The name 'txtinput1' does not exist in the current context

[tralpatly]

First off , I know the question looks very similar to the question hereBut somehow the fixes suggested there arent working for me. So here goes.I have the following code in my aspx page :\[code\] <asp:TextBox ID="txtinput1" runat="server" Width="200px" ontextchanged="txtinput1_TextChanged"></asp:TextBox>\[/code\]But when I try the following code in my code behind:\[code\] protected void Page_Load(object sender, EventArgs e) { StemService.ServiceClient myClient = new StemService.ServiceClient(); string input = txtinput1.Text; }\[/code\]I get the error saying that 'txtinput1' does not exist in the context.For sake of completion here's my default.aspx https://gist.github.com/KodeSeeker/5217410.P.S. Im a C# noob, so I may be missing something obvious.EDIT: Designer.cs https://gist.github.com/KodeSeeker/5217484EDIT 2: Default.aspx.cs: https://gist.github.com/KodeSeeker/5217517
