<script language="c#" runat="server">
SqlConnection myconn;
public void Page_Load(object src,EventArgs e)
{
string myconnstring="server=10.130.242.24;Trusted_Connection=true;database=xfdatabase";
myconn=new SqlConnection(myconnstring);
myconn.Open();
if(!Page.IsPostBack)
{
BindDataList();
}
}ICollection CreateTable()
{
DataSet ds=new DataSet();
SqlDataAdapter myadapter_rep=new SqlDataAdapter("GetReport",myconn);
myadapter_rep.Fill(ds,"report");public void BindDataList()
{
source.DataSource=CreateTable();
source.DataBind();
}public void DataList_ItemCommand(object src,DataListCommandEventArgs e)
{
source.SelectedIndex=e.Item.ItemIndex;
BindDataList();
}
</script>
<asp:DataList ID="source" runat="server" OnItemCommand="DataList_ItemCommand" RepeatLayout="Table" Width="100%">
                        <itemtemplate> <span class="message"><img src="../images/dot17.gif" width="9" height="14">
                            <asp:HyperLink Text='<%# DataBinder.Eval(Container.DataItem,"zt") %>' NavigateUrl='<%# "shownews.aspx?newsid="+DataBinder.Eval(Container.DataItem,"newsid")+"&selection=" + Container.ItemIndex %>' Target="_blank" ID="link" runat="server"></asp:HyperLink>
                            <%# DataBinder.Eval(Container.DataItem,"showdate","{0:yyyyMMdd}") %>
                            <%
string spic;
                            //spic=DataBinder.Eval(ds.Tables["report"],"showdate");
%>
</span> </itemtemplate>
                        <selecteditemtemplate> <%# DataBinder.Eval(Container.DataItem,"zt") %><br>
                        </selecteditemtemplate>
                      </asp:DataList>
我现在要把这个值<%# DataBinder.Eval(Container.DataItem,"zt") %>赋给一个变量，怎么实现
