Manually Initialize ComboBox list via javascript

[nick]

For the life of me, I've been trying to search of a way to manually initialize a radcombobox. I'm able to initialize it via the ItemsRequested event like so

Public Sub IndustryAssigment_ItemsRequested(sender As Object, e As RadComboBoxItemsRequestedEventArgs)

Dim IlkIndustryTaxonomyTier3Source = New List(Of lkIndustryTaxonomyTier3)
IlkIndustryTaxonomyTier3Source = _IlkIndustryTaxonomyTier3Manager.List()
_view.GetrcbMacroOTHemscott3.DataTextField = "OTHemscott3"
_view.GetrcbMacroOTHemscott3.DataValueField = "OTHemscott3PK"

_view.GetrcbMacroOTHemscott3.DataSource = IlkIndustryTaxonomyTier3Source
_view.GetrcbMacroOTHemscott3.DataBind()
End Sub

But this is only called upon firing the said event. 

Is there a way to manually fire this event via javascript as this combobox is inside a radwindow that is being opened via another javascript call.

Hi Nick,

If I understand correctly your requirement, you need to set the data to the RadComboBox, without opening the popup. If that is the case, this defeats the purpose of the LoadOnDemand functionality, so you could use another approach for binding the data:

• http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/data-binding/binding-to-array-or-arraylist
• http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/data-binding/overview

Hope this helps.
