Can I convert 'MsRichTextBoxXaml' to 'RadRichTextBox Xaml'?

[SPE]

Hi,

I have many string datas in RichTextBoxXaml format.

Like this,

<Section xml:space="preserve" HasTrailingParagraphBreakOnPaste="False" xmlns=" FontSize="12" FontFamily="Gulim" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left"><Run Foreground="#FFFF0000" Text="asdf" /></Paragraph><Paragraph FontSize="12" FontFamily="Gulim" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left"><Run Foreground="#FFFF0000" /></Paragraph><Paragraph FontSize="12" FontFamily="Gulim" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left"><Run Foreground="#FF000000" Text="qwer" />
</Paragraph></Section>



What I want to do is,

to convert this data into RadRichTextBox Xaml format.

Such as,

<t:RadDocument xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:t="clr-namespace:Telerik.Windows.Documents.Model;assembly=Telerik.Windows.Documents" version="1.1" DefaultPageLayoutSettings="816,1056" LayoutMode="Flow" PageViewMargin="10,10">    <t:Section>      <t:Paragraph>        <t:Span FontFamily="Verdana" FontSize="16" ForeColor="#FFFF0000" Text="asdfasdfwqtr..!!!!! dafsfd dafdsafsdfasdfasf" UnderlineColor="#FF000000" UnderlineDecoration="None" />      </t:Paragraph>    </t:Section>  </t:RadDocument>



I tried below code.

        private string ConvertMsXamlToTelerikXaml(string msXaml)
        {
            MsRichTextBoxXamlFormatProvider xamlProvider = new MsRichTextBoxXamlFormatProvider();
            var document = xamlProvider.Import(msXaml);
            RadRichTextBox richBox = new RadRichTextBox()
            {
                Document = document
            };

            XamlDataProvider provider = new XamlDataProvider();
            provider.RichTextBox = richBox;

            return provider.Xaml;
        }

But it always gives me a paragraph without any value.

- <t:RadDocument xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:t="clr-namespace:Telerik.Windows.Documents.Model;assembly=Telerik.Windows.Documents" version="1.1" DefaultPageLayoutSettings="816,1056" LayoutMode="Flow" PageViewMargin="10,10">

- <t:Section>

<t:Paragraph />

</t:Section>

</t:RadDocument>

How can I make telerik xaml successfully?

Thank you in advance.

Hi Sunmin,

The problem is that Section elements are not supported on import. As described in MSDN Sections are not part of the document model of RichTextBox.

If you modify your XAML to the following format:

<Paragraph FontSize="12" FontFamily="Gulim" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
    <Run Foreground="#FFFF0000" Text="asdf" />
</Paragraph>
<Paragraph FontSize="12" FontFamily="Gulim" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
    <Run Foreground="#FFFF0000" />
</Paragraph>
<Paragraph FontSize="12" FontFamily="Gulim" Foreground="#FF000000" FontWeight="Normal" FontStyle="Normal" FontStretch="Normal" TextAlignment="Left">
    <Run Foreground="#FF000000" Text="qwer" />
</Paragraph>

 it could be imported with MsXamlFormatProvider and exported with XamlFormatProvider in a way similar to the one in your snippet.

I hope this helps.

Hello,

Thank you for your help.

But what you recommended doesn't seem to work.



My snippet is below.

        public MainPage()
        {
            InitializeComponent();

            string textToConvert = @"<ParagraphFontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000""
FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left"">
    <RunForeground=""#FFFF0000"" Text=""asdf""/>
</Paragraph>
<ParagraphFontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal""
FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left"">
    <RunForeground=""#FFFF0000""/>
</Paragraph>
<ParagraphFontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal""
FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left"">
    <RunForeground=""#FF000000"" Text=""qwer""/>
</Paragraph>";

            string result = ConvertMsXamlToTelerikXaml(textToConvert);
        }

        private string ConvertMsXamlToTelerikXaml(string msXaml)
        {
            MsRichTextBoxXamlFormatProvider xamlProvider = new MsRichTextBoxXamlFormatProvider();
            var document = xamlProvider.Import(msXaml);
            RadRichTextBox richBox = new RadRichTextBox()
            {
                Document = document
            };
            XamlDataProvider provider = new XamlDataProvider();
            provider.RichTextBox = richBox;
            return provider.Xaml;
        }

In runtime, it throws an exception.


I really appreciate your help.

Thank you.

Hi Sunmin,

Actually I was mistaken in my previous reply.
The XAML serialization of the rich text boxes indeed looks like the snippets in your first post. The problem is that there is an interval just after the opening quotation mark in the declaration of xmlns. The whole string should look like this (after being escaped in VisualStudio):

string textToConvert = @"<Section xml:space=""preserve"" HasTrailingParagraphBreakOnPaste=""False"" xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"">
<Paragraph FontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left""><Run Foreground=""#FFFF0000"" Text=""asdf"" /></Paragraph><Paragraph FontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left""><Run Foreground=""#FFFF0000"" /></Paragraph><Paragraph FontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left""><Run Foreground=""#FF000000"" Text=""qwer"" />
</Paragraph></Section>";

On a side note, DataProviders have been implemented to help you bind the content of the document. If you just want to import and export the document, you should use XamlFormatProvider.
In a nutshell, the code that can be used to convert  the string above to our XAML format is:

            string textToConvert = @"<Section xml:space=""preserve"" HasTrailingParagraphBreakOnPaste=""False"" xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"">
<Paragraph FontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left""><Run Foreground=""#FFFF0000"" Text=""asdf"" /></Paragraph><Paragraph FontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left""><Run Foreground=""#FFFF0000"" /></Paragraph><Paragraph FontSize=""12"" FontFamily=""Gulim"" Foreground=""#FF000000"" FontWeight=""Normal"" FontStyle=""Normal"" FontStretch=""Normal"" TextAlignment=""Left""><Run Foreground=""#FF000000"" Text=""qwer"" />
</Paragraph></Section>";

            MsRichTextBoxXamlFormatProvider provider = new MsRichTextBoxXamlFormatProvider();
            RadDocument document = provider.Import(textToConvert);
            XamlFormatProvider telerikXamlFP = new XamlFormatProvider();
            string telerikXaml = telerikXamlFP.Export(document);

You can also find attached a demo illustrating the export and import. Kind regards,
