Rowupdating event in gridview in asp net
I am sharing this because I see a lot of questions on the forums on how to get the value from the Grid View object, and I know how.
As a beginner it's very tough and challenging to work with controls like a Grid View in ASP. Even I faced difficulties at the starting point of my career. Here, I am not going to explain about Grid View and other events in it, because there are a lot of good articles about that.
You should create your data source once (on the user's first visit) and store it into Session for later use, and only bind the Grid View to the data source when it is necessary to do so.
I would recommend trying this out and starting a new thread in the .
I am only going to show the different ways we can use code to take the value from Grid View.
First, we have to very be clear in our mind that there are mainly two ways of taking the cell value from the Grid View: This code is for taking the value apart from the Grid View events; that is, any common event using a sender object.
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.

It's quite common that people create the data source and bind this source to the Grid View in their Page_Load() method.
This means that when the user does an update, the data from that update is lost.
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.
Right now, I have not written code for the Update event. Right now, I have not written code for the Update event. Then the page posts back, the text boxes go back to being labels and the new values are lost, and the Row Updating code never fires.
As there are many events in Gridview But I am not conceptually aware of any event.
