LinkButton.AddParsedSubObject Method

Notifies the control that an element, either XML or HTML, was parsed, and adds the element to the control's ControlCollection object.

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

protected:
virtual void AddParsedSubObject (
	Object^ obj
) override
protected void AddParsedSubObject (
	Object obj
)
protected override function AddParsedSubObject (
	obj : Object
)

Parameters

obj

An Object that represents the parsed element.

The following code example demonstrates how to override the AddParsedSubObject method in a custom LinkButton server control so that it either sets the text property to the parsed object's text property, if the parsed object is a Literal object, or to an empty string otherwise.

No code example is currently available or this language may not be supported.
