      RangeFilterState = new RangeFilterState()
  });
  state.Items.Add(new DashboardItemState("dateFilterDashboardItem1"){
      RangeFilterState = new RangeFilterState()
  });
  // ...
  e.InitialState = state
} 

VB.NET

Protected Sub ASPxDashboard1_SetInitialDashboardState(ByVal sender As Object, ByVal e As SetInitialDashboardStateEventArgs)
    Dim state = New DashboardState()
    ' ...
    state.Items.Add(New DashboardItemState("rangeFilterDashboardItem1") With {.RangeFilterState = New RangeFilterState()})
  state.Items.Add(New DashboardItemState("dateFilterDashboardItem1") With {.RangeFilterState = New RangeFilterState()})
