Rowupdating code

Rated 3.98/5 based on 515 customer reviews

As a workaround, I can add a javascript onchange event to the Drop Down List which is called when the value changes.Is there a way I can pass this value back to the server and use it?So, you could use it in the javascript onchange event.I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. I am using a SQLData Source to populate my gridview in ASP. When I hit Edit, the textboxes appear and I am able to edit my values. 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. Yes, I did put the breakpoint at the Row Updating line (and not in the function).I have a break on the Sub statement for the Row Updating handler ... The Edit and Cancel buttons fire the Row Command event, however, the Update button does not. No breakpoint was triggered when I hit the Update button. I truly appreciate all the suggestions you've given. This is becoming so frustrating it's getting almost comical. Breakpoints were triggered for the Row Editing and Row Command.

So far so good, this all works, the grid is displayed, the Drop Down List appears, filled with the correct data, shows the correct initial item and lets the user select another. The when trying to get the value from the Drop Down List in the Row Updating event, I cant find it. I create a Recursive Find Control method that ran through every control on the page, and it cant find it.Unfortunatley, I can't drop the dynamic creation, as this app is used to maintain three different systems, and being defined by an XML configuration file, means that the page can be used to maintain multiple tables.After investigation, it looks like the Selected Index Changed is not called because on the postback with update, the Drop Down List doesn't exists, therefore the event doesn't exist.This means that when the user does an update, the data from that update is lost.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.
