Dear Telerik Team,

I'm new to the RadTabStrip and I'm trying to use it by the on demand approach.

I did follow some of the example in your web site and I'm using UserControl to display deferent content.

How I can load and show the first UserControl for the first time the page appears. Because my current situation is I have to click one tab first in order to load the related UserControl.

Thanks.

Code Behind File:
    Dim IsNewPageView As Boolean = False
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Me.Page.IsPostBack Then
            ViewState("sequence") = 0
        End If
    End Sub

    Protected Sub RadTabStrip1_TabClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTabStripEventArgs) Handles RadTabStrip1.TabClick
        e.Tab.PageViewID = AddPageView(e.Tab.Text)
        e.Tab.PageView.Selected = True
    End Sub

    Private Function AddPageView(ByVal PageViewID As String) As String
        Dim PageView As RadPageView = New RadPageView
        PageView.ID = PageViewID
        IsNewPageView = True
        Me.RadMultiPage1.PageViews.Add(PageView)
        Me.RadMultiPage1.SelectedIndex = Me.RadMultiPage1.PageViews.Count - 1
        Return PageViewID
    End Function

    Protected Sub RadMultiPage1_PageViewCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMultiPageEventArgs) Handles RadMultiPage1.PageViewCreated
        Dim Sequence As Integer = 0
        If IsNewPageView Then
            Sequence = Convert.ToInt32(ViewState("sequence")) + 1
            ViewState("sequence") = Convert.ToString(Sequence)
        Else
            Sequence = e.PageView.MultiPage.PageViews.Count
        End If

        Select Case e.PageView.ID.Trim.ToUpper
            Case "Permanent".ToUpper
                Dim userControlName As String = "Permnent.ascx"
                Dim userControl As Control = Page.LoadControl(userControlName)
                userControl.ID = e.PageView.ID & "_Permnent"
                e.PageView.Controls.Add(userControl)
            Case "Standby".ToUpper
                Dim userControlName As String = "Standby.ascx"
                Dim userControl As Control = Page.LoadControl(userControlName)
                userControl.ID = e.PageView.ID & "_Standby"
                e.PageView.Controls.Add(userControl)
        End Select
    End Sub

ASPX File (Java Script:)
<script type="text/javascript">
    function onTabSelecting(sender, args)
    {
        if (args.get_tab().get_pageView())
        {
            if (args.get_tab().get_pageView().get_id())
            {
                args.get_tab().set_postBack(false);
            }
        }
    }
