Grid View for ASP.NET WebForms - How to conditionally make cell editors read-only

Implementation Details

This example demonstrates how to set a grid cell editor's ReadOnly property based on the grid's state. The example application allows you to edit a field value in a new row, but the editor becomes read-only when you try to edit an existing row.

The ReadOnly property is set in the ASPxGridView.CellEditorInitialize event handler based on the value of the IsNewRowEditing property.

protected void gridView_CellEditorInitialize(object sender, ASPxGridViewEditorEventArgs e) {
	ASPxGridView grid = sender as ASPxGridView;
	if (e.Column.FieldName == "CategoryID")
		e.Editor.ReadOnly = !grid.IsNewRowEditing;
}
