protected:
 virtual System::Web::UI::HtmlTextWriterTag GetTagKey(System::String ^ tagName);

protected virtual System.Web.UI.HtmlTextWriterTag GetTagKey(string tagName);

abstract member GetTagKey : string -> System.Web.UI.HtmlTextWriterTag
override this.GetTagKey : string -> System.Web.UI.HtmlTextWriterTag

Protected Overridable Function GetTagKey (tagName As String) As HtmlTextWriterTag

Parameters

tagName: String

The markup element for which to obtain the HtmlTextWriterTag.

Returns

HtmlTextWriterTag

The HtmlTextWriterTag enumeration value; otherwise, if tagName is not associated with a specific HtmlTextWriterTag value, Unknown.

Examples

The following code example shows how to override the overload of the RenderBeginTag method that takes a string as its parameter. The string is passed to the GetTagKey method, which converts it to the corresponding HtmlTextWriterTag enumeration member, and then passes that to the RenderBeginTag overload that takes a HtmlTextWriterTag enumeration value as a parameter.

virtual void RenderBeginTag( String^ tagName ) override
{
   
   // Call the overloaded RenderBeginTag(HtmlTextWriterTag) method.
   RenderBeginTag( GetTagKey( tagName ) );
}

public override void RenderBeginTag(string tagName)
{
    // Call the overloaded RenderBeginTag(HtmlTextWriterTag)
    // method.
    RenderBeginTag(GetTagKey(tagName));
}

Public Overloads Overrides Sub RenderBeginTag(ByVal tagName As String)
    ' Call the overloaded RenderBeginTag(HtmlTextWriterTag) method.
    RenderBeginTag(GetTagKey(tagName))
End Sub

Remarks

If tagName is null, an empty string (""), or cannot be found in the table of markup tag names, the GetTagKey method returns the Unknown field.
