I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

I have built a web site for our company in 2.0 (to be upgraded to 3.5 at a later time). The landing page (default) does not use a master page, where as the back pages do use a master page. I am using a style sheet in a root folder called "styles" (all background images are loaded from the style sheet), and the images are located in a root folder called "images".Adding the preload image scripts head section in the default page is simple enough, but I am not sure about what to do in the pages that use master pages.Would it be correct to place the preload image script in the content place holder named "head" for the pages that use the master page? And if so, do I move the "body' from that master page into each indivual page?
View 2 RepliesWe have an already existing project on IIS and we want to move to Apache (windows) with mod_aspdotnet. What things could not work? If we use 3rd party DLLs? Will office components work fine (export to Excel, Word, etc). If you have any experience on this type of migration, I'd like your inputs! Also, is there another alternative to mod_aspdotnet?

View 21 RepliesI am newbie and struggling to solve some iframe problem.
I made 3 aspx (1.aspx, 2.pasx, 3.aspx) and 1.aspx has iframe.
I loaded 2.aspx on 1.aspx iframe.

View 3 RepliesI have a simple page where I am listing records from a SQL table in a GridView. All seems to work except that users could not create records. So I created a seperate page where users can add records. This is a form with fields that user fills in and click on the submit button. Code-behind VB takes care of sending the data to a SQL Stored Proc. Upon return, I am changing text of a text label on the form which display any errors that occured during the insert.
View 1 RepliesI have a aspx page in which i create reports and charts on the fly. Creation of these charts and reports takes a lot of time because of which a blank screen is shown to the user until the creation completes.
can unlink actual report and chart creation code from page load so that i can show a processing text and then show the generated chart or report once it is ready.
EDIT :-
I would want to do something like this -
on first request trigger the report or chart creation and register a call back for completion. the client can then poll the server every 2-3 seconds to check if the report creaetion is complete.

Some time ago I converted an old windows application to a web application. This web application works fine as a stand alone app. I was recently informed that my client had a new standard layout and they are using a master page. They sent me the master page.
The web application is quite basic in that it makes a number of calls to a web service to retreive a list of customer, retrieve list of products and allows customer to create an order containing products.
I did the following to get make use of master page:
Copied it to my solution Update the page directive to include the MasterPageFile attribute and set it to point to master pageAdded the relevant content areas to my page Copied my code (control declarations etc) into the relevant content areas.The application compiles correctly and renders as expected. However, it does not behave as expected.
For example, I display a list of customers in a GridView. The user can select a customer by clicking the select button that is present for each row in GridView. I do this once and select a customer the page is posted back and relevant row is selected. I select a different customer and the page it posted back but this time the selected row does not change. It is still shown as the first row i selected.
This functionality works as expected if i remove the master page attribute and content areas.
Just started using VS2010. I am not able to move controls, in the CSS styling I checked the "Change position to absolute...." and still I am not able to move controls. Some other set up I missed?
View 3 RepliesIn my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50);
After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus.
Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.
I am writing an ASP.NET custom control.In my custom control code, I find a PlaceHolder control in the page like so:this.myPlaceholder = Page.FindControl("placeholder1") as PlaceHolder Then, I render the placeholder as the output of the custom control:
protected override void Render(HtmlTextWriter output)
if (this.myPlaceholder != null)
this.myPlaceholder.RenderControl(output);
However, this causes the placeholder to be rendered in two places - in the custom control output (good) and in the original location in the page (bad).
I am building a web page that will be presenting users two dataset results from two stored procedures in sql but the data is not similar. Is it possible to present both datasets to users in one datagridview? I am unable to do a union of the data in SQL due to the fact that the results aren't similar and wanted to see if I could work around this issue with .net.
