我一直在尋找一個非常令人沮喪的問題。起初，RowDataBound事件在重寫整個gridview之後並沒有觸發它的排序事件。這次它抱怨沒有註冊該事件的處理程序。這是個謊言！！！！！！！！ 我已經嘗試了很多東西，而且我在這一點上絕望，我真的不知道發生了什麼。任何幫助將不勝感激。GridView事件不能正常工作

var PLEASE_WORK = true;
}

爲了避免進一步的重視第三方控制我改回GridView的到正規的ASP之一。 這就是現在的結構。 ...... 注意：沒有足夠的信譽來添加鏈接:(
FYI - 一個'SortableGridView'是不一樣的控制作爲ASP'GridView'。 –
NeverMind SortableGridView。這是我創建的一個控件，爲了這個目的它可以完全替換爲一個常規的gridview。 – Oxnigarth
事實上，這個錯誤是從一個常規的asp GridView開始的，我試圖用我自己的組件來替換它，看它是否有任何區別，它沒有。 – Oxnigarth
