Control.EnsureChildControls Method ()
Determines whether the server control contains child controls. If it does not, it creates child controls.
Assembly: System.Web (in System.Web.dll)
Themethod is typically used in composite controls, which are controls that use child controls for some or all their functionality. The method is called in order to make sure that child controls have been created and are ready to process input, to perform data binding, or to perform other tasks.
The GridView control is an example of a composite control. It creates child controls such as Table, TableRow, TableCell, Label, and TextBox controls, which are used to render the HTML table that the GridView generates.
In most cases, custom server control developers do not have to override this method. If you do override this method, use it in a way similar to the default behavior.
Legacy Code Example
This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
