Hi,
I'm working on a Silverlight program, which is used to display the preview of an email. Once user entered the email and clicked preview button, that message will display as a html content in preview window, which has created using a telerik RadPlaceHolder. But when click the the button it gives the following error. Can someone help me to sort out this issue. Kindly note that I'm silverlight beginner.
The invocation of the constructor on type 'Telerik.Windows.Controls.RadHtmlPlaceholder' that matches the specified binding constraints threw an exception. [Line: 9 Position: 77]
This is my code
<telerik:RadWindow x:Class="Mcs.Crm.ReportBursting.Controls.PrintPreview"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
Width="400"
Height="300" HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid x:Name="LayoutRoot" Background="White">
<Border BorderBrush="Black" BorderThickness="1">
<telerik:RadHtmlPlaceholder x:Name="RadHtmlPlaceholder1" Margin="10"/>
</Border>
</Grid>
</telerik:RadWindow >
public partial class PrintPreview : RadWindow
{
string mHtml;
public PrintPreview()
{
InitializeComponent();
}
public PrintPreview(string html)
{
try
{
InitializeComponent();
}
catch (Exception)
{
throw;
}
mHtml = html;
Loaded += new RoutedEventHandler(Page_Loaded);
}
private void Page_Loaded(object sender, RoutedEventArgs e)
{
RadHtmlPlaceholder1.HtmlSource = mHtml;
}

This error usually appears if there is a missing Telerik dll or the referenced Telerik dlls are of different versions. Can you double check this? And after this Clean/Rebuild the project.
Also, you can find additional information about the error by clicking the View Details link in the exception tooltip that is shown on the line of the error.
I hope that helps.

I noticed that you already opened a support ticket with the same question and the issue seems to be resolve by enabling the Windowless mode of the Silverlight application. Can you confirm this?
