HtmlGenericControl.TagName Property

Gets or sets the tag name of an element that contains a runat= "server" attribute.

[Visual Basic]
Public Shadows Property TagName As String
[C#]
public new string TagName {get; set;}
[C++]
public: __property String* get_TagName();
public: __property void set_TagName(String*);
[JScript]
public hide function get TagName() : String;
public function set TagName(String);

Property Value

The tag name of an element.

Remarks

Use this property to programmatically determine the element name of the HTML server control. For example, the TagName property for a server-side <span id="MySpan" runat= "server"/> element contains the value "span".

Example

[Visual Basic, C#, JScript] The following example demonstrates how to use the TagName property to programmatically change a tag name from "Body" to "Font" and back.
