selectionChanged event is not fired when set selectedIndex
posted

Hi,

 

I am using igCombo in an ASP.NET MVC3 project, I found that the selectionChanged event is not fired when set selectedIndex. 

 

I used it like:

 

$("#comboCompanies").igCombo(
            {
                selectionChanged: function (evt, ui) {
                    var selectedId = ui.items[0].value;
                    DoSomething();
                }
            });

 

$("#comboCompanies").igCombo("selectedIndex", 2);

 



If the selection is made by the UI (I mean select option with mouse click), the selectionChanged will be fired.


But if I set the selection in code, the event won't be fired. Why?

    Hi, Jason,
    

    You have to bind events in ASP.NET in this way:
    

     
    

    $("#combo").igCombo({
    

                        dataSource: colors,
    

                        textKey: "Name",
    

                        valueKey: "Name",
    

                        width: "200px",
    

                        autoComplete: true
    

                  });
    

     
    

     
    

    $(document).delegate("#combo", "igcomboselectionchanged", function (evt, ui) {
    

                        var selectedId = ui.items[0];
    

                        console.log(selectedId.value);
    

    					});
    

     
    

     
    

    In order to trigger this event you have to set third parameter fire to true $("#combo").igCombo("selectedIndex", 2, true);
