RadHtmlPlaceholder Events

One of the important custom events that RadHtmlPlaceholder exposes is the UrlLoaded event. This event occurs as soon as the external url that is set as a source is loaded.

<UserControl x:Class="RadHtmlPlaceholderDemo.Page"  
             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="700" 
             Height="400"> 
    <Grid x:Name="LayoutRoot"  
          Margin="10" 
          Background="White"> 
        <Border BorderBrush="Black" BorderThickness="1"> 
            <telerik:RadHtmlPlaceholder x:Name="RadHtmlPlaceholder1"  
                                        SourceUrl="http://www.bing.com" 
                                        UrlLoaded="RadHtmlPlaceholder_UrlLoaded" /> 
        </Border> 
    </Grid> 
</UserControl>
