Hello Tammy,

Thank you for posting in our community.

Events for the igCombo editor could be hooked in the editorOptions. All events that are applicable for the igCombo (which could be found here) could be attached for the editor provider as well.  For example the SelectionChanged event could be achieved as following:

[code]

  $("#gridManageView").igGrid({

.

.

  features: [

{
       name: "Updating",
       enableAddRow: true,
       enableDeleteRow: true,
       columnSettings: [
          {
                columnKey: "viewType", editorType: "combo", required: true,
                 editorOptions: {
                    mode: "dropdown",
                    textKey: "Text",
                    valueKey: "Value",
                    dataSource: viewOptions,
                    dataSourceType: "json",
                    width: "100%",
                    autoComplete: false,
                    filteringType: "local",
                    renderMatchItems: "contains",
                    enableClearButton: true,
                    mode: "editable",
                    selectionChanged: function (e, args) {
                       //handle your event here
                        alert("Event Fired!");
                    }
            }
     },
                                           
  ]

}

]

});

[/code]

I am also attaching a small sample illustrating my suggestion for your reference.

Please have a look at the provided sample and let mw know if you have any additional questions afterwards.

When using the MVC wrappers event handlers could be attached after the controls initialization using jQiery delegate. Handlers are attached to one or more events for all elements that match the selector. Basically, this means that the ID option of the combo editor should be set in order to get reference to this particular element and hook the event. For example:

@(Html.Infragistics().Grid(Model)
  .ID("grid1")
  .Width("100%")
  .AutoGenerateColumns(false)
  .AutoCommit(true)
  .PrimaryKey("ProductID")
  .Columns(col =>
{
    col.For(c => c.ProductID).HeaderText("ProductID").Width("0%");
    col.For(c => c.Name).HeaderText("Name").Width("20%");
    col.For(c => c.ReleaseDate).HeaderText("ReleaseDate").Width("50%");
    col.For(c => c.Status).HeaderText("Status").Width("20%").FormatterFunction("formatStatus");
})
.Features(features =>
{ 
   features.Updating().EditMode(GridEditMode.Row).ColumnSettings(cs => {
       cs.ColumnSetting().ColumnKey("Status").EditorType(ColumnEditorType.Combo).ComboEditorOptions(co => co.DataSource(ViewBag.Statuses).ID("comboEditor").ValueKey("Key").TextKey("Value").Mode(ComboMode.DropDown));    
   });
})
.UpdateUrl(Url.Action("UpdateURLAction"))
.DataSourceUrl(Url.Action("GetData"))
.Render())

// 
        $(document).delegate("#comboEditor", "igcomboselectionchanged", function (evt, ui) {
           alert("Selection Changed event is fired");
        });

// ]]>

I am also attaching a application project illustrating my suggestion for your reference. Please have a look at the provided sample and do not hesitate to contact me if you have any additional questions afterwards.

Thank you for using Infragistics components.
