DropDownList control doesnt have CascadingDropDown properties

I'm attempting to follow the cascadingdropdown with database walk through. For some reason in the properties window of the dropdownlist control there isn't a CascadingDropDown property with plus sign all the properties needed to be set to get the example to work, (Category, ParentControID, PrompText, ServiceMethod, ServicePath.)

Does anyone know how to activate these property settings?

Hi,

did you add the CascadingDropDown extender before looking at the properties panel? At what point of the walkthrough are you experiencing this?

Thanks.

One of the first steps in the example is to add the three dropdownlists you'll need. This included in my case using the properties panel to rename each dropdownlist as I added them. Are you not supposed to view any properties of any control prior to adding the cascadingdropdown extender? If this is the case, shouldn't it be in the example?

Hi,

I have the same problem even worse!

When I try to add these property manually, I get an error"Attribute ParentControlID is not a valid attribute".

Thanks

Hi,

The design experience with the Toolkit has changed a fair amount since that walkthrough was written and we haven't had enough time to update it. The CascadingDropDown properties now appear in the Extenders section (it shows up between Data and Layout when sorting by Category) of the property grid. Expand that first and then you should be able to expand CascadingDropDown.

Thanks,
Ted
