i have set the watermark for autocompletebox by setting the WatermarkContent, property, it works
, however in the visual studio output window i can still see the following errors which i would like to avoid.
System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='RadWatermarkTextBox'
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=WatermarkTextBox'. BindingExpression:Path=ActualWidth; DataItem=null; target element is 'AutoCompleteBoxesWrapPanel' (Name=''); target property is 'Width' (type 'Double')
