父页面与子页面传值

父页面与子页面

1.父页面调用子页面

    protected void Button4_Click(object sender, EventArgs e)
    {
      this.RegisterClientScriptBlock("ph", "<script> window.open('../popup/ShowTransferForm.aspx','','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=yes,width=700,height=350')</script>");  
      return;
    }

 

2.子页面选定按钮 利用session传值 父页面刷新

    protected void Button1_Click(object sender, EventArgs e)
    {
        // this.RegisterClientScriptBlock("sss", "<script>window.opener.ss();</script>");
        Session["TranFormNum"] = "ssss";
        Response.Write("<script>window.opener.location.href='../Stock/TransferForm.aspx?treepar=006'</script>");
        Response.Write("<script>window.close();</script>");
    }

3.父页面验定子页面所传递的session信息

        //子窗口传递值　刷新绑定表格
        if (Session["TranFormNum"] != null && Session["TranFormNum"].ToString().Trim() != "")
        {
            ViewState["TranFormNum"] = Session["TranFormNum"].ToString().Trim();
            txtDay.Text = ViewState["TranFormNum"].ToString().Trim();
        }
