Hello Paul,

Have you tried WebGrid's sample on IntegrationwithWebCombo.NET.aspx? This sample inherits from a master page as well that might be the same as your scenario.

Do you have any simple working sample that I can try from my end?

Thank you.

Hi Martin,

I've included a sample of what I can't get working.

Thanks for your time

Paul

Hello,

I've successfully replicated your issue on my end.

The error occurs because you set ClientIDMode to Static. When you use Master Page, the combo id will get changed and you could not use static id because it will detect as an incorrect id.

Try to set the ClientIDMode to AutoID and your project will work without any error.

Hope this helps.

Thank you.

Hi Martin,

Yup I've got it solved now.  I didn't actually mean to have ClientIDMode="static" in the version I sent to you; I tried that to solve my issue.  To actually fix the problem I had to specifically set ClientIDMode="AutoID".  I thought this was the default since I haven't specifically set the ClientIDMode anywhere within my control hierarchy.  Which is the reason I didn't try it.

Thanks for your help on this issue, I've got another one now though which I'll post in another topic 

Paul
