[Solved] Delete row

[Denis]

Hi!
I am using this code:

public OraDomainContext ctx = new OraDomainContext();

        public MainPage()

        {

            InitializeComponent();

            LoadOperation<People> LoadOperation = ctx.Load(ctx.GetPeoplesQuery());

            LoadOperation.Completed += new EventHandler(LoadOperation_Completed);

        }

 

        void LoadOperation_Completed(object sender, EventArgs e)

        {

            radGridView1.ItemsSource = ctx.Peoples;

        }

 

        private void button1_Click(object sender, RoutedEventArgs e)

        {

            ctx.Peoples.Remove(radGridView1.SelectedItem as People);

            ctx.SubmitChanges();

        }


When this code execute it shows that row is deleted, but when i refresh page then i can see that row again. Please help me

Hello Denis,

 Can you please confirm that when the actual remove operation is done your Peoples collection is correctly populated? If the collection is not populated on time your delete might not correctly propagate to the server.
Please put a break point here:

ctx.Peoples.Remove(radGridView1.SelectedItem as People);

and assure that the peoples collection is not empty.

I checked that - peoples collection is not empty.
In the console project deleting is executed, but in the Silverlight application is not.
The problem in the RIA Services?

Hello Denis,

 Basically the peoples collection is loaded asynchronously. The only problem I can see here is if the delete occurs before the collection has been loaded. This would result in removing the entry from the grid but not from the database. Are you sure that this is not the case here? 

Kind regards,
