disable items of a foreign key column

[Vlad]

Do you know if it's possible to make some items of a dropdown list ( foreign key column) disabled and the rest enabled - based on a datasource property ?

Hello Vlad,

I am afraid it is not possible to achieve such exact behavior.

You to bind to the select event of the ForeignKey dropdownlist and prevent the selection if the select item does not meet some requirement.

Here is an example:

$('#gridname').getKendoGrid().bind('edit',function(e){
         e.container.find('[data-role=dropdownlist]').data().kendoDropDownList.bind('select',function(a){
               if(a.item.text()=="some text of an item"){
                      e.preventDefault();
               }
        })
})

However this will not keep the DropDownList opened and it will also not make that particular item to look unselectable.
