Hi,

I am unable to find "Command" property in designer while trying to set it for "Button" control.

I am trying to do this in Silverlight targetting Framework 3, and has not added any special reference as such. Am I missing anything here? However, I have added reference to the DLL where I have created a class implemented from ICommand intereface.

Any help on this, much appreciated.

Commands not being Invoked in my View Model Class.

Hi , I am developing an MVVM Application. I am following the above method u sugggested.

I have a listBox showing all the Employee Names and beside it is the details of every employee.

On click of a diffrent employee from the listBox we get the details of the Next Employee.

I have also kept 4 Commands . But i am not sure why my commands in the VM is not getting called on click from View.

--VIEW CLASS-------------------------------------------------------------------

                 ItemsSource="{Binding Path=MinerList, Mode=TwoWay}"
                 SelectedItem="{Binding Path=SelectedMiner, Mode=TwoWay}" >

                  DataContext="{Binding Path=SelectedMiner, Mode=TwoWay}"
                      Margin="5" Background="LightGray">









                    ......

                .....

...

--VIEW MODEL CLASS----------------------------------------------------------------------------------------------------------

public ICommand SaveCommand { get; set; }

In Constructor...

public MinerMasterVM()
        {
            SaveCommand = new DelegateCommand(SaveMiner, CanSaveMiner);
            MinerServiceClient msClient = new MinerServiceClient();
            msClient.GetMinersCompleted += new EventHandler(msClient_GetMinersCompleted);
            msClient.GetMinersAsync();
        }

public void SaveMiner(object parameter)
        {
            ....
        }

        void msClient_UpdateMinerCompleted(object sender, UpdateMinerCompletedEventArgs e)
        {
            throw new NotImplementedException();
        }

        private bool CanSaveMiner(object parameter)
        {
            return true;
        }

-----------------------------------------------------------------------------------------------------

I am calling the View XMAL file from the MainPage.XMAL.

views:MinerView x:Name="MinerDataView">

MinerMasterVM mVM = new MinerMasterVM();

MinerDataView.DataContext = mVM;

All my VM objects are accessible . But not the Commands .

Not sure Why . Can some body through some light on it.

Regards

Debashish

This is cool. I've been meaning to look into MVVM for a while now. One thing I've often wondered. How are errors handled? In your above code snippits, what happens if the save command throws an error? How is that sent back to the user so they can correct any mistakes and try again?
