Question

How can I save all data from my DataGrid when my button save is clicked?

This is my code and say error:

string value = (new System.Collections.Generic.Mscorlib_CollectionDebugView<SampleCrudApp.MainPage.GenerateNumber>(grdOrders.ItemsSource)).Items[0].items1;

Answer 1

Try this

 private void btnSave_Click(object sender, EventArgs e)
    {
        //get data back from the datagrid view
        //assuming my gridview is bound to ObservableCollection<User>
        var users= dataGridView1.DataSource as ObservableCollection<User>;
        foreach (var user in users)
        {
            //perform the save
        }

    }
