In this example, I am going to retrieve values from categories table of Northwind database. Drag a Grid View into the Web Form and assign Data Key Names property with the primary key column i.e. In the gdview_Row Editing and gdview_Row Deleting event, we have used the below code to retrieve categoryid from datakey of Grid View, int catid = int.

Data Item, "stor_id")) Dim lnkbtnresult As Button = Direct Cast(e. Find Control("Button Delete"), Button) If lnkbtnresult Is Not Nothing Then lnkbtnresult.

Edit Index = -1 load Stores() End Sub Protected Sub grid View_Row Canceling Edit(By Val sender As Object, By Val e As Grid View Cancel Edit Event Args) grid View.

Open() Dim cmd As New Sql Command("delete from stores where stor_id=" stor_id, con) Dim result As Integer = cmd.

By default all the boundfields will be trasferred as Textboxes in Edit Mode.

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.
