RadHtmlPlaceholder SourceUri

[Edward]

I am using a Url to initially set a Telerik RadHtmlPlaceholder control.  I then perform some stuff which will return a new Uri which I will want to display on the same Telerik RadHtmlPlaceholder control.   The new Url is not displayed.  I am binding the SourceUri to just a typical CLR property. 

 

 

 

 

<telerik:RadHtmlPlaceholder x:Name="_htmlReport" SourceUrl="{Binding Path=SourceUri, Mode=TwoWay}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Visible" />

 

 

 

 

 

 

 

 

public Uri _sourceUri = new Uri("http://www.google.com/");

 

 

 

public Uri SourceUri {

 

 

 

get {

 

 

 

return _sourceUri;

 

}

 

 

set {

 

_sourceUri =

 

value;

 

}

 

 

 Should I elevate this to a DependencyProperty?  Seems as if it would work if the initial Url is displayed but why not the updated Url?

Hello Edward,

You don't have to use a DependencyProperty. However, for a change notification to occur in a binding between a bound client and a data source, your bound type should either:

• Implement the INotifyPropertyChanged interface (preferred)

or

• Provide a change event for each property of the bound type.

I prepared a sample project illustrating the first approach. Please give it a try and let me know if it works for you or if you need more info.
