<telerik:RadToolBar ID="RadToolBar1" Runat="server" Height="100%" Skin="Forest" Width="100%">
    <Items>
        <telerik:RadToolBarButton Width="100%" runat="server" Text="Button1">
            <ItemTemplate>
                <asp:ImageButton ID="btnoweb"      runat="server" Height="50"
                    ImageUrl="~/images/o!logo.png" Width="50" />
                <asp:ImageButton ID="btnCalender"     runat="server"
                    ImageUrl="~/images/Picture5.png" OnClick="btnCalender_Click" />
                <asp:ImageButton ID="btnAttach"    runat="server" ImageUrl="~/images/Attach.png" />
                <asp:Menu ID="mnuMenu" runat="server">
                </asp:Menu>
                <telerik:RadMenu ID="mnuAdd"   runat="server" Visible="true">
                    <ItemTemplate>
                        <asp:Image ID="imgicon"     runat="server" EnableViewState="false"
                            ImageUrl="~/images/Add.png" />
                    </ItemTemplate>
                </telerik:RadMenu>
                  <asp:TextBox runat="server" ID="txtsearch" OnTextChanged="Bind_SearchBox" Font-Size="X-Large" Height="40px" Width="650px" onkeyup="this.onchange();" AutoPostBack="true" />
                <asp:ImageButton ID="btnsearch"     runat="server"
                    ImageUrl="~/images/btnsearch.png" OnClick="btnSearch_Click" />
                <asp:ImageButton ID="btnCancel"    runat="server" ImageUrl="~/images/Cancel.png"
                    OnClick="btnCancel_Click" />
            </ItemTemplate>
        </telerik:RadToolBarButton>
    </Items>
</telerik:RadToolBar>

and when i click any button on the ToolBar i get the Following Error

Server Error in '/o!Pilot' Application.

Source Error:


and my Scheduler is defined like this

         

  <telerik:RadScheduler ID="RadScheduler1"  runat="server" Skin="Forest"
    Width="100%" Height="100%" style="margin-left: 0"
    EnableViewState="false" Visible="false">
</telerik:RadScheduler>

and that EnableViewState="false" property is i set it to true, i get the Error even before the page load.

Thanks
