When using a CascadingDropDown, it always clears the Items of the target dropdown, even if the CCD is disabled.
If the CCD is disabled, it shouldn't touch the target control at all. In read only scenarios we sometimes disable ajax to get certain behaviors and this interferes.
I think this can be fixed simply by wrapping the body of CascadingDropDown_ClientStateValuesLoaded inside an if(Enabled) block.
Comments: This ticket was filed for a pre-15.1 version of AJAX Control Toolkit. If this is still an issue in v15.1 or later, please create a new inquiry.
