Rowupdating get data
New Values("brief_Descrip")) = "" Then update Description = "" Else update Description = e. To String() End If Dim update Key As Integer = row. Text If update Description = "" Or update Description = "Null" Then update Description = "Null" End If I am guessing you are Data Binding in code-behind. (Or possibly one that implements IData Source.) If so, examine the Row (use Find Control if possible) to get the Controls holding the edited values from the Cells. However, you can also examine the Cells of the Row. Cells(6), Data Control Field Cell) Dim field1Field As Bound Field = Direct Cast(field1Cell. If you use Template Fields, you should go for the Extract Values method, and extract the values from each Cell. This can be beneficial to other community members reading the thread.
When all you've got is a Hammer, Every Problem looks like a Nail. To use Find Control you would have to build a Template Field. Text = "Database was not updated for record " & row. Text ", string text " update String "." End If Catch ex As Exception Throw ex End Try Dim field1Cell As Data Control Field Cell = Direct Cast(row. You will then get a Dictionary with all values, with the field names as keys. In the Row Updating handler, you will need to extract the values like I do in my Updating handler. Template Fields are not Bound Fields, and they don't have Data Field on them. Please remember to click “Mark as Answer” on the post that helps you.
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.

Otherwise missing cells will be nulled out by the auto update operation. The dictionary consists of the new values to be set on the row's unbound cells.
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.
