从GridView删除行

Question

I have an RadGridView . When users clicks on a row and then click my Delete button I call a method to delete that row from my database. But it shows this entry on the GridView . I can manually call the LoadGridView() method again to show the user that the entry has been deleted but isn't there any other built-in method that can remove that item from the GridView too?

Here is the Delete Click EventHandler:

private void OnDeleteClick(object sender, RoutedEventArgs e)
{
    Product deleteProduct = new Product();
    foreach (Product product in this.grdProductGrid.SelectedItems)
    {
        deleteProduct = product;
    }
    if (deleteProduct != null)
    {
        _service.DeleteProductAsync(deleteProduct);
        this.grdProductGrid.SelectedItems.Clear();
    }
}

The grid binding:

List<Product> productList = new List<Product>();
this.grdProductGrid.ItemsSource = productList;

Answer 1

Since you're using a List as a source, you need to remove the item from the list and manually force the RadGridView to refresh;

// Temporarily store the ItemSource as a List in tmp
List tmp = (List)this.grdProductGrid.ItemsSource; 

// Remove the item from the List
tmp.Remove(deleteP‌​roduct); 

// Force a refresh by "tricking" RadGridView 
// that it's getting an entirely new ItemsSource
this.grdProductGrid.ItemsSource = null; 
this.grdProductGrid.ItemsSource = tmp;
