Radcombo box selected index?

[sivakanth]

Hello Telerik Team,
                             I have one clarification in my latest WPF project.Here I am  having one radcombo box.Its contains 3 values.

<telerik:RadComboBox HorizontalAlignment="Left" SelectedIndex="{Binding xx}"  Margin="114,207,0,0" Name="radComboBox2" VerticalAlignment="Top" Width="205">
            <telerik:RadComboBoxItem Content="Item 1" />
            <telerik:RadComboBoxItem Content="Item 2" />
            <telerik:RadComboBoxItem Content="Item 3" />
        </telerik:RadComboBox>

When window loading time i want to display item3 in radcombobox.After window loading client can change the value and storing into database.
So i am binding into selectedindex in XAML.
codebehind sample

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.radComboBox2.SelectedIndex = 2;
        }
    }

 But it display empty Combobox?
why?
pls give me any suggestions

Hi Sivakanth,

Your code looks fine and there shouldn't be any problems. Just set the Mode of the binding to TwoWay and that should be enough to fix the issue.

Please let us know if that helped.

Hi Sivakanth,

In that case could you please send us your project in which this issue can be reproduced. Also, could you please share with us which version of the controls you are using? Could you please try with the latest assemblies and let us know if the issue persists.

Best wishes,
