How can I perform text formatting with a ReadOnly document?

Hi Craig,

I would think that formatting should work as long as your formatting code's text change isn't doing a read-only check.

If you think there is a problem, please e-mail us a new simple sample project that shows the issue so we can debug. Thanks!

You can repro this using the HTML Editor (Web Lang Add-On) sample in the Actipro Sample Browser. In the sample's MainControl.xaml file, set the SyntaxEditor's EditorDocument's IsReadOnly property to true:


<docking:Workspace>
    <editor:SyntaxEditor 
            x:Name="syntaxEditor" 
            DocumentParseDataChanged="OnSyntaxEditorDocumentParseDataChanged" 
            UserInterfaceUpdate="OnSyntaxEditorUserInterfaceUpdate"
            ViewSearch="OnEditorViewSearch"
            ViewSelectionChanged="OnSyntaxEditorViewSelectionChanged"
            >
            <editor:EditorDocument xml:space="preserve" IsReadOnly="true">

When you run the sample and press the Format Document button, you'll see that the text isn't formatted.

Hi Craig,

Thanks for the repro steps. It happens there because our XmlTextFormatter does have the read-only check in its options:

var options = new TextChangeOptions() {
    RetainSelection = true,
    CheckReadOnly = true,
    OffsetDelta = TextChangeOffsetDelta.SequentialOnly
};

For the next version, we're going to disable the format commands when they will perform on a read-only document (for toolbar buttons). With that update and with the current code, if you are using our XML formatter, you'd probably have to set the document read-only state to false, then call the format programmatically and directly via the service, and set read-only back to true.
