Hi,

I have a drop down list (with Autopostback="true", and having few other text fields) inside a Web Dialog Window. Depending on the value selected from this list, another control needs to be shown.

It doesn't seem to work when I change the select value. I have a Submit button for this dialog window (simply closes the window for now), which when clicked makes the postback and update the 2nd control according to the drop down list value selected.

With firebug, there seems to be a post for the form but with a "500 Internal Server Error" and a response of "Exception Details: System.IndexOutOfRangeException: Index was outside the bounds of the array."

And here is the stack trace:

Any help is appreciated.
