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.NET

<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" />

Below is how i recieve my passed values

C#

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());


                }

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

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" />

and
on code write this

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

try changing if condition like below

VB

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()))
                )
            {

            }

i try with this and its working fine.

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