I have a drop down list whose datasource is updated from another control. The dropdown list is part of a trio of cascading dropdowns.
I call RefreshDataAsync to update the dropdowns datasource having changed it from the other control. I can make the dropdown reflect the datasource change by refreshing the entire page using uriHelper.NavigateTo(uriHelper.Uri, forceLoad: true); but that obviously looses state of all controls on the page which is not desirable.
Is there a better way to do this so state is not lost on the other controls on the page (like calling StaeHasChanged from the dropdown whose datasource has changed?
Many thanks in advance
