从GridView中删除行

Question

我有RadGridView。当用户点击row然后点击我的Delete按钮时，我会调用一种方法从我的数据库中删除该行。但它在GridView上显示了此条目。我可以再次手动调用LoadGridView()方法向用户显示该条目已被删除但是没有任何其他内置方法可以从GridView中删除该项目吗？

这是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();
    }
}

网格绑定：

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

Answer 1

由于您使用List作为来源，因此您需要从列表中删除该项并手动强制RadGridView进行刷新;

// 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;
