[Solved] Problem with Richtextbox inside childwindow

[aubrey]

Good day Telerik Team,

I am currently using your new "RadControls for Silverlight Q2 2011 Demos", and it works fine.

When i tried to put radrichtextbox inside a new ChildWindow and I set the "IsReadOnly" property to true:

<telerik:RadRichTextBox Grid.RowSpan="2" HorizontalAlignment="Stretch" IsContextMenuEnabled="False" IsReadOnly="True" IsSelectionEnabled="False" IsSelectionMiniToolBarEnabled="False" IsSpellCheckingEnabled="False" LayoutMode="Paged" Margin="0,0,13,29" x:Name="rtbPrev" VerticalAlignment="Stretch" AllowScaling="True" Style="{StaticResource RadRichTextBoxStyle1}" IsImageMiniToolBarEnabled="False" IsInHeaderFooterEditMode="False" IsFocusable="False"/>

and I create an instance of this childwindow:

private void Doc_Preview(object sender, System.Windows.RoutedEventArgs e)
{
            Preview prev = new Preview();


            RadDocument doc = new RadDocument();


            this.radRichTextBox1.Document.Selection.SelectAll();


            doc = this.radRichTextBox1.Document.Selection.CreateDocumentFromSelection();
            radRichTextBox1.Document.Selection.Clear();
            doc.CaretPosition.MoveToFirstPositionInDocument();

            prev.rtbPrev.Document = doc;
            prev.rtbPrev.Document.Sections.First.Headers = radRichTextBox1.Document.Sections.First.Headers;
            prev.rtbPrev.Document.Sections.First.Footers = radRichTextBox1.Document.Sections.First.Footers;
            prev.rtbPrev.Document.SectionDefaultPageOrientation = radRichTextBox1.Document.Sections.First.PageOrientation;
            prev.rtbPrev.Document.SectionDefaultPageMargin = radRichTextBox1.Document.Sections.First.ActualPageMargin;
            prev.rtbPrev.LayoutMode = radRichTextBox1.Document.LayoutMode;
            prev.rtbPrev.Document.CopyPropertiesFrom(radRichTextBox1.Document);

            prev.rtbPrev.ScaleFactor = new Size(0.55, 0.55);
            prev.Show();
}

And when I call Doc_Preview() the main screen turns to white, and i lose my control on it.

But when I turn "IsReadOnly" to false the child window will appear and my main page/screen does not freak out.

I also tried this one using your "RadControls for Silverlight Q1", and it works fine even if i turn  radrichtextboxs "IsReadOnly" to true. 

Is there a way that I can set the property of a radrichtextboxs "IsReadOnly" to true inside a childwindow and I will not lose control of my main screen (using your "RadControls for Silverlight Q2 2011 Demos")?   

hoping for your reply,
Aubrey :')

Good day telerik,

Is this problem possible to be resolve? or is it a bug when a radrichtextbox is put into a childow and setting the "IsReadOnly" property to true(which causes the main page to turn to white)? :(

Hoping for your reply,
Aubrey :(

Hi Aubrey,

Thank you for reporting this issue. I have tested this scenario with the development version and everything worked OK. Once the Q2 is out (in less than a week), the issue should be resolved.
As a workaround with the Q2 Beta version of the controls (2011.2 623), you can set the IsReadOnly to True when the RichTextBox is loaded, e.g.:

private void rtbPrev_Loaded(object sender, RoutedEventArgs e)
{
    ((RadRichTextBox)sender).IsReadOnly = true;
}

The Telerik points in your account have been updated in appreciation of your involvement. Greetings,

Hi Iva,

thank your for the reply, and thank you for the points, :)

I've loaded the richtexbox and set IsReadOnly to True, but theres an exception thrown:
"Unable to cast object of type 'ReportsUI.Preview' to type 'System.Windows.Controls.RichTextBox'."

heres the code:

private void RtbLoad(object sender, RoutedEventArgs e)
{
    ((RichTextBox)sender).IsReadOnly = true;
}

is there a way i can fix this?

thanks, 
Aubrey :)

Hi Iva,

i already know my mistake. i got it now. since i am using RadRichTextbox  i cant cast it richtextbox. heres my code:

private void RtbLoad(object sender, RoutedEventArgs e)
{
    ((RadRichTextBox)sender).IsReadOnly = true;
}

thanks for the thought Iva, :)

regards,
Aubrey :)
