I cannot access any of my asp controls in my codebehind. The .aspx page is as follows

The codebehind is
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class ChangePassword : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//TextBox password = (TextBox)ChangePassword1.FindControl("CurrentPassword");
//Label passwordLabel = (Label)ChangePassword1.FindControl("CurrentPasswordLabel");
TextBox password = ChangePassword1.FindControl("CurrentPassword") as TextBox;
Label passwordLabel = ChangePassword1.FindControl("CurrentPasswordLabel") as Label;
//TextBox CurrentPassword = ChangePassword1.FindControl("CurrentPassword") as TextBox;
if (Request.QueryString["p"] != null)
{
passwordLabel.Visible = false;
password.TextMode = TextBoxMode.SingleLine;
password.Visible = false;
password.Text = Request.QueryString["p"];
}
}
protected void ChangePassword1_ChangedPassword(object sender, EventArgs e)
{
}
protected void HomePageButton_Click(object sender, EventArgs e)
{
//Link.ToHomePage();
Response.Redirect("HomePage.aspx");
}
}
The problem I am having is I get a object reference not set to an instance of an object on passwordLabel and password. Does anyone know how to get these into scope so that I can edit there text and visibility properties in the codebehind?
Try using:
