Hello,
I am using the ComboBox from the Ajax Toolkit 15.1 in VS2013. However I get the following error:
__ComboBox - ComboBox1
There was an error rendering the control.
Value cannot be null. Parameter name: Stream
__
The comboBox does not render in design mode and when I try running it the dropdown appears outside of the textbox. Can anyone tell me what the problem is. Trioed changing the Render mode to Block , but this does not resolve the issue. Call ComboBox definition below. Appreciate if some could help with this error.
regards
Pat
