show the RadRichTextBox selections' states problem

[Chen]

Hello.

 Somewhile it shows the FontSize ,FontFamily and HorizontalAlignment only. And Somewhile it shows nothing. I want to show more, such as FontWight , UnderLine state and so on.

And when I don't select text, and I set the FontSize, FontFamily,  FontWight, UnderLine and so on, they won't change the default text style. And the UnderLine attribute is readonly. How can I set it?

Thanks.
Chen

Hi Chen,

We are introducing default font properties in the next official release, Q3 2010, which is due in mid-November. As of now, you can change them as described in this forum post, which you might have already seen.
The Underline property is ReadOnly, as there are various line types you can choose to underline something. You should use the UnderlineDecoration property in your case. All in one, this is how you set the FontWeight and the UnderlineDecoration:

span.FontWeight = FontWeights.Bold;
span.UnderlineDecoration = UnderlineTypes.Line;


As for the selection event, there is a SelectedLayoutBoxChanged event, which RadRichTextBox exposes. Have you tried using that? You might also want to check out RadRichTextBoxRibbonUI if you still haven't.

Kind regards,

Hello Iva,

Sorry for my unclear description. And thank you for your detail  answer.

Exactly, I just want to show the detail message of  text selected in the RibbinBar.  

    xmlns:telerikRibbonBar="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.RibbonBar"
    <telerikRibbonBar:RadRibbonTab x:Name="ribbonBar" Grid.ColumnSpan="2">
            <telerikRibbonBar:RadRibbonGroup>
                        .......................

The Demo http://demos.telerik.com/silverlight/beta/#RichTextBox/MSWord doesn't have this problem. When I select some text, the RibbinBar will change at the same time.
Is it the problem of  version?

Thanks.

Hi Chen,

Do you mean that when you select some bold text, for example, the Bold button in the RibbonBar does not appear pressed?
You can see the code used in the demo by pressing the "View Code" button in the upper right corner. It uses RadRichTextBoxRibbonUI instead of RadRibbonBar, which extends its functionality. You can also recreate the whole RibbonUI by just adding RadRichTExtBoxRibbonUI to the page from the toolbox, or later from the context menu of the designer:

Try it out and let us know if your problem persists.
