HtmlContainerControl Class

Serves as the abstract base class for HTML server controls that map to HTML elements that are required to have an opening and a closing tag.

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

[AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)]
public ref class HtmlContainerControl abstract : public HtmlControl
<asp:HtmlContainerControl />

The most common controls with a closing tag are the <form>, <table>, <tr>, <td>, <a>, and <span> elements.

The InnerText and InnerHtml properties allow you to manipulate the content between the opening and closing tags of HtmlContainerControl-derived controls.

For a list of initial property values for an instance of HtmlContainerControl, see the HtmlContainerControl constructor.

A new instance of this class is not created directly.

Caution noteCaution:

If you use the InnerHtml property to specify the text between the opening and closing tags of an HTML server control, the text is not HTML encoded. This makes it possible to embed script within HTML tags in the text. When using the InnerHtml property, be sure to validate the value to reduce security vulnerabilities. Otherwise, consider using the InnerText property instead.

The following code example demonstrates how to use the InnerHtml property of this class to dynamically generate a message on a Web page.

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