I cannot seem to figure out how to do a Selection Alignment in the new RichTextBox, I have an idea that I need to convert the selection into the Paragraph type which supports alignment, but cannot seem to figure this out. None of the Silverlight examples have this, but I'
m sure it is possible.
I have this code, that does not work - as I think I need the selection to be a Paragraph as it always returns and Exception "Value does not fall within the expected range".
Editor.Selection.SetPropertyValue(Paragraph.TextAlignmentProperty, TextAlignment.Left)
I make sure I check for a Valid Selection first, code like the following works for "Bold":
If Editor.Selection.Text.Length > 0 Then ' Text Selected
If TypeOf Editor.Selection.GetPropertyValue(Run.FontWeightProperty) Is FontWeight _
AndAlso DirectCast(Editor.Selection.GetPropertyValue(Run.FontWeightProperty), FontWeight) = FontWeights.Normal Then
Editor.Selection.SetPropertyValue(Run.FontWeightProperty, FontWeights.Bold)
Else
Editor.Selection.SetPropertyValue(Run.FontWeightProperty, FontWeights.Normal)
End If
End If
Editor.Focus()
Example in XAML:
<Paragraph TextAlignment="Right">Example</Paragraph>
The above works in the contents of a RichTextBox however I need to do this programatically based on a selection - like in WordPad.
