Up till the moment I can not understand why the "SqlDataSource_NewAccount_Inserting" event of the formview's SqlDataSource is not firing!
The code inside the event handler is not executed, even the debugger does not stop on break points inside the "SqlDataSource_NewAccount_Inserting" function!

i have built an inserting interface in a GridView's Footer Template. Added Button for insert , auto generated the insertCommand in SqlDataSource. But then how to Bind the data of inserting interface to insert command of SqlDataSource ?In FooterTemplate. i have taken TextBox.GridView's RowCommand Event is handled in this way.

(all that i did , i took help from this web site's tutorial)
So,How to insert data?
I have a couple different sqldatasources on an asp.net page that all fire the same onSelecting Event Handler. The reason for this is because the same code in the event handler can be applied to all datasources (which essentially generates filters in the queries dynamically). However, now I have another datasource that can still use most of the code, but needs to be handled slightly differenty. I could do this very easily if I could reference the datasource's ID that is firing the event (which I've tried), but this doesn't seem to be possible. Here is what I initially attempted to do:
protected void sdsTable_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
SqlDataSource sds = sender as SqlDataSource;
string dsID = sds == null ? "" : sds.ID;
if (dsID == "aDataSourceID")
{
//do this
}
else
{
//do that
}
//more code
}
This didn't work because sender is of type SqlDataSourceView and trying to cast sender as SqlDataSource returns null. So, I changed it to SqlDataSourceView:
protected void sdsTable_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
SqlDataSourceView sds = sender as SqlDataSourceView;
string dsID = sds == null ? "" : sds.Name; //Tried Name property because ID isn't available
if (dsID == "aDataSourceID")
{
//do this
}
else
{
//do that
}
//more code
}
But this still doesn't work. SqlDataSourceView doesn't seem to have a property available that gives the datasourceID of the datasource that is currently firing the event. There is a SqlDataSourceView.Name property, but this is something different. Does anyone know if it is possible to get the ID of the DataSource firing the Selecting event when that event is being handled? If so, can you provide an example on how to do this?
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 RepliesI'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing

I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)

I am using a calendar extender which is an Ajax control I am selecting a date but the event is not fired.
The reason I am doing this is because I am setting an expiry date based on the date selection.

></asp:TextBox>
<asp:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" Enabled="true" TargetControlID ="start_date" WatermarkText="Start date" runat="server">
</asp:TextBoxWatermarkExtender> <asp:CalendarExtender ID="CalendarExtender1" Enabled="true" runat="server" TargetControlID ="start_date" >
</asp:CalendarExtender>
The code behind
protected void start_date_click(object sender, EventArgs e){
DateTime begindate = DateTime.Parse(start_date.Text);
exirydate.Value = Convert.ToString(begindate.AddDays(days));
}
Is my codebehind code correct. Am i not doing in a right way.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.

rowdatabound event is not firing during postback ,What to do?First time pageload I am getting result as expected. When I click checkbox ,which is in grid ,my values which are in other columns get disappeared, that means during postback.

View 6 RepliesI have a gridview,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
[Code]....
I have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender
