HtmlInputRadioButton.RenderAttributes Method

Renders the HtmlInputRadioButton control attributes to the specified HtmlTextWriter object.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

protected:
virtual void RenderAttributes (
	HtmlTextWriter^ writer
) override
protected void RenderAttributes (
	HtmlTextWriter writer
)
protected override function RenderAttributes (
	writer : HtmlTextWriter
)

Parameters

writer

An HtmlTextWriter that receives the rendered output.

The RenderAttributes method writes the Value property as an attribute of the HtmlInputRadioButton control and then calls the base class's RenderAttributes method

The RenderAttributes method is used primarily by control developers extending the functionality of the HtmlInputRadioButton control.

The following code example demonstrates how to override the RenderAttributes method in a custom server control so that specific title text is always displayed for the HtmlInputRadioButton.
