UI Rendering Issue

[Azharshah]

Hi Progress Telerik,

We are using RadAutoCompleteBox for WPF.

Sometimes, while searching with Text, it displays with improper UI.

It is happening very rarely or at least once in a day.

Please find the attachment.

Kindly suggest on this.

 

Below is the code used in xaml:

<tk:RadAutoCompleteBox
                        Name="CountryRadComboBox"
                        Grid.Column="1"
                        VerticalAlignment="Center"
                        DropDownItemTemplate="{StaticResource CountryNameTemplate}"
                        ItemsSource="{Binding CountryList}"
                        SearchText="{Binding CountryTextChanged, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                        SelectedItem="{Binding SelectedCountry, Mode=TwoWay, NotifyOnValidationError=True, UpdateSourceTrigger=PropertyChanged}"
                        SelectionMode="Single"
                        TextSearchMode="Contains"
                        TextSearchPath="Description">
      <tk:RadAutoCompleteBox.FilteringBehavior>
           <tk:AsyncFilteringBehavior />
      </tk:RadAutoCompleteBox.FilteringBehavior>
</tk:RadAutoCompleteBox>

 

Thanks and Regards,
