DataGridColumnCollection.Add Method
Assembly: System.Web (in system.web.dll)
public void Add ( DataGridColumn column )
public function Add ( column : DataGridColumn )
Not applicable.
Parameters
- column
The DataGridColumn-derived column object to append to the DataGridColumnCollection.
Use this method to add a DataGridColumn-derived column object to the end of a DataGridColumnCollection collection.
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. |
