The Customization Form displays the headers of hidden rows. The form has two tabs: Rows and Categories. The Rows tab displays editor and multi-editor row headers. The Categories tab displays category row headers. The Categories page contains two buttons (New… and Delete) which allow category rows to be created and deleted directly in the Customization Form.
To hide a row, end-users should drag its header to the Customization Form. The Customization Form is a separate window which can be invoked by calling the VGridControlBase.ShowCustomization method.
