Question

我想为我的crud按钮创建一个自定义控件。用户控件将具有以下代码。

 private void btnDelete_Click(object sender, EventArgs e)
    {      if (MessageBox.Show("Are you sure to Delete?", "Please Confirm", MessageBoxButtons.OKCancel) == DialogResult.OK)
    {
        DeleteClick(sender, e); // this will read the code from GUI delete button

        if (DeleteResult.Success) 
        {
            MessageBox.Show("This record is deleted successfully.");
        }
        else
        {
            MessageBox.Show("This record is deleted failed.");
        }
    }

}

我的GUI

private void adminUserController_DeleteClick(object sender, EventArgs e)
{
    Repository.Delete(user);
}

问题：
1）将DeleteResult布尔结果从GUI传递给用户控件的最佳方法是什么？如何为删除按钮创建一个可以被UI挂钩的事件？ 2）如果我将错误记录器代码放在用户控制按钮上，您认为好吗？

Answer 1

通过调用新方法（foo）替换adminUserController_DeleteClick中的调用

private DeleteResult foo(TypeOfUser user)
{
   return Repository.Delete(user);
}

并调用foo而不是adminUserController_DeleteClick

foo将返回所需的结果

用户控制按钮
