Gridview rowupdating oldvalues null boundaries in dating workbook ebook
I would greatly appreciate for any help or suggested ideas/approach in order to accomplish this task, or any sample codes snippet. Null Reference Exception: Object reference not set to an instance of an object...".
What is the proper coding procedures to get the old value from gridview during updating event? I tried the code snippet you've sent but i'm getting an error message: "System.
d) I set Data Member="Default View" I am not sure what am I missing.
New Values collection coming from the Grid_Row Updating Event is Empty.

Figure 1 depicts this series of events and steps when updating a Grid View.
To String = "@POrder Id" then Delete Param = param End If if param.
Data Key Names = l Keys When I removed the POrder Id value the POrder Id didn't show up in the debug output, but still getting the same error.
It seems that its not getting the oldvalues and returns a null, which is something strange. If you are not using a 'standard' datasource New/Old Values are not always available in the Row Updating event.
I am using a Grid View to display a dataset with no binding to an SQLdatasource.
There is a code snip posted on the net that is supposed to take care of that.
However, Command Arguments come from database to linkbutton. I've managed to get the row Index of the row that the user presses inside the Gridview with: Grid View Row row = (Grid View Row) ((Button)sender).
Andwhen one of these command buttons is cliked it must go to proper page.
