請嘗試下面的代碼片段。

讓我知道如果我不明白你的問題。

客戶端：

JS

function CheckToochSelection(a) { 
      alert(a); 
     } 

ASPX

<asp:Button ID="btnExplodedGroupCode" runat="server" CommandArgument='<%# Eval("Name") %>' 
      Text='<%# Eval("Name") %>' Width="75px" OnClientClick='<%# "return CheckToochSelection(" + Container.ItemIndex +");" %>' 
      CssClass="rg_button" OnClick="btnExplodedGroupCode_Click"/> 

服務器端：

protected void btnExplodedGroupCode_Click(object sender, EventArgs e) 
{ 
    int index = ((sender as Button).NamingContainer as DataListItem).ItemIndex; 
}
