[Solved] TextSearchPath and DisplayMemberPath differences?

[Manuel]

Hi,

I have a problem when setting my DisplayMemberPath:

<t:RadAutoCompleteBox x:Name="AutoCompleteBox" Grid.Row="2" Grid.ColumnSpan="3"
                                         ItemsSource="{Binding Suggests}"
                                        SearchText="{Binding TextSearch, Mode=TwoWay}"
                                        SelectedItem="{Binding SelectedSuggest, Mode=TwoWay}"
                                    TextSearchPath="SearchPath" DisplayMemberPath="Name">
                <t:RadAutoCompleteBox.DropDownItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding Name}" />
                            <TextBlock Text=" - " />
                            <TextBlock Text="{Binding Code}" />
                        </StackPanel>
                    </DataTemplate>
                </t:RadAutoCompleteBox.DropDownItemTemplate>
            </t:RadAutoCompleteBox>

In the code above, all is working fine, except that when i have selected an item, the text displayed is the one in my SearchPath property, and not the one in my Name property.
What did i do wrong?

Hello Manuel,

We tested the provided code snippet of with the latest version of Telerik controls (2014.3.1202) and everything works as expected - the DisplayMemberPath gets visualized when item is selected. The TextSeachPath property is used for the filtering of the items while the DisplayMemberPath contains the property that will be displayed as soon as an item is selected. However, this is only valid if the SelectionMode property is set to Multiple (which is by default). If it is set to Single the property that will be visualized when a selection is made will be the one that is set to the TextSearchPath.

What we could recommend you is to upgrade to the latest version of the controls if you're using an older one.

We hope this will help you.

Hello,

I understand what happened so.

I need to use single selection mode.
There is a way to handle the feature with single selection mode?

Hello Manuel,

As you are using Single SelectionMode I suggest creating a custom FilteringBehavior and overriding its FindMatcingItems method in order to implement a custom filtering by a different property of the objects.
You can supply the TextSearchPath in the custom FilteringBehavior. This way you don't have to supply it in xaml and the DisplayMemberPath will be used to visualize the SelectedItem.

Please find attached a sample project demonstrating this approach.
Hopefully this helps and is suitable for your scenario.
