从两个不同的页面获取数据

Question

这是我的问题。举例来说，当我点击转发器行 ID 时，它将转移到特定客户的发票。

但是在客户发票页面，它只有在客户ID登录时才会打开。所以这里是两个不同的页面访问一页数据。我的代码如下。在转发器的页面中。

     <th>
      <asp:LinkButton ID ="lnkbtnStmt" Text ="Statement" OnClick ="lnkbtnStmt_Click" runat="server"></asp:LinkButton>
      <asp:HiddenField ID ="hfStmt" runat ="server" Value='<% #Eval("No")%>'/>
     </th>

在转发器 .cs 页面中：

    public void lnkbtnStmt_Click(object sender, EventArgs e) 
    {
        int rptIndex = ((RepeaterItem)((LinkButton)sender).NamingContainer).ItemIndex;
        string hfItem = Convert.ToString(((HiddenField)RptEmpCustInvoise.Items[rptIndex].FindControl("hfStmt")).Value);

        Customer_Ledger_Entries custlist = new Customer_Ledger_Entries();
        List<Customer_Ledger_Entries_Filter> cFilter = new List<Customer_Ledger_Entries_Filter>();
        Customer_Ledger_Entries_Filter cfield = new Customer_Ledger_Entries_Filter();
        cfield.Field = Customer_Ledger_Entries_Fields.Customer_No;
        cfield.Criteria = hfItem;
        cFilter.Add(cfield);
        Customer_Ledger_Entries[] culist = cls.wsCustInvoice.ReadMultiple(cFilter.ToArray(), null, 1);
        if (culist.Length > 0) 
        {
            Response.Redirect("frmCustomerInvoice.aspx?Customer_No=" + hfItem);
        }
    }

并在另一个客户页面中。

    protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            if (!IsPostBack)
            {
                GetOpeningBal();
                bindCustInvoice(objSession.getSession(HttpContext.Current, "NonEmpCode"));
                string empCustId = Request.QueryString["Customer_No"];
                if (empCustId.Length != 0)
                {
                    CustInvoice("empCustId");
                }
                GetClosingBal();

            }
        }
        catch (Exception ex)
        {
            ScriptManager.RegisterStartupScript(this.Page, this.GetType(), string.Empty, "alert('" + ex.Message.ToString() + "');", true);
        }
    }

在此页面中，bindCustInvoice() 方法在客户登录时起作用，CustInvoice("empCustId"); 方法在我们单击转发器 ID 时起作用。谁能给我解决方案？

当您单击 Repeater Id 时，尝试从查询字符串发送页面名称。并检查您的另一个客户页面中的页面名称

伪代码

 string PageName ="";
      if(Request.QueryString["PageName"] != null)
      {
       PageName= Request.QueryString["PageName"];
      }


    if(PageName != "")
    {
     string empCustId = Request.QueryString["Customer_No"];
                    if (empCustId.Length != 0)
                    {
                        CustInvoice("empCustId");
                    }
    }
    else{
      bindCustInvoice(objSession.getSession(HttpContext.Current, "NonEmpCode"));
    }
