HtmlTextArea::OnPreRender Method
Raises the PreRender event.
Assembly: System.Web (in System.Web.dll)
The OnPreRender method notifies the HtmlTextArea control to perform any necessary steps prior to saving the view state and rendering content.
The OnPreRender method is used primarily by control developers extending the functionality of the HtmlTextArea control.
Notes to Inheritors:When overriding the OnPreRender method in a derived class, be sure to call the base class's OnPreRender method so that the HtmlTextArea control is properly registered with the page.
The following code example demonstrates how to override the OnPreRender method to always display 5 rows and 75 columns in a custom HtmlTextArea server control.
