    I have tried a RadDataFilter with RadComboBox as DataTemplate.

    Is work's fine, but when i allow muliple Selection, the filter does not work as I expect (Only one value is filtered).

    How do I have to make this work?


    <Grid Margin="20">
                <DataTemplate x:Key="ComboBoxEditor">
                    <telerik:RadComboBox SelectedValue="{Binding Value, Mode=TwoWay, FallbackValue=null}" AllowMultipleSelection="True"/>
                <local:EditorTemplateSelector x:Key="EditorTemplateSelector">
                        <local:EditorTemplateRule PropertyName="MainCategory" DataTemplate="{StaticResource ComboBoxEditor}" />
        <telerik:RadDataFilter x:Name="radDataFilter"
                               Source="{Binding Items, ElementName=radGridView}"
                               EditorTemplateSelector="{StaticResource EditorTemplateSelector}">       
        <telerik:RadGridView x:Name="radGridView" Grid.Row="1" Grid.Column="0"
                             ItemsSource="{Binding M<View}"


    How to implement multi select RadComboBox with checkbox filter?


    Thanks in advance for any help

    Is it common for the people of Telerik not to answer? I

    assume no answer means that it is not possible.

    Hello Birgit,

    I have replied you in the support thread that you opened regarding this requirement. As stated in it, I am researching whether such behavior can be achieved, but I need a little more time for this. I will update this thread with my findings as well, but I would kindly ask you to continue our communication in the support thread, so that double posting is avoided.

    Thank you for understanding.
