Hi IG,
I am using MVC helper for cascading combos, and my child combo looks like this:

@(Html.Infragistics().Combo("subTaskDropdown", this.Model)

.ValueKey("Id")

.TextKey("Name")

.DataSourceUrl("subtask-combo-data")

.DataBind()

.FilteringType(ComboFilteringType.Local)

.RenderMatchItemsCondition(ComboRenderMatchItemsCondition.Contains)

.FilteringCondition("contains")

.CaseSensitive(false)

.AutoComplete(false)

.DropDownWidth(250)

.Width("250")

.CascadingSettings(settings => settings.ParentComboID("#taskDropdown").ParentComboKey("TaskId"))

.AddClientEvent("filtered", "subtaskFiltered")

.AddClientEvent("selectionChanged", "subtaskSelectionChanged")

.NullText("Select SubTask:")

.ItemTemplate("<span class='ComboText'>${Name}</span>")

.Render()

)

After selecting a value in this combo I open partial view with detail, where I update datasource for the combo on button click using ajax, something like this:

function SaveEXTask() {

$.ajax({

url:'/ETL/SaveSubtask',

data: $('#Form1').serializeArray(),

type:'POST',

success:function(data)....

My question is - what would be the correct way to refresh/rebind combo after underlying source has been updated in my case?

Thanks
