I am updating my ItemsSource on key down event. But this is removing the text I have entered. Please let me know how to solve this?
[CODE]
<syncGrid:SfMultiColumnDropDownControl AllowAutoComplete="True"
AllowIncrementalFiltering="True" AutoGenerateColumns="False"
AllowImmediatePopup="True" AllowNullInput="True"
DisplayMember="Name"
x:Name="AutocompleteMultiselect"
ValueMember="ApplicationID"
Grid.Column="2" Grid.Row="0"
ItemsSource="{Binding Path=SearchResults}"
Height="30" Width="400"
Text="{Binding SearchText}"
>
<syncGrid:SfMultiColumnDropDownControl.Columns>
<syncGrid:GridTemplateColumn HeaderText="Icon" Width="80">
<syncGrid:GridTemplateColumn.CellTemplate>
<DataTemplate>
<Image Source="ms-appx:///Assets/Icon_Male.png" Stretch="Uniform" Margin="5" Width="12" />
</DataTemplate>
</syncGrid:GridTemplateColumn.CellTemplate>
</syncGrid:GridTemplateColumn>
<syncGrid:GridTextColumn HeaderText="Id" Width="120" MappingName="ApplicationID" />
<syncGrid:GridTextColumn HeaderText="Name" Width="250" MappingName="Name" />
</syncGrid:SfMultiColumnDropDownControl.Columns>
<Interactivity:Interaction.Behaviors>
<Core:EventTriggerBehavior EventName="KeyDown">
<Core:InvokeCommandAction Command="{Binding UserSelectionChangedCommand}"
CommandParameter="{Binding SearchText,ElementName=AutocompleteMultiselect}" />
</Core:EventTriggerBehavior>
