Remove it, then Right Click on that file -> Convert to Web Application.
It will create the updated designer file for you. Try and let me know.

Otherwise add the following code in Designer file manually.

/// <summary>
/// Label2 control.
/// </summary>
/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
/// </remarks>
protected global::System.Web.UI.WebControls.Label Label2;

Hi Tradit I tried it but still nothing (in the designer.cs it already have it)
I delete it and I create it again but still nothing.

Can you show the .cs code where you exactly trying to access the Label?

JasonTsoum77 2-Nov-13 9:06am

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace FurSiteMs.PDT
{
public partial class PDTSuccess
{

///

/// form1 control.
///

/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
///
protected global::System.Web.UI.HtmlControls.HtmlForm form1;

///

/// Label1 control.
///

/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
///
protected global::System.Web.UI.WebControls.Label Label1;

///

/// Label2 control.
///

/// <remarks>
/// Auto-generated field.
/// To modify move field declaration from designer file to code-behind file.
///
protected global::System.Web.UI.WebControls.Label Label2;
}
}

No, not this. I want to see the code aspx.cs file where you have written Label2.Text.

This is aspx page. I want to see the code page that is aspx.cs where you have written Label2.Text.

JasonTsoum77 3-Nov-13 13:43pm

Oh i'm sorry here it is
StreamReader stIn = new StreamReader(req.GetResponse().GetResponseStream());
strResponse = stIn.ReadToEnd();
stIn.Close();

// sanity check
Label2.Text = strResponse;

// If response was SUCCESS, parse response string and output details
if (strResponse.StartsWith("SUCCESS"))
{
PDTHolder pdt = PDTHolder.Parse(strResponse);
Label1.Text = string.Format("Thank you {0} {1} [{2}] for your payment of {3} {4}!",
pdt.PayerFirstName, pdt.PayerLastName, pdt.PayerEmail, pdt.GrossTotal, pdt.Currency);
}
else
{
Label1.Text = "please retry";
}

It should work. Please clean your project and then rebuild it. Do it multilevel times.

If this doesn't work, then create another Lable with different Id and use that. Remove Label2.

JasonTsoum77 3-Nov-13 14:00pm

Ok I will try it and I will inform you
thnx for your help and your time Tadit

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 3-Nov-13 14:06pm

Most welcome buddy. Okay, but don't forget to inform me. I am waiting.

JasonTsoum77 5-Nov-13 4:56am

Hey! Tadit still nothing with my issue i clean my project i rebuid it but "label.text" still not recognised, in another project where i have similar issue it worked with clean and rebuild it. The final solution which i will try is to recreate the whole project

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 5-Nov-13 7:05am

Did you try deleting this label and create another Label with a different ID?

JasonTsoum77 6-Nov-13 10:58am

Hi Tadit sorry for my late response I try it, I delete the current labels from aspx,cs and designer.cs and I create news like:
protected global::System.Web.UI.WebControls.Label L1;
but still nothing vs returns "L1 does not exist to the current context".
today I will try to delete the whole form and recreate it step by step to see where is the wrong.

Iam not very experince developer with vs and asp.net/c# but i see that vs has a little problem on handling namespaces...

I will late you know what will be happened.

Thnx for your help

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 6-Nov-13 12:18pm

Try adding Labels from the ToolBox. Don't create them manually.
See what happens.

JasonTsoum77 8-Nov-13 6:38am

Hi Tadit, yes from the toolbox I add the labels but they didn't work I added protected global::System.Web.UI.WebControls.Label L1; because in .cs
I use "namespace FurSiteMs.PDT".

But Finally it worked I delete the whole form and I import every item step by step and once a time.
It is very stupid because the is exactly the same with the previous one (i compare it with beyond compare to see if there are any differences).
Anyway the problem solved with this anorthodox way.

Thnx for your time and your help!

Such things happen when you try not to work the way ASP.NET works. Create new page,drag label on it. Press F7 on that page and try to assign text for that label. See the difference between this and the page you are about to create. You will get an answer.

ZurdoDev 1-Nov-13 9:09am

Just rename it and see if it creates the designer part properly. Or do as Tadit says.

JasonTsoum77 1-Nov-13 9:13am

Hi I don'y know if i'm doing something wrong but i can't find the option with right click on aspx file convert to web application . I'm using Visual studio 2012 so i thing there is the problem.
Any idea how can i do this in vs2012

This happens to me sometimes when I add controls to the HTML while I'm debugging. I usually stop the debugger, backspace over the HTML of the control I've added, and when I re-type the ">" to close the element, the designer kicks in, gives the tag the correct closing tag, and adds the control correctly to the designer file so it can be accessed in my class.

Hi,

The only thing I can think of besides redoing your sheets is maybe you are not typing the Label2 in the correct place in the CS file. I would try creating a method and placing the Label2 in there. Hope this helps!

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
Label2.Text = "hello world";
}

Solution 2

After a lot of Hit and Trial, finally OP (JasonTsoum77) created a new Web Form from the Scratch and added the Labels again.

Surprisingly, it worked and issue is solved. :)
