Examples

The following code example demonstrates how to override the RenderBeforeTag method. The code checks whether an a element is being rendered. If so, the overridden RenderBeforeTag method writes the opening tag of a small element. The sample for the RenderAfterTag performs the same check for the a element, and then writes the closing tag of the small element.

This code example is part of a larger example provided for the Html32TextWriter class.

// Override the RenderBeforeTag method to render the
// opening tag of a <small> element to modify the text size of 
// any <a> elements that this writer encounters.
protected override string RenderBeforeTag()
{
    // Check whether the element being rendered is an 
    // <a> element. If so, render the opening tag
    // of the <small> element; otherwise, call the base method.
    if (TagKey == HtmlTextWriterTag.A)
        return "<small>";
    return base.RenderBeforeTag();
}

' Override the RenderBeforeTag method to render the
' opening tag of a <small> element to modify the text size of 
' any <a> elements that this writer encounters.
Protected Overrides Function RenderBeforeTag() As String
    ' Check whether the element being rendered is an 
    ' <a> element. If so, render the opening tag
    ' of the <small> element; otherwise, call the base method.
    If TagKey = HtmlTextWriterTag.A Then
        Return "<small>"
    End If
    Return MyBase.RenderBeforeTag()
End Function
