HtmlInputImage::RenderAttributes Method

Renders the HtmlInputImage control's 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

Parameters

writer
Type: System.Web.UI::HtmlTextWriter
The HtmlTextWriter that contains the output stream to render on the client.

ExceptionCondition
HttpException

The Src property contains a malformed URL.

The RenderAttributes method resolves the URL set in the Src property, writes the onclick attribute of the rendered HtmlInputImage control if the CausesValidation property is true, and finally calls the base RenderAttributes method. If the value of the Src property is a malformed URL, an HttpException exception is thrown.

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

The following code example demonstrates how to override the RenderAttributes method in a custom server control so that specific alternate text, accessible as a ToolTip, is always displayed with the HtmlInputImage.
