Thanks for the 2 suggestions, but I couldn't get either one to work for me.
What I was able to do was leverage the RadEditor which has a property simply called Text which does exactly what I want.
The label "lblBriefAnswer" is contained within an ItemTemplate of a GridTemplateColumn.
protected void lblBriefAnswer_PreRender(object sender, EventArgs e)
Label lblBriefAnswer = (Label)sender;
lblBriefAnswer.Text = HTML2PlainText(lblBriefAnswer.Text);
public static string HTML2PlainText(string htmlText)
RadEditor editor = new RadEditor();
editor.Content = htmlText;
String plainText = editor.Text;
