C＃WPF DataGrid刪除每個選定的項目

Question

我有一個數據網格，在xaml中被稱為“DataGridUsers”我想刪除所選的值，但我該怎么做？

這是我的代碼

    private void BtnDelete_Click(object sender, RoutedEventArgs e)
    {
        if (DataGridUsers.SelectedItem == null)
        {
            MessageBox.Show("There is no selected rows!");// show a message here to inform
        }
        else
        {
            foreach (DataGrid item in DataGridUsers.SelectedItems)
            {
                DataGridUsers.Items.Remove(item);
            }
        }
    }

Answer 1

使用SelectedIndex

while (DataGridUsers.SelectedItems.Count > 0){
  DataGridUsers.Items.RemoveAt(DataGridUsers.SelectedIndex);
}

Answer 2

試試這個：

private void BtnDelete_Click(object sender, RoutedEventArgs e)
{
    if (DataGridUsers.SelectedItem == null)
    {
        MessageBox.Show("There is no selected rows!");// show a message here to inform
    }
    else
    {
        DataView dataView = DataGridUsers.ItemsSource as DataView;
        if (dataView != null)
        {
            for (int i = DataGridUsers.SelectedItems.Count - 1; i >= 0; i--)
            {
                DataRowView drv = DataGridUsers.SelectedItems[i] as DataRowView;
                if (drv != null)
                {
                    dataView.Table.Rows.Remove(drv.Row);
                }
            }
        }
    }
}
