Hi there,
I am using Q3, asp.net 2.0 and I have run into this error: Exception has been thrown by the target of an invocation.
I do know what causes it, but I cannot find out how to solve.
I wrap a detailsview into the RadAjaxPanel and everything works fine. The problem is that I have some textboxes which do not allow the value null. Everything is fine if I type some values in these textboxes, but it throws this error if this textboxes are left null.
I have set the RequiredFieldValidator for these textboxes, hoping it to show some alert messages to users to type in these boxes but they do not work with RadAjaxPanel. Perhaps I miss something with using validation with RadAjaxPanel?
Please advice.
Thanks.
