Run web control code before the parent page code

jrmcintosh asked
Last Modified: 2008-04-24
I have a web control within a page that has multiple datagrids in it. Within these data grids is a button column that allows users to delete data. When I click on this button column it does not go directly to the call I have to delete the data but rather refreshes the parent page. How do I force it to run the web control code first?


Private Sub dgage_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgage.ItemCommand

        If e.CommandName = "DeleteRec" Then
                'Delete metric and reload dgs

                Dim db As Database = DatabaseFactory.CreateDatabase()
                Dim cmd As DBCommandWrapper
                Dim sqlCommand As String
                sqlCommand = "usp_del_metric"
                cmd = db.GetStoredProcCommandWrapper(sqlCommand)
                cmd.AddInParameter("@rec_id", DbType.String, e.Item.Cells(3).Text)
                cmd.AddOutParameter("@metcount", DbType.Int32, 8)


            Catch err As Exception
                Dim log As New Framework.Logging(err.GetType.ToString(), err.Source, err.Message, err.StackTrace, Environment.MachineName)
            End Try
        End If
    End Sub

Let's see if I understand.

You click on a button in a DataGrid, and the page posts back.  You want to do the code immediately.  

If that is true, it is not going to happen server-side, it would have to happen client-side with Javascript or AJAX calls.

This one is on us!

oops, somehow accidentally clicked submit :)

and then, you can write code in your event handlers, and the normal page_load code won't execute when you 'post back'....like in your 'dgage_ItemCommand'.

where you can delete the data, and then bind the data again afterwards
