I have a Multi Column Drop Down control which is working, except when there are no items in the drop down list (which is normal), the display text doesn't clear out. How can I fix it?
Thanks
<syncfusion:SfMultiColumnDropDownControl x:Name="CasesList" Margin="5,3" Width="300" Height="22"
VerticalAlignment="Center" AllowAutoComplete="True" ReadOnly="True"
AutoGenerateColumns="False" ItemsSource="{Binding CaseListSource,Mode=TwoWay}" PopupWidth="500"
SelectedItem="{Binding SelectedCaseLookup,Mode=TwoWay}"
DisplayMember="DisplayValue" ValueMember="DisplayValue" >
<syncfusion:SfMultiColumnDropDownControl.Columns>
<syncfusion:GridTextColumn MappingName="CaseNumber" HeaderText="Case Number" Width="100" />
<syncfusion:GridTextColumn MappingName="LookupValue" HeaderText="Non-Compliance" Width="220" />
<syncfusion:GridTextColumn MappingName="CaseDate" HeaderText="Date" Width="150" />
</syncfusion:SfMultiColumnDropDownControl.Columns
</syncfusion:SfMultiColumnDropDownControl>
