Hello,

I am using the RAD ComboBox to display a list of CLR objects. When a user begins typing in this ComboBox, I want the results in the list to filter based on what is typed. I believe that I have followed the code showed in the demo here: http://demos.telerik.com/silverlight/#ComboBox/Configurator

When I click the combo box, my records are appearing in the drop down as I'm expecting. When I being typing, the records are changing, so I assume some filtering is occuring. However, the results in the list do not appear filtered based on what I am typing. Here is my code:

<telerik:RadComboBox x:Name="myComboBox"  Width="184"
  DisplayMemberPath="FullName" SelectedValuePath="FullName"
  ItemsSource="{Binding People}"
  telerik:TextSearch.TextPath="FullName" IsFilteringEnabled="True"
  CanAutocompleteSelectItems="True" CanKeyboardNavigationSelectItems="True"
  IsEditable="True" OpenDropDownOnFocus="True"
  TextSearchMode="Contains" EmptyText="(please select)"                     
  SelectionChanged="myComboBox_SelectionChanged">
  <telerik:RadComboBox.ItemsPanel>
    <ItemsPanelTemplate>
      <VirtualizingStackPanel />
    </ItemsPanelTemplate>
  </telerik:RadComboBox.ItemsPanel>
</telerik:RadComboBox>

What am I doing wrong? Why is my filtering not behaving as expected?

Thank you!

Hi Bill,

Unfortunately, these two features (filtering and virtualization) do not work together yet. We are aware of the problem and we will do our best to provide a fix in the near future, but I cannot give an estimate at this moment.

Please let us know if you have any other questions about our controls.

We are experiencing the same problem as well.  Is this slated to be fixed for the upcoming release or do we have to wait for a future release?  Also, do you have any recommendations for a workaround in the meantime so we can use the virtualization with the filtering?

Thanks,

Hello Jarred,

We do not have a certain timeframe yet, when this issue is going to be fixed. You can track the roadmap of our products to see if this is going to be implemented in the next release.
Unfortunately, due to limitations in the filtering of the ComboBox there is no workaround for using both - the virtualization and the filtering - together.
Sorry for the caused inconvenience.

Please let us know if you have any other questions about our controls.

Best wishes,
