求助，动态生成checkbox ,viewstate的问题，

Question

<asp:datalist id="DistList" runat="server" >
 <ItemTemplate>
   <asp:datalist id="BuildList" runat="server"  >
     <ItemTemplate>
<asp:CheckBox ID="chkBld" AutoPostBack="True" Runat="server" Checked="True" EnableViewState="true"></asp:CheckBox>
      </ItemTemplate>
   </asp:datalist>
</ItemTemplate>
</asp:DataList>


private void DistList_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
{
System.Web.UI.WebControls.DataList BuildList;
BuildList = (DataList)e.Item.FindControl("BuildList");
BuildList.ItemCreated += new DataListItemEventHandler(BuildList_ItemCreated);
//...
} private void BuildList_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
CheckBox chkBld = (CheckBox)e.Item.FindControl("chkBld"); 
chkBld.CheckedChanged += new System.EventHandler(this.chkBld_CheckedChanged);
}} private void chkBld_CheckedChanged(object sender, System.EventArgs e)
{

CheckBox chb = (CheckBox)sender;
DataTable dt = new DataTable();      if( !chb.Checked )
{}
else{}
//...
}

动态生成 第二层datalist ,在第二层datalist里动态生成checkbox。
为什么chkBld_CheckedChanged 无法触发 ？  checkbox AutoPostBack="True"
是viewstate的问题？如果只有一层datalist的时候，checkbox的 viewstate能很好地得到，CheckedChanged也能很好地触发谢谢！100分

Answer 1

樣板列裏面無法觸發子控件事件，但是會觸發DistList_ItemCommand事件

Answer 2

没对ItemDataBound ，ItemDataCreated做研究，不是很清楚，所以犯了错误。
知道怎么回事了 
谢谢大家
BuildList_ItemDataBound -〉BuildList_ItemDataCreated就行了。

<asp:datalist  id="DistList"  runat="server"  >  
 <ItemTemplate>                          
     <asp:datalist  id="BuildList"  runat="server" >                                  
         <ItemTemplate>  
           <asp:CheckBox  ID="chkBld"  AutoPostBack="True"  Runat="server"  Checked="True"  EnableViewState="true"></asp:CheckBox>                                                  
           </ItemTemplate>  
     </asp:datalist>  
</ItemTemplate>  
</asp:DataList>  
                                                                                                 
                                                                                                 
private  void  DistList_ItemCreated(object  sender,  System.Web.UI.WebControls.DataListItemEventArgs  e)  
{  
           System.Web.UI.WebControls.DataList  BuildList;  
           BuildList  =  (DataList)e.Item.FindControl("BuildList");  
           BuildList.ItemCreated  +=  new  DataListItemEventHandler(BuildList_ItemCreated);  
                                   //...  
}              
 
private  void  BuildList_ItemCreated(object  sender,  System.Web.UI.WebControls.DataListItemEventArgs  e)  
{  
           if  (e.Item.ItemType  ==  ListItemType.Item    &brvbar;  &brvbar;  e.Item.ItemType  ==  ListItemType.AlternatingItem)  
           {  
                       CheckBox  chkBld  =  (CheckBox)e.Item.FindControl("chkBld");    
                       chkBld.CheckedChanged  +=  new  System.EventHandler(this.chkBld_CheckedChanged);  
}  
 
}                                      
 
private  void  chkBld_CheckedChanged(object  sender,  System.EventArgs  e)  
{  
                                     
           CheckBox  chb  =  (CheckBox)sender;  
           DataTable  dt  =  new  DataTable();  
 
           if(  !chb.Checked  )  
           {}  
           else{}  
                                   //...  
}  这样ok了
