Text search problem

[Miłosz Cechnicki]

Hi,
I have a problem with Text search function in a ComboBox control.

The definition of the RadComboBox control, that does not support text search:
<telerikInput:RadComboBox x:Name="ctrlForm" SelectionChanged="ctrlForm_SelectionChanged" IsTextSearchEnabled="True">
                <telerikInput:RadComboBox.ItemTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding Form, Converter={StaticResource FormFieldConverter}}"/>
                    </DataTemplate>
                </telerikInput:RadComboBox.ItemTemplate>
            </telerikInput:RadComboBox>

However, very similiar definition is working properly:
<telerikInput:RadComboBox x:Name="ctrlForm" SelectionChanged="ctrlForm_SelectionChanged" IsTextSearchEnabled="True">
                <telerikInput:RadComboBox.ItemTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding .,}"/>
                    </DataTemplate>
                </telerikInput:RadComboBox.ItemTemplate>
            </telerikInput:RadComboBox>

Also binding to a property without using converter does not allow to use search.

Hello Miłosz,

TextSearch uses the DisplayMemberPath to determine which property should be used as Text. When you use ItemTemplate you should specify the Text property with the telerik:TextSearch.TextPath attached property, where the telerik namespace is declared as:

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

Do you have any simple sample code showing how to implement this.  I'm confused how to use Attached properties.  Will this also work if both ItemTemplate and SelectionBoxTemplate are set.

Hello Jared,

Here is a online example, that demonstrates the different combinations of TextSearch.TextPath and ItemTemplate:
