Hello,

 
You can wire the change event of the combobox and check the value of the selectedIndex:

function onChange(e) {
    var combobox = $(this).data("tComboBox");
    if (combobox.value() && combobox.selectedIndex == -1) {
        alert("custom value is entered");
    }
}

Hi Georgi Krustev,
 
     Thanks for this solution. We were tried this solution before we had posted this query here.
But the problem with this solution is, When we start to enter text in combo box, it will list down matched Items. If we select any one of the matched item by arrow down key and click on enter button. Even though its been selected from the list, selectedIndex become negative and prompt that Custom value is entered.

There is another case: When we start to enter text in combo box and if we have only one matched item. If you click either tab key or enter key now, matched item will be populated into Combo but still selectedIndex become negative only.

Could you please try in above stated way and give us solution..


Thanks.
