In order to open the filtering control when the user clicks the column header, you can subscribe to the Sorting
event of the control. Within the event handler, you can adopt the approach demonstrated in this help article
. You need to also cancel the event, so that the column is not being sorted through the built-in mechanism.
As to your requirement to sort the items when the user clicks the filtering funnel, the event you need to handle is FilterOperatorsLoading
. When it is raised, you can set the IsOpened
property of the PopUp
to false and programmatically sort the items of RadGridView
, as demonstrated in this help topic
Hope this helps.
