Examples
The following code example shows how you can set bold formatting for the selected text.
'Set Bold formatting to selected content
Private Sub BtnBold_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
If MyRTB IsNot Nothing Then
If TypeOf MyRTB.Selection.GetPropertyValue(Run.FontWeightProperty) Is FontWeight _
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
End If
End Sub
//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);
else
MyRTB.Selection.ApplyPropertyValue(Run.FontWeightProperty, FontWeights.Normal);
}
