Databindings Incorrect

[Darren]

Hi,

I am dynamically filling a RadComboBox based on input from the keyboard.  My XAML looks like this:

        <telerikInput:RadComboBox x:Name="MedName" GotFocus="MedName_GotFocus" SelectionChanged="MedName_SelectionChanged" ItemsSource="{Binding IdentifierNameType}" Text="{Binding Name, Mode=TwoWay}" Grid.Row="1"  Grid.Column="1" IsTextSearchEnabled="False" IsEditable="True" Height="20" Width="200" HorizontalAlignment="Left">
            <telerikInput:RadComboBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock Text="{Binding Name}" />
                    </StackPanel>
                </DataTemplate>
            </telerikInput:RadComboBox.ItemTemplate>
        </telerikInput:RadComboBox>

My IdentifierNameType class looks like this:

        public class IdentifierNameType
        {
            private int identifier = 0;
            private string name = "";

            public IdentifierNameType() { }

            public IdentifierNameType(int identifier, string name)
            {
                this.identifier = identifier;
                this.name = name;
            }

            [DataMember(Name = "Identifier")]
            public int Identifier
            {
                get
                {
                    return this.identifier;
                }
                set
                {
                    this.identifier = value;
                }
            }

            [DataMember(Name = "Name")]
            public string Name
            {
                get
                {
                    return this.name;
                }
                set
                {
                    this.name = value;
                }
            }
        }

Everything looks good except for when I actually select an item from the dropdown.  It looks like my bindings are wrong.  How do I set it to where the IdentifierNameType.Name is bound correctly?  What I am seeing in the text portion of the RadComboBox is the class name.

Thanks,
Darren

Hi Darren ,

Instead of binding the RadComboBox.Text property you need to set the TextSearch.TextPath property:
<telerikInput:RadComboBox telerik:TextSearch.TextPath="Name" ... />

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

I am not sure about the binding on the Text property, but unless you bind it to the data context, you will no longer need it, because it is unrelated to the problem.

Hi Valeri,

When I try that I get an error that tells me the attachable property is not found.

Thanks,

Hello Darren ,

Did you add the following line:
xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"

in your XAML? The final result should look something like this:
<UserControl x:Class="SilverlightApplication1.SilverlightControl3"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
  xmlns:telerikInput="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input">
 <Grid x:Name="LayoutRoot" Background="White">
  <telerikInput:RadComboBox telerik:TextSearch.TextPath="Name" ... />
 </Grid>
</UserControl>
