Как передать несколько значений через аргумент команды в Asp.net?

У меня есть ImageButton с атрибутом CommandArgument, который имеет несколько значений Eval. Когда я нажимаю один из них, я хочу передать значения в событие ImageButton2_Click, но он не работает, потому что аргументы команды равны нулю.

<div class="sag-re-icerik" id="icerik2" runat="server">Lorem ipsum dolor sit amet, consectetur commodo et convallis et, auctor viverra metus. Aenean pharetra, arcu nec viverra mollis, turpis neque feugiat massa, non dapibus neque nunc ac orci. </div>
    <div class="oy-verme">
        <div class="yildiz"><asp:ImageButton ID="ImageButton4" runat="server" Height="19px" ImageUrl="~/images/yildiz.png" onclick="ImageButton2_Click" Width="20px"  style="position: relative; top: 13px; left:6px; float:left;  "    commandArgument='<%#Eval("sdasdas") + ","+Eval("fafasfa") %>' /></div>
        <div class="yildiz"><asp:ImageButton ID="ImageButton5" runat="server" Height="19px" ImageUrl="~/images/yildiz.png" onclick="ImageButton5_Click" Width="20px"  style="position: relative; top: 13px; left:8px; float:left;" commandArgument='<%#Eval("row[0].ToString()") + ","+Eval("row[1].ToString()") %>'/></div>
        <div class="yildiz"><asp:ImageButton ID="ImageButton6" runat="server" Height="19px" ImageUrl="~/images/yildiz.png" onclick="ImageButton2_Click" Width="20px"  style="position: relative; top: 13px; left:10px ; float:left; " commandArgument='<%#Eval("row[0].ToString()") + ","+Eval("row[1].ToString()") %>' /></div>
        <div class="yildiz"><asp:ImageButton ID="ImageButton3" runat="server" Height="19px"  ImageUrl="~/images/yildiz.png" onclick="ImageButton2_Click" Width="20px" style="position: relative; top:13px; left:12px ; float:left;" commandArgument='<%#Eval("row[0].ToString()") + ","+Eval("row[1].ToString()") %>' /></div>
        <div class="yildiz"> <asp:ImageButton ID="ImageButton2" runat="server" Height="19px" ImageUrl="~/images/yildiz.png" onclick="ImageButton2_Click" Width="20px"  style="position: relative; top: 13px; left: 14px; float:left;" commandArgument='<%#Eval("row[0].ToString()") + ","+Eval("row[1].ToString()") %>' /></div>
        <div class="oy-sil"><img src="images/oy-sil.png" width="11" height="13" style="position: relative; top: 30px; " /></div>
    </div>
</div>

Это код:

protected void ImageButton2_Click(object sender, ImageClickEventArgs e)
{
    ImageButton objImage = (ImageButton)sender;

    string[] commandArgs = objImage.CommandArgument.ToString().Split(new char[] { ',' });
    string id = commandArgs[0];
    string text = commandArgs[1];


    //  string s= Imageid.UniqueID.ToString();
    //this.baslik2.Text = s;
}

CommandArgument='<%# "scrapid=" + Eval("ScrapId")+"&"+"UserId="+ Eval("UserId")%>'

CommandArgument='<%#Eval("ScrapId").Tostring()+ Eval("UserId")%>
