手动阻止 WPF DataGrid 中的新行

Question

美好的一天。如何以编程方式防止在数据网格中创建新行？例如：

private void SomeDataGridEvent()
   if (MyBoolConditionIsTrue())
      Prevent_Grid_Row_Creation_Logic
   else
     //Do Nothing. The new row is created

编辑1： 注意：CanUserDeleteRows 必须为 TRUE。用户可以添加行，但前提是某些条件为真。

你可以这样做：

AddingNewItem="DataGrid_AddingNewItem"

private void DataGrid_AddingNewItem(object sender, AddingNewItemEventArgs e)
{
    if (sender is DataGrid dg)
    {
        if (MyBoolConditionIsTrue())
        {
            dg.Items.Remove(e.NewItem);
        }
        else
        {
            //Do Nothing. The new row is created
        }
    }
}

或者

RowEditEnding="DataGrid_RowEditEnding"

private void DataGrid_RowEditEnding(object sender, DataGridRowEditEndingEventArgs e)
{
    if (MyBoolConditionIsTrue())
    {
        e.Cancel = true;
    }
    else
    {
        //Do Nothing. The new row is created
    }
}
