    In a std combo box with check boxes as you select a few items the text value appears in the combobox text area, until its full then is says n selected.

    I have a treeview in a combo box, with check boxes, how would I replicated this behaviour?

    Hi Andy,

    Our RadComboBox control does not offer the desired behavior out-of-the-box.

    However, you could review the checkbox functionality of our RadDropDownTree control and see if it fits your needs. You could customize the input field text by handling the OnClientEntryAdded event. You could calculate the length of the entries text and set it in the input field in the "n selected" format if it exceeds certain max length.

    If the RadDropDownTree control does not meet your requirements, please give us some more details on the desired implementation of the RadTreeView within a RadComboBox. Do you need the tree to be an ItemTemplate within the combo or something else?
