Crash when using PageLayoutSettings

[Iwhp]

The following code crashes:

Error message:

When using code like this, it works:

            RadDocument document = new RadDocument();
            document.LayoutMode = DocumentLayoutMode.Paged;
            document.DefaultPageLayoutSettings.Width = 400;
            document.DefaultPageLayoutSettings.Height = 400;
            RadRichTextBox1.Document = document;

Any ideas?
Thankx, Harry

Hello Harry Pfleger,

The problem is most probably related to an issue of Silverlight with loading object properties that are of type float. In this case PageLayoutSetting.With and Height properties are float because of specifics of RadDocument measurement system. This is why we created a special type converter for the PageLayoutSettings class, which allows Height/Width properties to be specified as strings:

DefaultPageLayoutSettings="440,440"

I hope this helps.

Hi Mike

thankx for the reply.
I changed my code to

<telerik:RadDocument x:Name="RadDocument1"
                                     LayoutMode="Paged"
                                     DefaultPageLayoutSettings="400,400">

and it did NOT work. Is this how it should be and work?

Cheers Harry
