[ASP.NET] 套用MasterPage的Button權限控管

說明：有使用MasterPage，想根據用戶的權限代號(Authority)管控頁面上的新增/編輯/刪除等button，無權限則disable該button。


做法：在MasterPage的PreRender事件中使用ContentPlaceHolder控制項的findcontrol找到新增/編輯/刪除等button後，再分別disable該button。例：

//namespace
[Flags]
public enum Privilege
{
            None=0,
            View=1,
            Add=2,
            Edit=4,
            Remove=8,
            All = None|View|Add|Edit|Remove
}

//xxx.master.cs
protected override void OnPreRender(EventArgs e)
{
        try
        {
             Button btnAdd = (Button)ContentPlaceHolder1.FindControl("btnAdd");
             Button btnEdit = (Button)ContentPlaceHolder1.FindControl("btnEdit");
             Button btnDel = (Button)ContentPlaceHolder1.FindControl("btnDel");

             if (Authority == (int)Privilege.View)
             {
                 btnAdd.Disable = false;
                 btnEdit.Disable = false;
                 btnDel.Disable = false;
             }
             else if (Authority == (int)(Privilege.View | Privilege.Add))
             {
                 btnEdit.Disable = false;
                 btnDel.Disable = false;
             }
             ...以此類推
        }
        catch (Exception ex)
        {
            throw ex;
        }
        base.OnPreRender(e);
}
