values of the InvoiceLog entities after I call TryUpdateModel but when it does SaveChanges it doesn't update the database with the new values. Also, if you manually update the values of the InvoiceLog entries in the database and then go to this page it doesn't populate the textboxes so it's clearly not binding correctly.
This works in other browsers but not in chrome. I am trying to allow users to upload large files and have an ajax call to update them on the progress of the file upload.
So a unique ID is generated on the client side and added to the action of the form before sending. Then the form is submitted (form only contains a file upload input) and an ajax call is made to get the progress of the upload. The ajax call goes to another page and uses the ID to lookup the upload.
I am using JQuery 1.5.1. Debugging this and putting something on the error function give me nothing other than "error". Not very helpful. I used Chrome's debugger and it just says failed to load resource xxxx.aspx. xxx.aspx is the URL i needed. Turns out that there seems to be some sort of conflict between the form and the ajax call.
I am using a from view for data entry. I need to verify that a check box is true or false after editing a record.
I have been accessing label text using the following|
CType(FormView1.FindControl("RespDeptLabel"), Label).Text
How can I access the state of a checkbox in the form view to determine if it is true or false
we have a classic ASP Webpage for displaying reporting data.
The process is following:
user inputs reporting criteria reporting criteria are passed to a method in a VB6 DLL containing the reporting business logic (generating a dynmic sql statement) VB6 DLL method returns xml data xml data are displayed with xsd transformation 150.000 datarows are displayed in some seconds (less than 10 seconds maybe) Now we want to extend this reporting function and decided to use asp.net (2.0) So I have written a little prototyp application with a SqlDataSource Object and a GridView Control.
A table with less data (about 100 or so) are displayed quickly.
But a view with about 150.000 datarows needs about 2 minutes and ended with a OutOfMemoryException!
The request of the customer is definitvely to display the data on one page like in the old classic asp application!
I have a datagrid in aspx page.Inside of datagrid i am using around 15 controls such as Button,dropdownlist and text box

I have a drop down list . In that list i have to show more then 3000 value comes form SQL Server database
Becasuse of huge amount of data the drop-down list preforms slowly.... is there any way so that the dropdownlist performs faster.
i have this code in Page_Load()

I have a query string with huge params (greater than 2 KB) and i have to pass it to another page in which there is an email component. I have to send the email with a link (URL) that has the query string so that user can click on the link and access the page.
View 4 RepliesI have a gridview that is currently showing 20 lines per page. Each line has several fields in it, three of which are dropdownlists. These dropdownlists are populated with a SQLDataSource and then the selected value is bound to one of the gridview datalements.
The problem I'm running into is that the page is very slow to load. I believe this is because of the large dropdownlists (and possibly because there are roughly 60 of them, each of which is executing a SQL query to populate the list of available values). The file size that is being transmitted over the web is just over 1.25MB in size, again from the large amounts of data in the dropdownlists.
Is anyone aware of a technique by which I could only execute the query from the SQLDataSources that populate the dropdownlists' available values once and then reuse the results of that query to populate the relevant dropdowns? Ideally I would do this on the client side so it would also limit the amount of text being transmitted to the client browser.
I have Master Page and ascx user controls in my application.
how would I use the Cross-Page technique using the @ PreviousPageType directive.
useful links or samples to achieve this.
I am trying to use the Page class that exposes a property named PreviousPage from my User Control.
I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.
The website I am working on has a section where users can search for content they have digitally subscribed to. way to cross-check both data sets, the first being content that matches the search criteria, the second being the content the user has subscribed to. What's making this is a mess is how the data is structured. Here is an example...
We store all of our content in a "Content" table in our database. A piece of content, a "journal", for example, and all of its child records (volumes, issues, and articles) are all stored as records in the "Content" table, each with a ParentId of its corresponding parent record. So, A journal can have n volumes. Each volume can have n issues. Each issue can have n articles. A user can have a subscription to any of these, which would implicitly give them access to all child records. For example, if a user was subscribed to a journal, they would have access to all of its volumes, issues, and articles. If the user was subscribed to an issue, they would have access to all of its articles, but not the parent volume or journal.
Some users own over 30,000 records, and we have over 100,000 content records in the database. The Content table has relationships with several other tables that are used for the search. This leaves me with an expensive query to find what the user has access to, and another expensive query to search through all of the records to find search criteria matches. Some of our searches take 20-30 seconds and I would like to speed it up to a max of 5sec per search.
I tried running a query to get the ContentIds of everything the user owned when they first visited the search page, and then caching it to eliminate further database hits, but when I passed the list of ints into the query via a linq .Contains statement, I hit the SQL parameter limit of 2100, since apparently .Contains() splits them all out.
when i did not have too many controls on the gridview, it was displaying fine. but when i added more controls, it has become very slow and displays a large size for a second or so, and then comes to normal size.
View 1 RepliesASP.NET 3.5,I'm upgrading a page that currently uses classic asp and xslt to display about 2000 readonly tabular records. Please leave aside the issue of whether this is a good idea or not.My asp.net replacement page uses a gridview to do the same thing.The scrolling in IE8 using this old code is very smooth and even. The scrolling using the asp.net page is horribly jerky. I can't figure out why - there doesn't appear to be much client side code running.Any clues welcome as this is a high traffic page that I want to look as good as possible.The same page also can't handle a row highlighter - same reason slow and jerky.
View 2 RepliesI am having nearly more than 80 thousand records and i need to export in .csv format.
I need to export to woksheet.
I need to export nearly 65 thousands of records in one sheet,
When it reached the limit, it should exported in the next sheet.
if i want to get multiple values from database and pass this dataset to another page can we use session to store the dataset values..i knw we can..but some one says that its not a gud approach..this will cause server process down..is it true?if it so then wat are all the other ways to do that?
View 1 RepliesI would like to save some data for use after a page postback. Here is an example of what I'd like to do:
Partial Class TestPage
Inherits System.Web.UI.Page
Private _CategoryID As String = ""
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
_CategoryID = "ABC"
Me.ViewState("CategoryID") = _CategoryID
Else
_CategoryID = CType(Me.ViewState("CategoryID"), String)
End If
End Sub
End Class
I've tried both session variables and view state. The page loads fine initially, but on postback I get the following error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
What am I doing wrong? How can I save this data for use after postback?
Using the Interop for Excel 2003 I had a nice little link that saved or opened the repeater content as .xls. Now we are using Excel 2007 and I get file format error messages. When I click the OK button on the error pop-up Excel closes. Does anyone out there know how to convert my code to handle the .xlsx format? I've been reading up on Interop for 2007 but none of the examples seem to work for this particular simple task. Here is my code from the "Export to Excel" button click:
Protected Sub btnExport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExport.Click
' Send HTTP headers that specify Excel filename, MIME type, and character set
Dim sTemp As String = "attachment;filename=CoverageCase" & Session("OpenCase").casekey.ToString & ".xlsx"

Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
' Create objects used to render the controls
Dim strw As New System.IO.StringWriter........
I found a thread from a couple of years ago dealing with this but there was no solution [URL]. There were a couple of tortureous work arounds but neither work for me.
I have a gridview, where I set the columns based on the columns in a datatable. I have a class that implements ITemplate, and creates a textbox template field. Everything works good, I can display my grid with the correct columns and headers. The probem comes up when I click a Save button, to save the user input. Of course the page postbacks, and I re-create the columns on PageInit. However, all the data the user entered is gone.
