Question

when I tried to update my gridview which is connected using <asp:LinqDataSource> and Enabling update and delete in this data Source I got an exception told me that :

javaScript runtime error:
Sys.WebForms.PageRequestManagerServerErrorException: Could not find a
row that matches the given keys in the original values stored in
ViewState. Ensure that the ‘keys’ dictionary contains unique key
values that correspond to a row returned from the previous Select
operation.

How Can I solve this exception ?

Answer 1

You should add DataKeyNames="ID" in Gridview properties ID is the key column of the database table .
