Fire Datalist OnItemDataBound event on Dropdown SelectedIndexChanged

Question

是否可以在下拉列表中觸發Datalist的OnItemDataBound事件？SelectedIndexChanged ???
我想通過下面的代碼，但它什麼都不做：

protected void drpTopic_SelectedIndexChanged(object sender, EventArgs e) 
{ 
     dlSubjects.ItemDataBound +=new DataListItemEventHandler(dlSubjects_ItemDataBound); 
} 

protected void dlSubjects_ItemDataBound(object sender, DataListItemEventArgs e) 
{ 
     // Some Code... 
} 

請幫我解決這個問題...

在你SelectedIndexChange重新綁定您的數據列表，因爲它會自動閃光ItemDataBound事件
