Binding command to SelectionChanged Event

[Devika]

I have declared a combobox as below by attaching a command: But it is not working. But when I attach DropDownOpened event it works for me. Please help.

 

<telerikInput:RadComboBox Width="50" Height="20" app:RateTableViewModel.Command="{Binding Path=TelrikComboChange}" >

<ComboBoxItem Content="Balance"/>

<ComboBoxItem Content="Fee"/>

<ComboBoxItem Content="Age"/>

</telerikInput:RadComboBox>

And in the viewModel i have the commandPropertyChange as below:

private static void OnCommandChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

{

if (d is RadComboBox)

{

RadComboBox b = d as RadComboBox;

ICommand c = e.NewValue as ICommand;

b.SelectionChanged += delegate(object sender, Telerik.Windows.Controls.SelectionChangedEventArgs arg) { c.Execute(null); };

}

}



public ICommand TelrikComboChange

{

            get

            {



                return new RelayCommand(param => TelrikComboChange_Executed());

            }

        }

        void TelrikComboChange_Executed()

        {

            MessageBox.Show("Hello");

        }

Hi Devika,

I created a simple application that appears to be working on my side. I used the latest internal build assemblies. Am I missing something?

Thanks a lot Valeri.. i got the problem with my code. The problem was because i used ComboBoxItem instead of RadComboBoxItem.

Hi,

I am using the RadTreeView control. i am not able to use the command binding on the control. Let me know how can i implement the command binding on this control.

Thank you,
Deepthi.

Hello Deepthi,

RadTreeView does not support command binding since it is not a command source. I've added an item in our public issue tracking system called "TreeView: CommandBindings support" which will be available for tracking and voting tomorrow the latest. If this item gathers enough popularity we will definitely implement it.
