HtmlSelect::RenderChildren Method
Renders the HtmlSelect control's child controls to the specified HtmlTextWriter object.
Assembly: System.Web (in System.Web.dll)
Parameters
- writer
- Type: System.Web.UI::HtmlTextWriter
The HtmlTextWriter that receives the rendered content.
| Exception | Condition |
|---|---|
| HttpException | Multiple items were selected but the Multiple property is set to false. |
The RenderChildren method overrides the base class's RenderChildren method without calling the base method. Each of the <option> elements between the opening and closing <select> tags is rendered with a value attribute, a selected attribute if the item is selected, and its associated text.
If multiple items were selected but the Multiple property is set to false, then an HttpException exception is thrown.
The following code example demonstrates how to override the RenderChildren method so that it always displays default option text in a custom HtmlSelect server control.
