Hi,

I would like to build my own member selector using an editable combobox and an autocompletion behaviour.

Is this possible?

Hello NOC NOC,

We have a similar feature request. It is more general than your require, but I think that it covers your need as well. Vote for it here if you want to raise its priority.

All the best,

Hi!
Is there an update on this?
Our customer wants to have a typeAHeadCombobox instead of a Combobox as Member Drop down.

Hello,

In order to achieve the desired behavior, you can predefine the control template of the FilterControl element and set the IsEditable property of the PART_SimpleFilterMemberComboBox RadComboBox to True.

Here's the extracted style for the Windows8 theme:

<Style TargetType="{x:Type DataFilter:FilterControl}" BasedOn="{StaticResource FilterControlStyle}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataFilter:FilterControl}">
                <Border x:Name="OuterBorder" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
                    <StackPanel Orientation="Horizontal">
                        <telerik:RadButton x:Name="PART_RemoveFilterButton" Command="{Binding RemoveFilter}" Style="{StaticResource RemoveFilterButtonStyle}"/>
                        <StackPanel Orientation="Horizontal" Visibility="{Binding IsComposite, Converter={StaticResource BooleanToVisibilityConverter}}">
                            <telerik:RadToggleButton
                Name="PART_CompositeFilterLogicalOperatorToggleButton"
                Style="{StaticResource ToggleFilterButtonStyle}"
                IsChecked="{Binding CompositeFilter.LogicalOperator, Mode=TwoWay, Converter={StaticResource LogicalOperatorToCheckedConverter}}"
                Content="{Binding CompositeFilter.LogicalOperator, Converter={StaticResource LogicalOperatorConverter}}"/>
                            <telerik:RadButton x:Name="PART_AddFilterButton" Command="{Binding AddFilter}" Style="{StaticResource AddFilterButtonStyle}"/>
                        </StackPanel>
                        <StackPanel Orientation="Horizontal" Visibility="{Binding IsComposite, Converter={StaticResource InvertedBooleanToVisibilityConverter}}">
                            <telerik:RadComboBox
                Name="PART_SimpleFilterMemberComboBox"
                Margin="0,0,2,0"
                                IsEditable="True"
                                IsTextSearchEnabled="True"
                VerticalAlignment="Center"
                ItemsSource="{Binding SimpleFilter.AvailableMembers}"
                SelectedItem="{Binding SimpleFilter.SelectedMember, Mode=TwoWay}"
                MinWidth="100"/>
                            <telerik:RadComboBox
                Name="PART_SimpleFilterOperatorComboBox"
                Margin="0,0,2,0"
                VerticalAlignment="Center"
                ItemsSource="{Binding SimpleFilter.AvailableOperators}"
                SelectedItem="{Binding SimpleFilter.Operator, Mode=TwoWay, Converter={StaticResource FilterOperatorToSelectedItemConverter}}"
                IsEnabled="{Binding SimpleFilter.Member, Converter={StaticResource FilterMemberToEnabledConverter}}"
                ItemTemplate="{StaticResource FilterOperatorTemplate}"
                MinWidth="100"/>
                            <DataFilter:FilterEditor
                DataContext="{Binding SimpleFilter}"
                ItemPropertyDefinition="{Binding SelectedMember}"
                FilterOperator="{Binding Operator}"
                HorizontalContentAlignment="Stretch"
                IsTabStop="False"
                VerticalContentAlignment="Stretch"
                MinHeight="22"/>
                            <Border Width="8" BorderBrush="Transparent" Visibility="{Binding CanUserCreateCompositeFilters, Converter={StaticResource InvertedBooleanToVisibilityConverter}}"/>
                            <telerik:RadButton x:Name="PART_ToCompositeFilterButton"
                Command="{Binding ToCompositeFilter}"
                Style="{StaticResource AddFilterButtonStyle}"
                Visibility="{Binding CanUserCreateCompositeFilters, Converter={StaticResource BooleanToVisibilityConverter}}"/>
                        </StackPanel>
                    </StackPanel>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="BorderBrush" Value="Transparent"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Padding" Value="0"/>
    <Setter Property="IsTabStop" Value="False"/>
    <Setter Property="SnapsToDevicePixels" Value="True"/>
    <Setter Property="VerticalAlignment" Value="Top"/>
    <Setter Property="HorizontalAlignment" Value="Left"/>
</Style>

Bear in mind that you need to add the following namespace:

xmlns:DataFilter="clr-namespace:Telerik.Windows.Controls.Data.DataFilter;assembly=Telerik.Windows.Controls.Data"
