Disabling the DateTime Picker Textbox

Disabling the DateTime Picker Textbox

Hi Team ,

I just wanted to Disable and enable the Datetime picker TextBox  in Jquery?
i have a  Simple TextBox  , and Another Textbox Which is a DateTime Picker.
if i enter the Value in First TextBox , then only My Second Datetime Picker Textbox Should get Enabled.
 i  have done , but facing the Issue of Image icon of DateTimePicker also , the Textbox gets disabled but Still on click of image icon , Calender Displays.  In the Disabled mode i dont want the image icon to display calender.
Please find below Code Snipplet
in the HTML View
<input type = Textbox value ="Place"  id="Textbox1" name="Textbox1"/ > 
<input type = Textbox value ="Place"  id="TextboxForDate" name="TextboxForDate"/ > 

in Javascipt
 $(function () {
            $("#TextboxForDate").datepicker({
                minDate: 0,
                showOn: "button",
                buttonImage: "../../Content/themes/base/images/calender-icon.png",
                buttonImageOnly: true,
                buttonText: "Select date",
});


 I want in Disabled Mode , the Image Icon Should not Display Calender
