Rowupdating in gridview in vb net
In this article I will share how to retrieve hidden value from Grid View Column. I had a assignment I need to show only description and not ID. By using Datakeynames property you will get the selected row primary key. I put a breakpoint on the Row Updating event handler and found that the event is not fired. I put a breakpoint on the Row Updating event handler and found that the event is not fired. In the Row Editing function, the edit textboxes appear and I can get the "old" values Then the page renders, I edit the textboxes and hit Update.
Thus, in order to switch it into Edit Mode, in each of your event handles (Row Editing, Row Updating, and Row Canceling Edit) you must do two things: Protected Sub Grid View1_Row Editing(By Val sender As System.
Edit Index = -1 'set to no selection Bind Grid View() End Sub One issue I ran into while attempting to figure this all out was if I didn’t rebind my Grid View at the end of each event, I was required to click twice to get it to select the correct row, and if I clicked around, it would always be a row behind. This blog is for nothing else than to try and help me help you and help you help me and us help everyone else try to fix anything and everything we can’t figure out with this language.
Do you have some sort of Java Script functionality that may be stopping it? A common problem people have with Grid Views is understanding when to data bind the data source to the Grid View.
-Frinny Hi all, I seem to be having the same issue but I don't quite follow the trouble with the above post. Can you explain the T/S a little more or maybe point me to another post that may have already covered it? Hi all, I seem to be having the same issue but I don't quite follow the trouble with the above post.

It's quite common that people create the data source and bind this source to the Grid View in their Page_Load() method.
After working with Data Grids so efficiently, I was scared that Grid Views were going to be a million times more complex.
I suppose my eyes got big when I saw all the new properties and methods, and wanted to try them all out. Most articles I found were for hardcoded datasources (especially on MSDN, ugh) and didn’t really help me much, so this post will be referring to Grid Views with dynamically bound datasources. What happens with this is that the source is being created every time the user submits the page.This means that when the user does an update, the data from that update is lost. Hope this saves someone a full day of research (and possibly some hair)! To enhance this process, be sure to include your Grid View in an AJAX Update Panel.If you do this, your Grid View's source will be refreshed before you're able to grab the new values out of it.
