Hi. Is't possible to disable Combobox DropDownList, when disabling Combobox in js? Because in my project when disabled Combox, i can click on combobox and to choose value from list.

 Dmitrij,  if you are using 8.2.* versions of DXperience you can use the SetEnabled() function of the clientside library.  ASPxClientComboBox.SetEnabled(false);

 No. i'm using version 8.1. That mean, that in this version exist bug with combobox?

 no, that functionality only exists in 8.2 and above.  I suggest upgrading to 8.2

 if you cant upgrade, i suggest looking at this http://www.devexpress.com/Support/Center/p/Q91215.aspx
