OnClientDropDownClosed and EnableCheckAllItemsCheckBox Properties

[Greg]

I am using multiple RadComboBoxes to cascade selectable values. I am using the OnClientDropDownClosed client-side event to  fire the server-side ItemsRequested event to populate the next combobox in my sequence. Data for each combobox loads properly, but if I set the EnableCheckAllItemsCheckBox property to true, when I select the next combobox and before the ItemsRequested server-side event fires, I receive the following error:

"Microsoft JScript runtime error: 'this.get_checkAllCheckBoxDivElement().0.offsetHeight' is null or not an object"

Does anyone have any ideas how I can make all of these parts work together?

Thanks for any help.....

Hi Greg,

I am afraid that simultaneous usage of Load On Demand and Checkboxes features is not supported.
