Toggle Grid columns/headers based on ComboBox CheckBox Items

[Bobby]

I have a WPF Grid, a Combo Box and check box fields as items of the combo box. Combobox items are the grid headers/columns. Currently, the ComboBox is binded to the columns of the Grid and Grid header is toggeled based on the toggling of the checkbox items of Combobox.Now, I have to change this behaviour so that only some fileds are visible on the grid and those which are not visible are availabe in the Combobox as non-selected items with the fields that are visible on the grid as selected items. Toggling the checkbox items in the combobox would toggle the grid header/column visibility. Please suggest.

Hi Bobby,

I would suggest that you check the following help topic:
http://www.telerik.com/help/wpf/radcombobox-howto-enable-disable-radcombobox-items.html -
it explains how you could enable/disable the items of RadComboBox.

Hope this will help.
