#Remarks
This event is triggered when the GridViewDataColumn.DataItemTemplate is null (Nothing in VB) and the column does not display “*******“ (see ProtectedContentText). To specify a custom ITemplate, handle this event, pass the custom ITemplate object to the handler’s CreateCustomItemTemplateEventArgs.Template parameter and set the Handled parameter to true. If you set Handled to true and do not initialize Template, the default column behavior will be used (the Object.ToString values will be displayed).
