WebGrid - - HELP !!
posted

Hi everyone,

I have a WebGrid showing 3 records from Table#1 that is related to another Table#2 (using Primary and Foreign keys)

When I select any row and hit the [DELETE] key this is what happens :

1.  it goes ahead and deletes the selected row from the WebGrid. (now I have 2 rows)
2.  I catch the exception and show an error message (cuz it tried to delete a record related to Table#2)
3.  the page now shows the WebGrid with TWO records but WITHOUT the deleted row.


If I go and select any of the remaining 2 records this is what happens :

4.  it goes ahead and deletes the selected row from the WebGrid (now I have 1 row)
5.  I catch the exception and show an error message (cuz it tried to delete a record related to Table#2)
6.  the page now shows the WebGrid with TWO records AGAIN but WITHOUT the deleted row.
     It shows the record I deleted in Step 1 AND the record I haven’t deleted yet.


What I need is the complete set of 3 records back in the WebGrid AFTER catching the exception.

What can I do ?

Regards.

    without any code it is hard to know. But, you might want to look at just rebinding the data grid.

    There is a function  you can use.

    OnDeleteRow

    you can check for your record deletion code in this event then cancel if the delete is invalid.
