DeleteT_ and ValidationException

Question

User1414551024 posted

When ValidationException is thrown in InsertT_ partial method it's nicely handled and displayed as user-friendly red error message. That's nice.

I tried to throw same exception in DeleteT_ (to handle DELETE failed because of FOREIGN KEY constraint) hoping to have it also nicely displayed on screen but it shows as unhandled javascript exception. Is there a trick I can use to have it also handled similarly?

Hmmm, not sure why that wouldn't work.  Is this with Linq To Sql or Entity Framework?  I assume you're using the final 3.5 SP1 bits?

We're using linq to sql, final 3.5SP1. Before that we used SP1 beta (If I remember correctly when installing final sp1, we didn't do uninstall of the beta).

I also noticed someone else reported exact same issue some time ago, without resolution on the forum.

This reproduced for me with Linq2Sql and we will look into it and see if we can come up with a workaround for you.

I think I understand the cause: the Delete link has CausesValidation="false".  If you set that to true instead, it should work.  Could you please give it a try and let use know?

thanks,

 Works a charm, of course. When you see the solution it becomes obvious, but prior to that .... ;)
