    I use entity datasource for the tabstrip, but in the TabSelected event, the dataItem for the selected tab is 'nothing'. (I use templates for tabs)

    How to get the dataitem in the 'tabselected' event


        Protected Sub TabSelected(ByVal sender As Object, ByVal e As RadTabStripEventArgs)
            Me.uxTabStrip.SelectedIndex = e.Tab.Index
            Dim entity= TryCast(e.Tab.DataItem, entity)
        End Sub

    ##  entity is 'Nothing' here

    Hi Naresh,

    The reason for the experienced behavior is due to the fact that the DataItem is only available when biding the RadTabStrip.It is not persisted across post-backs in order to optimize the performance. This means that you could access it in TabDataBound event for instance. If you want to persist some values from the DataItem you should bind them as custom attributes to your Tabs.
