In my gridview when the tab button is pressed the RowDataBound event is fired and I can capture the tab event. But if there is no data in the gridview textbox and tab is pressed, the RowDataBound event is not triggered. Is there a way to capture that event?
I am trying to capture the SelectedIndexChanged event for a drop down list I have put inside of a gridview control. It posts back fine, but does not go into my SelectedIndexChanged event handler. Here is my code

2) Make a row copy, not sure about the syntax here

I need to capture the 'Update' click event with jQuery in an asp.net GridView and have no way of knowing where to start. I'm still rather new to jQuery. My GridView is attached to a SQLDataSource and, naturally, has all the bells and whistles that that combination affords.

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).
I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.

I have a custom hierarchical data source based on the msdn example [URL] An event can be raised in the DataSourceView. If that occurs, I want to display a message on the web page.
The example is that I have a page with a TreeView control which uses a custom hierarchical datasource. If the user selects a node that they are not allowed to select, the underlying datasource will throw and error.
I want to capture this and add a message to the page. The Page_Error event is raised, but there are no eventargs.
Anybody know how to capture such an event?
An alternative approach, although not quite specific enough, is to set a flag during the datasource load event (indicating the datasource is loading) and test for this flag in the Page_Error routine.
If I replace the download.ashx with a normal aspx page, then the alert appears. So my question would be: is it possible to know programatically when the dowload.ashx returned with a response?(using FF3)
I knwo how to capture a line number from en exception error...but I have a need to capture the line number that certain things occur wihtout having excpetion thrown. I guess one way would be to force an exception to occur and then trap the line number but I dont really want to do that because that seems clumsy to me.
What woudl be nice is if there were some way to just say "what line of code is this?" programmatically.
so that regarldess of any code changes when I need that information to be grabbed it alwasy grabs the right value.
I need to achieve an effect of a read-only textbox, where when the user clicks on the textbox a popup grid control appears, after the user has made a row selection the text box is populated.... Looking at the AJAX Toolkit model it seems like a CustomExtender would be the way to go, but I can find no documentation on how to build such a thing, so I am looking at improvising.
Here is my process (which is still not working):
I have a form that contains a TextBox. A pop up window will return a value and put it into the TextBox. when this happens, i need to populate another control. I tried "OnChange" but it was not triggered .
