Telerik,

I've got a regex control attached to a text box validating a list of email addresses. When the set of email addresses is invalid a water mark appears in the textbox with a message 'Invalid email' displaying in black font. It should be red font, but it looks like the radInput_error_default event is not being triggered and associated with the css that displays red font. The css that is being used is the '.RadInputMgr_Default' with a color = black. Below is the code for a sample application that does work. Note the ajax toolkit script manager is being used.

Can you shed any insight into this problem?

Peter

Hello Peter,

I tested the first code snippet that you wrote and the styles are applying right here. I just removed the
RadInputManager1's OnValidating and ScriptManager's OnAsyncPostBackError events since you didn't post their code. Please check their code for some modifying of the styles or eventual errors. I also see that you don't use OnValidating in the working version of the code, I don't see other significant differences, so this could really be the issue.

Kind regards,
Vasil
