Control::RenderChildren Method

Outputs the content of a server control's children to a provided HtmlTextWriter object, which writes the content to be rendered on the client.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)
protected public:
virtual void RenderChildren(
	HtmlTextWriter^ writer
)

Parameters

writer
Type: System.Web.UI::HtmlTextWriter

The HtmlTextWriter object that receives the rendered content.

This method notifies ASP.NET to render any Active Server Pages (ASP) code on the page. If no ASP code exists on the page, this method renders any child controls for the server control. This method is called by the Render method.

The following example overrides the RenderChildren method in a custom server control. It determines whether the current control has any child controls in its ControlCollection object. If it does, it uses the Count property to iterate through the collection. As it encounters each child control, it uses the RenderControl method to render the parent control, and all of its child controls, to the containing page.

The overridden Render method then calls the overridden RenderChildren method.
