I have a TreeView control defined with an XMLDataSouce and the data bindings are similar to the following:
[Code]....
I would like to be able to determine the specific node that has been clicked when entering the SelectedNodeChanged() event.I have the text from the control as TreeView.SelectedNode.Text but am unable to figure out how to get the TextField value.

I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.

I have a treeview control with Checkboxes, when 1 is checked/unchecked I would like to run some code, but for some reason nothing is being raised when I click on the checkbox. If this were a datagrid I'd be looking for the autopostback="true", but this control doesn't appear to have anything like that.
Code:

I'm not sure if this was necessary or not, but I added:

I'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:
[Code]....
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.

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.

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.

I've stepped through the code and verified this action. It gets to the end sub and just loops again. Also does it on the production server in IE and Chome (that's all I've tried). Here is the button definition on the actual ASP page:
[Code]....
It goes through the code, sends me an email, gets to End Sub, then loops right back to the top of the sub and goes through the whole thing again, sending me a duplicate email, then exiting normally and sending them to the About page. This is the only code in the aspx.vb besides the class def and inherits statement.

I have a two web forms with griviews that are bound to SQL through the same query in a class. Both have the same columns and footers. Both have a checkbox control in each grid row. The checkboxes on each form have OnCheckChanged event handlers that I put in the code behind. In fact, the html code is almost the same on both forms, and the OnCheckChanged code is exactly the same except for the fact that I have named them differently. AutoPostBack is true for both checkbox controls in the gridviews. One works, the other doesn't. The difference between the two is that the gridview row checkboxes that don't work are burried in a MultiView. Could that be why the codebehind event handler doesn't fire? Here is the html for the column:

Here is the html for the header of the gridview:

Here is the codebehind:

I have an asp.net 2.0 c# site.
In that site, I have a drop down list which allows the user to select from a number of forms with AutoPostBack set to true. I have a OnSelectedIndexChanged event on the dropdown which loads the correct control depending on which option is selected. See below:
[Code]....
Now, that works correctly and loads the form as expected, but the server side onclick event within each ascx control now doesn't work. Is there some problem with button events when controls are added this way? When I add the control in manually to the page it works fine.

i'm creating and adding checkbox in my code behind to a parent control.
autopost back is true, it's posting back on being checked, but i'm not sure how to capture the fact that it's checked before I recreate/add it to the parent control again.
i can search all controls and find it prior to re adding it to the parent, but it never shows checked...
i have a checkchanged event on it that never fires, thing it's a flow/view state issue, but not sure how to reslove...

I added some code to Global.asax on app start and I had to copy same project on a different machine and suddenly Global.asax file's event didn't fire. After doing lot of googling and trying many things I deleted the existing Global.asax and added a new one and then tested it. And I was surprised that it started to work again. so I would like to know what caused that previous Global.asax not to work?

I am losing User.Identity.Name unexpectedly, resulting in "out of the blue" redirects to Login.aspx.
This seems to happen randomly, often in the first few minutes after a user login.
To track this down I setup a Trace text file and append an entry to it when any page loads. I also write an entry from Session_OnStart event and Session_OnEnd event in Global.aspx. When user logs out, I call Session.Abandon, which should fire the Session_OnEnd event, and cause a log entry. However, this is not happening. It seems that Session.Abandon is not firing Session_OnEnd, inconsistent with info inhttp://msdn.microsoft.com/en-us/library/ms178583.aspx
Session_OnStart does seem to be firing as expected.

I am generating UserName based on FirstName.LastName after that I am hitting the database and checking if this username (Like AAA.BBB) exists or not if not then I am generating email address, if yes then it is thorowing error which is correct. And after this when I changed the username (Like AAA.BBBC) and hit enter or tab then again it should check the database and generate the email but it is not doing any thing means I think I am missing the cursor control or Second time TextBox_TextChanged event is not firing.

I have a user control that has an event that checks if a textbox is empty and does other processing...this event would also set a publ;ic property on the user control to a boolean value.
1) On the host page/parent, I want to click a button that will set off the event explained above.
2) Also, how do I reference the user control on the host page?

On my page, the user is basically registering for a site and I am trying to do a username availability check, without doing the javascript myself(not very good with it yet). The code that is shown below shows the contents for 1 out of 5 textboxes on the page. They all are in the same validator group that is triggered by a button. I have tested the availability query check itself and it works, but only once the submit button is clicked. Nothign is happening when I tab away from the textbox after enetering text.And this page is actually 3 tabs (not sure if there is some sort of a bug that involves tab containers possibly).
I here's the client-sdie code for the page (at least what pertains to this):

And here is the server-side:

I have a form that contains a Table control. The columns and rows are created dynamically, so there needs to be a way to maintain the state of the table. The table ALSO has textboxes within it that will fire a postback and update a database entry when the text has changed. Kind of like an excel-type configuration.
Anyways, I figured the best way to do this was to create a class object to create a standardized way of creating the Table, and then storing it in the Session. Every page reload I then readd the table to the form, so it looks like it is maintaining state.
Now, everything works fine and dandy, but my textboxes have an event handler which is stored in the class file. I can type in the textboxes and the form reposts, but the TextChanged event never fires.
Here's my code for the file:

And here is the page that utilizes it:

I'm using SelectedIndexChanged on a gridview row to trigger an event which is working fine in a normal webform. But, when I included "master page", it's not triggering the same event.
everything is same except, I added MasterPageFile location & removed FORM tag.
ASP code

I have TreeView on a Sharepoint aspx page. The tree is populated dynamically using a Sharepoint list containing a folder-stucture. I would like to handle Select-actions but I am not able to.. the SelectedNodeChanged event only seems to occur when I select the outer-most nodes. Minimal example code for the UserControl where the TreeView is located is found below.
