simple onclick event handler question

I have a very simple question about event handlers.

I've created a very simple form page with a textbox and image button.

when the image button is clicked I want to pass the value in the text box in a querystring, redirecting to another URL:

Here is my event handler:

protected void SearchImageButton_Click(object sender, ImageClickEventArgs e)
{
Response.Redirect("http://search.mysite.com:9000/cgi-bin/query?mss=search&op=x&i=mysite&9=" + the textbox value
}

The name of my textbox is SearchTextBox

How do I pass that value in my the querystring?

I tried to run the page and got the following error message:

ASP.mainmaster.master does not contain a definition for 'SearchImageButton_Click'

Here is the relevant section with the web controls on my masterpage:

<td>
<form runat="server">
Search <asp:TextBox ID="SearchTextBox" runat="server" Height="15px" Width="150px"></asp:TextBox>
<asp:ImageButton ID="SearchImageButton" runat="server" ImageAlign="Middle" ImageUrl="~/images/go.gif" OnClick="SearchImageButton_Click" />
</form>
</td>

And this is the master page code behind:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Template : System.Web.UI.MasterPage
{

protected void Page_Load(object sender, EventArgs e)
{

}
protected void SearchImageButton_Click(object sender, ImageClickEventArgs e)
{
Response.Redirect("http://search.compasslearning.com:9000/cgi-bin/query?mss=search&op=x&i=CompassLearning&9=" + this.SearchTextBox.Text);
}
}
