How to disable default dropdown opening?

Answer 1

I'm not sure whether you're trying to disable the dropdown . If so try using the below code to disable it.

 
 
 
  
  $("#" + ControlId + "_text").attr("disabled", true);
 
  

Also check your HTML code, it has to be cleaned up.

EDIT1: If you're using jQuery 1.6+, then try using prop;

 
 
 
  
  $("#" + ControlId + "_text").prop("disabled", true);
 
  

EDIT2: Hide to option when dropdown is clicked.

 
 
 
  
  $("#" + ControlId).click(function () { $("#" + ControlId + " options").hide(); });
 
  

EDIT3: You're trying to have a placeholder for SELECT tag , currently it is unavailable. Remove your inline styles for select and add the following css to your code.

 select { max-width:150px; background:White; height: 25px; } /* Hidden placeholder */ select option[disabled]:first-child { display: none; }
