I am using a Teleric RadTabStrip. In RadPageView I have three Usercontrols.

<telerik:RadTabStrip  runat="server" ID="RadTabStrpWrkSpace" AutoPostBack="True" RenderSelectedPageOnly="true"
                    SelectedIndex="0" ReorderTabsOnSelect="True" Align="Justify" MultiPageID="RadMultiPageState"
                     önTabClick="RadTabStrpWrkSpace_click" Height="37px" Width="946px">
                    <Tabs>
                        <telerik:RadTab Text="Federal Adjustments" PageViewID="FederalAdjusPage" Selected="True">
                        </telerik:RadTab>
                        <telerik:RadTab Text="Payments" PageViewID="PaymentsPage">
                        </telerik:RadTab>
                        <telerik:RadTab Text="State Sourcing" PageViewID="StateSourcingPage">
                        </telerik:RadTab>
                    </Tabs>
                </telerik:RadTabStrip>
                <telerik:RadMultiPage  runat="server" ID="RadMultiPageState" SelectedIndex="0" RenderSelectedPageOnly="true">
                    <telerik:RadPageView  runat="server" ID="FederalAdjustments" Height="700px" Selected="true">
                        <uc:fa id="FA1"  runat="server" />
                    </telerik:RadPageView>
                    <telerik:RadPageView  runat="server" ID="Payments" Height="700px"  önPageViewCreated="RadMultiPage1_PageViewCreated">
                        <uc:pa id="PA1"  runat="server" />
                    </telerik:RadPageView>
                    <telerik:RadPageView  runat="server" ID="StateSourcing" Height="700px"  önPageViewCreated="RadMultiPage1_PageViewCreated">
                        <uc:ss id="SS1"  runat="server" />
                    </telerik:RadPageView>
                </telerik:RadMultiPage>

Now when the page loads, it is firing the page_load event of all the three user controls. Is there any way, that I can fire the page_load event of the required usercontrol only either in page_load or tab changing.
