PostBack / AutoPostBack / NavigateURL problems

[Chris]

I am using Q1 2009 release of the ASP.NET Ajax toolset. I have created a toolbar and when I attempt to set a Navigate URL with a specified target, the Navigate works great but it opens in both the parent window and the new window. Am I doing something wrong here!?

            <telerik:RadToolBar ID="tbTicketDetails" runat="server" Width="100%" AutoPostBack="true">
                <Items>
                    <telerik:RadToolBarButton runat="server" Text="Add Notes" ImageUrl="~/Images/notebook_pencil.png"
                        Value="AddNotes" CommandName="AddNotes" OnLoad="GetItemURL">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Close" ImageUrl="~/Images/door.png"
                        Value="CloseTicket" CommandName="CloseTicket" OnLoad="GetItemURL">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Lock" ImageUrl="~/Images/lock.png"
                        Value="LockTicket" CommandName="LockTicket">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Unlock" ImageUrl="~/Images/lock_unlock.png"
                        Value="UnlockTicket" CommandName="UnlockTicket">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Claim Ticket" CommandName="ClaimTicket"
                        ImageUrl="~/Images/card_claimticket.png" Value="ClaimTicket">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Release Ticket" CommandName="ReleaseTicket"
                        ImageUrl="~/Images/card_releaseticket.png" Value="ReleaseTicket">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Assign Ticket" CommandName="AssignTicket"
                        ImageUrl="~/Images/card__assignticket.png" Value="AssignTicket" OnLoad="GetItemURL">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Move Ticket" CommandName="MoveTicket"
                        ImageUrl="~/Images/pin_moveticket.png" Value="MoveTicket" OnLoad="GetItemURL">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Reopen Ticket" CommandName="ReopenTicket"
                        Value="ReopenTicket" ImageUrl="~/Images/reopenticket.png" OnLoad="GetItemURL" />
                    <telerik:RadToolBarButton runat="server" Text="Delete Ticket" CommandName="DeleteTicket"
                        ImageUrl="~/Images/delete.png" Value="DeleteTicket">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Restore Ticket" CommandName="RestoreTicket"
                        ImageUrl="~/Images/restore.png" Value="RestoreTicket">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Edit Ticket Details" CommandName="EditDetails"
                        ImageUrl="~/Images/ticket_pencil.png" Value="EditDetails" Visible="false" OnLoad="GetItemURL">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Assign Goal" CommandName="AssignGoal"
                        ImageUrl="~/Images/accreditationgoal.png" Value="AssignGoal" OnLoad="GetItemURL">
                    </telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" IsSeparator="true"></telerik:RadToolBarButton>
                    <telerik:RadToolBarButton runat="server" Text="Print" CommandName="PrintWorkOrder"
                        ImageUrl="~/Images/print.png" Value="Print" OnLoad="GetItemURL" Target="_blank" PostBack="false"></telerik:RadToolBarButton>
                </Items>
            </telerik:RadToolBar>

And here is the OnLoad event handler that sets the Navigate URL -- the button with the problem is the last button "Print".

    Protected Sub GetItemURL(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim item As Telerik.Web.UI.RadToolBarButton
        If sender.GetType Is GetType(Telerik.Web.UI.RadToolBarButton) Then
            item = DirectCast(sender, Telerik.Web.UI.RadToolBarButton)
            Select Case item.Value
                Case "AddNotes"
                    item.NavigateUrl = "NoteEditor.aspx?TID=" & TicketID & "&MD=E"
                Case "CloseTicket"
                    item.NavigateUrl = "CloseWorkOrder.aspx?TID=" & TicketID
                Case "AssignTicket"
                    item.NavigateUrl = "NoteEditor.aspx?TID=" & TicketID & "&MD=A"
                Case "MoveTicket"
                    item.NavigateUrl = "NoteEditor.aspx?TID=" & TicketID & "&MD=M"
                Case "EditDetails"
                    item.NavigateUrl = "EditTicketDetails.aspx?TID=" & TicketID
                Case "AssignGoal"
                    item.NavigateUrl = "UpdateAccreditationGoal.aspx?TID=" & TicketID
                Case "ReopenTicket"
                    item.NavigateUrl = "ReopenTicket.aspx?TID=" & TicketID
                Case "Print"
                    item.NavigateUrl = "PrintTicketView.aspx?TID=" & TicketID
                    item.Target = "_blank"
            End Select
            item.PostBack = False
        End If
    End Sub

When I click on the print button, the URL is opened in a new window plus the parent window. Am I doing something wrong here?

Hi Chris,

This issue is already fixed in Q2 release of RadControls, could you please download it and give it a try?

I would love to upgrade, but our organization is locked into 2009 Q1 at the moment as all of our internal projects using these tools are not to be beyond this version. We will be considering an upgrade after January 2010, so are there any work arounds that are available?

Hi Chris,

Please subscribe to OnClientButtonClicking event of the toolbar and in its handler:

<script type="text/javascript">
    function buttonClicking(sender, args) {
        if (args.get_item().get_linkElement().target == "_blank") {
            args.set_cancel(true);
            window.open(args.get_item().get_navigateUrl());
        }
    }
</script>
