RadDataFilter - DataTemplate with muliple selection RadComboBox

[Birgit]

Hello 

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">
        <Grid.Resources>

            <DataTemplate x:Key="ComboBoxEditor">
                <telerik:RadComboBox SelectedValue="{Binding Value, Mode=TwoWay, FallbackValue=null}" AllowMultipleSelection="True"/>
            </DataTemplate>

            <local:EditorTemplateSelector x:Key="EditorTemplateSelector">
                <local:EditorTemplateSelector.EditorTemplateRules>
                    <local:EditorTemplateRule PropertyName="MainCategory" DataTemplate="{StaticResource ComboBoxEditor}" />
                </local:EditorTemplateSelector.EditorTemplateRules>
            </local:EditorTemplateSelector>
        </Grid.Resources>

    <telerik:RadDataFilter x:Name="radDataFilter"
                           Source="{Binding Items, ElementName=radGridView}"
                           EditorTemplateSelector="{StaticResource EditorTemplateSelector}">

    <telerik:RadGridView x:Name="radGridView" Grid.Row="1" Grid.Column="0"
                         GroupRenderMode="Nested"
                         ItemsSource="{Binding M<View}"
                         IsFilteringAllowed="False"
                         AutoGenerateColumns="False"
                         ShowGroupPanel="True"
                         IsReadOnly="True"
                         ShowSearchPanel="True">
        <telerik:RadGridView.Columns>
        ...
        </telerik:RadGridView.Columns>
    </telerik:RadGridView>
</Grid>

 

How to implement multi select RadComboBox with checkbox filter?

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.
