Fire Datalist OnItemDataBound event on Dropdown SelectedIndexChanged

Question

是否可以在下拉列表中触发Datalist的OnItemDataBound事件？SelectedIndexChanged ???
我想通过下面的代码，但它什么都不做：

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

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

请帮我解决这个问题...

在你SelectedIndexChange重新绑定您的数据列表，因为它会自动闪光ItemDataBound事件
