喜的朋友...
我在DataList显示图像。我在阿贾克斯模态弹出扩展开放代码隐藏文件的问题。
我写了下面的代码。

 DataListItem row = (DataListItem)(((ImageButton)e.CommandSource).NamingContainer);

            ImageButton ImageButton = (ImageButton)DataList1.Items[row.ItemIndex].FindControl("Image1") as ImageButton;

            Label lblnum = (Label)DataList1.Items[row.ItemIndex].FindControl("lblnum") as Label;

            AjaxControlToolkit.ModalPopupExtender modpopup = new AjaxControlToolkit.ModalPopupExtender();

            modpopup.TargetControlID = "ImageButton";

            modpopup.PopupControlID = "pnlDirImages";

            modpopup.BackgroundCssClass = "modalBackground";

            modpopup.CancelControlID = "btnclose";

            conn.Open();

            string strquery = "some query";

            SqlDataAdapter da = new SqlDataAdapter(strquery, conn);

            da.Fill(objds);

            conn.Close();

            if (objds.Tables[0].Rows.Count > 0)

            {

                dlImages.DataSource = objds.Tables[0];

                dlImages.DataBind();

                pnlDirImages.Visible = true;

                modpopup.Show();

            }

            else

            {

                pnlDirImages.Visible = false;

               

            }
