I'm sure this is really simple and I'm missing something obvious but....

I have a tab strip which moved between pageviews when you click on a tab. Ideally when a user clicks on a tab I want to do some server side processing to populate the pages controls with values.

I naturally assumed in the Page_Load sub I could use this code:

Code: Visual Basic.NET 
If Me.TabStrip1.SelectedIndex = 2 Then
            Populate_Controls(...)
        End If

However, the value for SelectedIndex is always -1 regardless to the tab selected, thus making it so I can't work out which tab was clicked. Could you give me some pointeres on how to run server side code as to when a tab is clicked? A different function/sub per tab would be fine.

Thanks
Ed

Hi Ed,

You can handle TabStrip_ItemClick event. Inside that event you can use:

if e.TabItem.Index == 2 Then
.....

That should give you the correct value. Note you may need to use CType(e.NavigationItem, EO.Web.TabItem).Index because property e.TabItem has only been added very recently.

Thanks

Sorry I'm being a bit thick, could you give me the full sub declaration?

Here you go:

Code: Visual Basic.NET 
Private Sub TabStrip1_ItemClick(
    sender As Object, e As EO.Web.NavigationItemEventArgs) 
    Handles TabStrip1.ItemClick
    If e.TabItem.Index = 2 Then
         ...do something.....
    End If
End Sub 'TabStrip1_ItemClick


Thanks
