                AndAlso (CType(MyRTB.Selection.GetPropertyValue(Run.FontWeightProperty), FontWeight) = FontWeights.Normal) Then
                MyRTB.Selection.ApplyPropertyValue(Run.FontWeightProperty, FontWeights.Bold)
            Else
                MyRTB.Selection.ApplyPropertyValue(Run.FontWeightProperty, FontWeights.Normal)
            End If

//Set Bold formatting to selected content
private void BtnBold_Click(object sender, RoutedEventArgs e)

    if (MyRTB != null)
    {
        if (MyRTB.Selection.GetPropertyValue(Run.FontWeightProperty) is FontWeight && ((FontWeight)MyRTB.Selection.GetPropertyValue(Run.FontWeightProperty)) == FontWeights.Normal)
            MyRTB.Selection.ApplyPropertyValue(Run.FontWeightProperty, FontWeights.Bold);
