In rowupdating event in
One thing to keep in mind: the solution code iterates in reverse order through the parameters collection so that parameters are replaced correctly if there are more than nine parameters; if they were processed in forward order, parameter , and so on.
Find Control, I only get unedited values, those initially displayed from database, not the actual values displayed on screen. Rows(index) Dim str Add As String = "" str Add = (CType(row.

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.

Then within the new method one can access controls within the Grid View row being edited by referencing the Row Index attribute of the Grid View’s Rows collection. Find Control("ddl Service Level List"), Drop Down List) Dim lbl Support Date As Label = CType(GVSupport Info.

So I have my Gridview with Data Source set to a Data Table on page Load event : In the Click event of the button I want to retrieve current values of the controls, as displayed on Web page after user's actions, and pass them to my sp as a comma-separated string. Is Null Or Empty(str Add) = False Then str Per Insert = str Per Insert & str Add & "," '..so on to add values to string What to do to retrieve edited values? To finish up then one has to set the Sql Data Source Update Parameters to the desired values. The syntax for doing so is: Protected Sub GVSupport Info_Row Updating(sender As Object, e As System. For example, Fill Error could occur when you can't convert data from data from a Fill Error Event Handler handles the Fill Error event.The event handler receives an argument of type Fill Error Event Args, which contains data related to this event.
