Requirement : when I select a item from dropdown and click add button. New tab and page view should be added. Load usercontrol
Inside the page view 

HTML --

<asp:dropdownlist id="ddlLanguages" runat="server">
</asp:dropdownlist>
<asp:linkbutton id="lbtAddLanguage" runat="server" text="Add" tooltip="Click to add this language"></asp:linkbutton>

<asp:panel id="pnlOuter" runat="server">
    <div id="divTab" runat="server">
     <asp:label id="lblTime" runat="server"></asp:label>
        <rad:radtabstrip id="TabStrip" runat="server" multipageid="MultiPage"
            autopostback="False">
            <tabs>
            </tabs>
        </rad:radtabstrip>
        <rad:radmultipage id="MultiPage" runat="server">
        </rad:radmultipage>
    </div>
</asp:panel>


Code -- 

protected override void OnInit(EventArgs e)
		{
			
			lbtAddLanguage.Click += new EventHandler(lbtAddLanguage_Click);
			MultiPage.PageViewCreated += new RadMultiPageEventHandler(radMultiPage_PageViewCreated);
			
			
		}

void lbtAddLanguage_Click(object sender, EventArgs e)
		{
			RadTab		tab = new RadTab();
			
			ListItem item = ddlLanguages.SelectedItem;
			tab.Text		= item.Text;
			RadPageView	view = new RadPageView();
			view.ID			= item.Value;
			tab.PageViewID = view.ID;
			tab.Selected = true;
			
			TabStrip.Tabs.Add(tab);
			MultiPage.PageViews.Add(view);
 
		}

void radMultiPage_PageViewCreated(object sender, RadMultiPageEventArgs e)
		{
			
			Details		detailControl		= LoadControl(Constant.CONTROL_WIZARD_DETAILS) as Details;
			if (detailControl != null)
			{
				detailControl.SelectedLanguage	= GetLanguage();
				detailControl.LoadControls();
				e.PageView.Controls.Add(detailControl);
			}
			
		}



My issue is, When I click the button to add tabs, PageViewCreated event fires before the button click and try to
Initialize all the page views. How can we stop this.
Thanks
