does not contain a definition for 'Y' and no extension method 'Y' accepting a first argument of type 'X' could be found

My newTransport.aspx button control

<asp:Button ID="najitRidiceButton" runat="server" Text="Vyhledat ridice" onclick="najitRidiceButton_Click" />

My newTransport.aspx.cs method

protected void najitRidiceButton_Click(object sender, EventArgs e)
{
    DAODriver.searchDrivers(Calendar1.SelectedDate, casPrepravyTextBox.Text, Int32.Parse(pocetOsobTextBox.Text), extraZavazadla());
}

Error i get

CS1061: ASP.newtransport_aspx does not contain a definition for najitRidiceButton_Click and no extension method najitRidiceButton_Click accepting a first argument of type ASP.newtransport_aspx could be found (are you missing a using directive or an assembly reference?)

when i delete that button, everything works correctly, so i don´t understand it, this is my first ASP.NET web app so please help me i have no idea why it doesn´t work, although i tried to google it or find answer here on stackoverflow - no result

<%@ Page Title="" Language="C#" MasterPageFile="~/PageTemplate.Master" 
AutoEventWireup="true" CodeBehind="NewTransport.aspx.cs" 
Inherits="ASPDU1.NewTransport" %>

you seem to be using the ASP.NET WebApplication (i.e., not the ASP.NET WebSite) project type. If so, it is necessary to:

  • Build the application and make sure that the build is successful;
  • Re-deploy the required page/code/designer (or better a complete project) with the just built APPLICATION_NAME.DLL file onto the destination hosting server directory.

I have had great success with changing build configuration (e.g. from debug to release), run the project, and then change back to the previous build configuration.

Try by making the event handler public void instead of protected, just to see. It works for me as protected void, but there maybe something here that I can't figure out from this sample. I assume that the code-behind is pointed to the correct page in the ASPX markup's @Page reference.
