从gridview内部的LinkBut​​ton传递值 [英] Passing values from a LinkButton inside a gridview

问题描述

早安们

我在gridview中有一个linkbutton，该linkbutton假设正在执行2个工作，第一个它应该执行一个modalpopup，第二个它应该能够将值传递给弹出窗口中的控件

它执行的唯一操作是执行弹出窗口.以下是我的链接按钮

Morning guys

I have a linkbutton inside my gridview, the linkbutton suppose to be doing 2 jobs, 1st it should execute a modalpopup and 2ndly it should be able to pass values to the controls inside the popup

The only thing it performs is to execute the popup. Below is my linkbutton

<asp:LinkButton  ID="createAppointment" runat="server"  PostBackUrl='<%#"frmFindAppointment.aspx?Fullname=" + HttpUtility.UrlEncode(Eval("Fullname").ToString())+"&RecordNumber="+ HttpUtility.UrlEncode(Eval("RecordNumber").ToString())+"&Date="+  HttpUtility.UrlEncode(Eval("Date").ToString())+"&SlotID="+ HttpUtility.UrlEncode(Eval("SlotID").ToString())+"&Timeslot="+ HttpUtility.UrlEncode(Eval("Timeslot").ToString())+"&EmpEmail="+ HttpUtility.UrlEncode(Eval("EmpEmail").ToString())  %>' Text="Create Appointment" />

以下是我如何接收传递的值

Below is how i recieve my passed values

if (Request.QueryString["Fullname"] != null && !string.IsNullOrEmpty(Request.QueryString["Fullname"].ToString()) || (Request.QueryString["RecordNumber"] != null && !string.IsNullOrEmpty(Request.QueryString["RecordNumber"].ToString()) || (Request.QueryString["EmpEmail"] != null && !string.IsNullOrEmpty(Request.QueryString["EmpEmail"].ToString()) ||
                (Request.QueryString["Date"] != null && !string.IsNullOrEmpty(Request.QueryString["Date"].ToString())) || (Request.QueryString["SlotID"] != null && !string.IsNullOrEmpty(Request.QueryString["SlotID"].ToString())) || (Request.QueryString["Timeslot"] != null && !string.IsNullOrEmpty(Request.QueryString["Timeslot"].ToString())))))
                {
                    string fullName = Convert.ToString((Request.QueryString["FullName"]));
                    Session["FullName"] = fullName;
                    this.txtViewStaffName.Text = Session["FullName"].ToString();


                    recNumber = Convert.ToInt32(Request.QueryString["RecordNumber"].ToString());

                    date = Request.QueryString["Date"].ToString();

                    slot = Convert.ToInt32(Request.QueryString["SlotID"].ToString());
                    Session["SlotID"] = slot;

                    this.ddlTimeSlots.Items.Add(Request.QueryString["Timeslot"].ToString());

                    Session["EmpEmail"] = (Request.QueryString["EmpEmail"].ToString());


                }

现在我看到值是NULL，因为跳过了if语句.我需要帮助.

Now i see that the values are NULL because the if statement is skiped. I need help.

推荐答案

尝试使用Gridview的Row Command Event，使您的链接按钮像这样

Hi,
Try using Gridview''s Row Command Event, make your link button like this

<asp:LinkButton  ID="createAppointment" runat="server" CommandArgument="<"FullName">" Text="Create Appointment" commandname="abc" /> 

和
在代码上写这个

if(e.CommandName ="abc")
//做您想做的事

and
on code write this

if(e.CommandName="abc")
//do what you want

如果条件如下所示，请尝试更改

try changing if condition like below

if (
                (Request.QueryString["Fullname"] != null && !string.IsNullOrEmpty(Request.QueryString["Fullname"].ToString()))
                ||
                (Request.QueryString["RecordNumber"] != null && !string.IsNullOrEmpty(Request.QueryString["RecordNumber"].ToString()))
                ||
                (Request.QueryString["EmpEmail"] != null && !string.IsNullOrEmpty(Request.QueryString["EmpEmail"].ToString()))
                ||
                (Request.QueryString["Date"] != null && !string.IsNullOrEmpty(Request.QueryString["Date"].ToString()))
                ||
                (Request.QueryString["SlotID"] != null && !string.IsNullOrEmpty(Request.QueryString["SlotID"].ToString()))
                ||
                (Request.QueryString["Timeslot"] != null && !string.IsNullOrEmpty(Request.QueryString["Timeslot"].ToString()))
                )
            {

            }

我尝试使用它，并且效果很好.

i try with this and its working fine.

test.aspx?Fullname=test&RecordNumber=5&Date=12102010&SlotID=5&Timeslot=5&EmpEmail=test
