Asp onrowupdating not working
Editing the Grid View control can be an incredibly easy feature to add for certain database tables, especially those who have no foreign key associated and can easily be edited through the use of a standard Text Box web control as shown in the figure below: 1.You need to include the Grid View Command Field column to add Edit, Update and Cancel Buttons in the Grid View. You need to include Template Field for every column you want to provide Editing because Template Field provides you both Item Template and Edit Item Template to create interface for two separate Grid View modes. You need to handle Grid View events such as Row Editing, Row Canceling Edit and Row Updating to provide desired editing functionality.Font-Names="Verdana" Font-Size="10" Data Key Names="Product ID" Auto Generate Columns="false" onrowcancelingedit="Grid View1_Row Canceling Edit" onrowediting="Grid View1_Row Editing" onrowupdating="Grid View1_Row Updating"In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.

Hi All I am creating a Datagrid on the fly, which works fine, added a edit,cancel update command field as a template field.Row Updating event, doesn’t work as all samples say it should do.All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.
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.
But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.
When I hit Update, the changes are not saved, and there is no error message. When I hit Update, the changes are not saved, and there is no error message. 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 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.
