Accessing multiple controls inside listview

[Josh]

I have set of controls inside of a list view in which I want to be disabled until a certain checkbox is checked.
My current code looks like this:

protected void chckRSMCA_CheckedChanged(object sender, EventArgs e)
{
            CheckBox checkboxRS = (CheckBox)sender;
            RadTextBox Id = (RadTextBox)rlvListView.FindControl("txtRSFarmIdMCA");
            RadTextBox Address = (RadTextBox)rlvListView.FindControl("txtRSSvrAddressMCA");

            if (checkboxRS.Checked)
            {
                Id.Enabled = true;
                Address.Enabled = true;
            }
            else
            {
                Id.Enabled = false;
                Address.Enabled = false;
            }
}

However, with this code I get null reference exception when it tries to set the Enabled setting.

Figured it out.
This code works however, there was a simple typo.
