TextBox.AddAttributesToRender Method

This method supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Adds HTML attributes and styles that need to be rendered to the specified HtmlTextWriter instance.

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

protected override void AddAttributesToRender (
	HtmlTextWriter writer
)
protected void AddAttributesToRender (
	HtmlTextWriter writer
)
protected override function AddAttributesToRender (
	writer : HtmlTextWriter
)

Parameters

writer

An HtmlTextWriter that represents the output stream to render HTML content on the client.

This method is used primarily by control developers to insert the additional attributes and styles to the HtmlTextWriter output stream for a TextBox control. This method overrides WebControl.AddAttributesToRender.

The following code example demonstrates how to override the AddAttributesToRender method in a custom server control, so that the TextBox control text always appears bold.
