DataGridColumnCollection.RemoveAt Method
Assembly: System.Web (in system.web.dll)
public void RemoveAt ( int index )
public function RemoveAt ( index : int )
Parameters
- index
The index of the DataGridColumn-derived column in the DataGridColumnCollection to remove.
Use this method to remove a DataGridColumn-derived column object from a DataGridColumnCollection collection at the specified index.
The DataGrid control does not store the contents of its Columns collection in the view state. To add or remove a column dynamically, you must programmatically add or remove the column each time the page is refreshed. Provide a Page_Init function that adds or removes the column before the DataGrid control can reload its state and rebuild itself. Otherwise, the changes to the Columns collection are not reflected in the DataGrid control when it is displayed.

| Although you can programmatically add columns to or remove columns from the Columns collection of the DataGrid control, it is easier to list the columns statically and then use the Visible property to display or hide each column. |
