>Dear All,
>
>I am trying to retrieve the value of a DataList cell in a label and  assign
>it to a Session Variable. For this purpose I am using a method :
>
>private void OpenForm(object aDate,object aScore,DataListCommandEventArgs f)
>
>{
>
>aDate=(((Label)f.Item.FindControl("lblActivityDate")).Text);
>aScore= (((Label)f.Item.FindControl("lblActivityScore")).Text);
>string scriptblock = "<script
>language='javascript'>window.open('ABC.aspx'_blank','width='+700+',height='+610+',top=0,left=0,scrollbars=1,menubar=no,toolbar=no,location=no');</script>";
> Page.RegisterStartupScript("OpenPrintWindow", scriptblock);
>
>}
>
>But when I use this method
>
>protected void dgdActivities_ItemCommand(Object s,DataListCommandEventArgs e)
>
>{
>
>if(e.CommandName=="Print")
>
>{
>
>        OpenForm(Session["BDate"],Session["BScore"],e);
>
>}
>
>}
>
>the variables  Session["BDate"] and Session["BScore"] are empty. Because
>when I use Session["BDate"]  and Session["BScore"]  on some other Web forms
>it throws the following error
>
>Object reference not set to an instance of an object
>
>the variables  Session["BDate"] and Session["BScore"] are empty.

>Any help would be greatly appreciated. Below is my sample HTML code:
>
><ItemTemplate>
>
><tr align="center">
>       <td>
>        <asp:Label ID="lblActivityName"
>Text='<%#DataBinder.Eval(Container.DataItem,"ActivityName")%>' Runat="server">
>        </asp:Label></td>
>       <td>
>        <asp:Label ID="lblActivityDate"
>Text='<%#DataBinder.Eval(Container.DataItem,"ActivityDate","{0:d}")%>'
>Runat="server">
>        </asp:Label></td>
>       <td>
>        <asp:Label ID="lblActivityScore"
>Text='<%#DataBinder.Eval(Container.DataItem,"Score")%>' Runat="server">
>        </asp:Label></td>
>       <td>
>        <asp:Button ID="btnPrintCertificate" Text="Print"
>CommandName="Print" Runat="server"></asp:Button></td>
>      </tr>
