    I get a weird binding error if I use the namespace:








    This error does not occur if I use the namespace:









    The binding error is as follows:

    System.Windows.Data Error: Failed to connect to index '0' in object 'System.Collections.ObjectModel.ReadOnlyObservableCollection`1[System.Windows.Controls.ValidationError]' (type 'System.Collections.ObjectModel.ReadOnlyObservableCollection`1[System.Windows.Controls.ValidationError]'). BindingExpression: Path='(Validation.Errors)[0].ErrorContent' DataItem='Telerik.Windows.Controls.RadComboBox' (HashCode=6993202); target element is 'Telerik.Windows.Controls.Chromes.ValidationTooltip' (Name='ValidationTooltip'); target property is 'TooltipContent' (type 'System.Object').

    This is just with using the default XAML of <telerik:RadComboBox />

    I'd prefer to use the XAML schema namespace as with alot of different libraries it can keep my XAML cleaner.  Is there any way to fix that beyond explictly referencing libraries in my XAML?

    Hi Stephen,

    It should appear either way. This error is now fixed and it is ok in the latest internal build. I would recommend you to wait for the official SP1 to be released and upgrade.
