RadRichText LightSwitch Data-binding

[Brian]

You guys did a tutorial on the RadRichText custom control for Lightswitch http://www.telerik.com/products/lightswitch-support.aspx
, I was wondering if you could expand on it and show us how to Data-bind a RadRichTextBox with a Xaml Data Provider and use in a LightSwitch app and bind it to a table built in Lightswitch. I have been working on this for many hours and no luck. Thanks for your help...Brian

Hi Brian,

In order to get the data binding working in LightSwitch, you have to follow these steps:

1. Create the appropriate fields and queries in your LightSwitch project, just as you would if you weren't using a custom control.
2. Open RichTextControl.xaml as in the demo and add this right above the RadRichTextBox instance:

3. <telerikXaml:XamlDataProvider RichTextBox="{Binding ElementName=radRichTextBox1}" Xaml="{Binding Screen.MyXamlProperty}" />

   You have to change the Xaml binding to be bound to whatever you want to view in your RichTextControl.

We've tried this approach with a string property and it worked perfectly. You should be able to use it with a database query without a problem.

Ivailo, I tried to enter the code you suggested:

<telerikXaml:XamlDataProviderRichTextBox="{Binding ElementName=radRichTextBox1}"
			Xaml="{Binding Screen.MyXamlProperty}" />

I get an error:
Error	5 The type 'telerikXaml:XamlDataProviderRichTextBox' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

I tried entering a RadRichTextBox with the Wizard and selected Text Box or Rich Text Box option
on the first screen and this is the code it came up with:

			<telerik:RadRichTextBox.Resources>
				<my:XamlDataProvider
					x:Key="provider"
					RichTextBox="{Binding ElementName=radRichTextBox1}" />
			</telerik:RadRichTextBox.Resources>




Any suggestions on how to get you code working in the example you guys created...Thanks

Hi Brian,

There is a small mistake in your XAML code. Actually, there is a space between XamlDataProvider and RichTextBox, as I have posted the code and if you change that, it should compile OK.
