Question

I’m using a gridview and a SqlDataSource.

In the database, I’ve set a unique constraint on one of the columns.

When I’m changing the value of a cell from a row in the gridview with a new value but the value already exists in other row in the same column it gives me the error :

Cannot insert duplicate key row in object ‘dbo.tb1’ with unique index ‘IX_tb1’.
The statement has been terminated.

I need to show a friendly message to the user for example in a label

Error: value already exists

Is there any way of doing this? Because I’m not using any sql command to catch something.

Thanks

Take a look at this answer. You need to use an event of the sqldatasource in order to handle the exception to show something friendly to the user.
