Are you trying to find the textbox that resides inside the repeater? If so, you could use the method below which searches based on the ID of the control - you could modify it to check based on the clientID of the control instead.

  public static System.Web.UI.Control FindControlIterative(System.Web.UI.Control root, string id)
    {
        System.Web.UI.Control ctl = root;
        var ctls = new LinkedList<System.Web.UI.Control>();

        while (ctl != null)
        {
            if (ctl.ID == id)
                return ctl;
            foreach (System.Web.UI.Control child in ctl.Controls)
            {
                if (child.ID == id)
                    return child;
                if (child.HasControls())
                    ctls.AddLast(child);
            }
            if (ctls.First != null)
            {
                ctl = ctls.First.Value;
                ctls.Remove(ctl);
            }
            else return null;
        }
        return null;
    }

Do you have access to the specific RepeaterItem (like you would in the ItemDataBound event handler)?

If so, you can do repeaterItem.FindControl("YourControlId") to get the child control.
