First of all, I would like to ask you to elaborate on the implementation of the RadComboBox. The RadComboBox has its own build-in feature for CheckBoxes
, by simply enabling its CheckBoxes
property. Did you purposely implemented the approach using a CheckBoxList in its ItemTemplate? However, if the CheckBoxes feature of the RadComboBox is enabled, you could easily achieve the desired functionality, by handling the OnTextChanged
event of the control. The event would be fired, once the client selects the desired checkboxes from the RadComboBox and the control is blurred. At the OnTextChanged
event handler, you could access the checked items and populate the other control. I am sending you a sample page, demonstrating the implementation of the above suggestion.
