I have a radgrid with one column called ApplicationName. When I click the "Add New Record" button to add a new record and fill out the textbox, I want to check the textbox to make sure there is not a duplicate ApplicationName in the database. How do I access the textbox to perform validation on it and what event do I place the code inside. I thought it would be the ItemCommand evnet but it seems to happen after the insert is completed.
Do you have an example? I looked at the examples on the website and could not find something to use.

Firstly, you should turn of AllowAutomaticUpdates/AllowAutomaticInserts, if you have it enabled, since you can't perform the check using that feature. Next you should handle the InsertCommand/UpdateCommand of the grid to perform you duplicate check. If it fails stop the update from happening
I hope that helps.

Cori, you are not helping :o(
Read Richards post. He needs to know exactly how to validate the field (so do I).
And your advise is like: Yeah, you can do it.
Thanks for nothing.

I hate to interfere in such discussions but hey, you are behaving strange. Cori is obviously trying to help and I suppose he is not obliged to do so. Not to say that this thread is 4 months old. In my opinion you shoot yourself in the foot with such answers.
Don't get me wrong, this is just my 2c.
Here is something you could start with:

Diego,
You just did wat Cori supposed to: YOU ACTUALLY HELPED WITH YOUR POST!
As I understand you should post in here in case you have a question or you have an answer to somebody's question.
Nobody needs to be cheered up with something like 'Yeah, you can do it! Keep looking.'
You can think that I'm strange but that's what I think. This is not a social network but developer's one.
Thank you for your help!
