Asp net gridview rowupdating not firing

We will use Template Field, whenever we want to define some custom control in the data bound controls like Grid View, Data Grid or Data Repeater.

If he clicks edit (or) in the edit mode he can be able to see the Textbox.

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.

Hope this saves someone a full day of research (and possibly some hair)!

THE PROBLEM: You are going on your merry way coding a Grid View (not using a SQLData Source or anything, just the database flavor of the day) and you can't get that update link/button to fire off any event, let alone the Row Updating event that you want to fire.

THE ANSWER: Making sure that Button Type="Link" and Causes Validation="false" appears to fix the problem.

To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.

In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.

So once after done with editing data, if we click update the following method will be triggered. Once we access the required fields in the code behind, we need to update the data in the database and show the updated data to the user. If the user clicks the Delete button On Row Deleting event will be fired. Going into that code we are trying to get the primary key of the employee table(Employee ID) by using Grid View Data Key Names and then This entry was posted on March 27, 2009 at am and is filed under ASP.

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.

First, create a Grid View with three bound columns and an Update/Edit/Cancel (Command Field) column: Nothing in there should be shocking to anyone: all your events are handled, you have a Hyper Link Field that uses the Data Navigate URLFields property to insert a Product ID, and you have set your Data Key Names property to your hidden field which holds your Product ID.

This was my first foray into this part of the Grid View’s functionality, since I haven’t really had to develop anything using it since the switch to 2.0, as everything in Data Grids still functioned fine. The Row Updating event is where it gets tricky, since pulling values is not necessarily intuitive. That’s where you come in 🙂 If you’re interested in joining the discussion to post your own problems, fixes, etc.

With a little bit of research, a lot bit of patience, and some help from the internet community, I was able to solve all my issues, and pretty elegantly at that. You can’t do something like Dim name As Hyper Link Dim inv As Text Box name = CType(Grid View1. in an actual post, just email me or comment somewhere and we’ll talk about it.
