Error cs1061 как исправить

I am new to .NET visual studio, building windows Form Application.

I had the following error described below, when trying to build a solution. I am not sure if it has to do with something related to the file ‘SuperAdventure.SuperAdventure’ or a control that was not specified.

‘SuperAdventure.SuperAdventure’ does not contain a definition for ‘label5_Click‘ and no extension method ‘label5_Click’ accepting a first argument of type ‘SuperAdventure.SuperAdventure’ could be found (are you missing a using directive or an assembly reference?)

This is the error code with the error showing a red squiggly/line under the code in the marked line.

// lblExperience
// 
this.lblExperience.AutoSize = true;
this.lblExperience.Location = new System.Drawing.Point(110, 73);
this.lblExperience.Name = "lblExperience";
this.lblExperience.Size = new System.Drawing.Size(35, 13);
this.lblExperience.TabIndex = 6;
this.lblExperience.Text = "label7";
this.lblExperience.Click += new System.EventHandler(this.label5_Click); // <-- squiggly line here

and on the output it gives this:

1. 1>—— Build started: Project: Engine, Configuration: Release Any
   CPU ——

2. 1> Engine -> C:UsersAdminDocumentsVisual Studio
   2013ProjectsSuperAdventureEnginebinReleaseEngine.dll

Please let me know if I need to provided any more information.
PS: I am a beginner trying to learn some C# by building a RPG game as an exercise.

I’m having a bit of a pain here and I just can’t figure out what’s wrong.

I have an ASP.net project which I deployed on a server. At first everything seemed allright, no Errors whatsoever. However, as a last adition I wanted to add a search function to a fairly large list so I added the following syntax to my mark-up:

<td>
    Search Server:
    <asp:TextBox ID="txtSearch" runat="server" />
    <asp:Button ID="btnLookup" runat="server" OnClick="btnLookup_Clicked" Text="Search" />
    <asp:Label ID="lblFeedback" runat="server" />
</td>

and the following in code behind:

protected void btnLookup_Clicked(object sender, EventArgs e)
{
    lblFeedback.Text = "";
    Session["IsSearch"] = true;
    LoadServerList();
}

When I run this locally it works just fine as I expect.
HOWEVER!

When I copy these files to the server I get a compilation error:

Compiler Error Message: CS1061: ‘ ASP.ntservice_ reports_ reports_ serverlist_ manage_ aspx ‘ does not contain a definition for ‘btnLookup_ Clicked’ and no extension method ‘btnLookup_ Clicked’ accepting a first argument of type ‘ASP.ntservice_ reports_ reports_ serverlist_ manage_ aspx’ could be found (are you missing a using directive or an assembly reference?)

it says there is nothing that handles my Clicked event although it does work when I run it through Visual studio.

any ideas?

EDIT:
What I tried myself is

• renaming button
• deleting and readding the button
• add through designer
• renaming click event
• removing the event from markup allows normal execution … :/
