RibbonBar multiple postback

[Gordon]

We upgraded to the newest release version of the RadControls today.  When we did that, we noticed that our pages started to hit the Page_Load function multiple times for each request.  We created a small Telerik Web Application and found that the RibbonBarGroup in the RibbonBar control is causing the issue.

We used Visual Studio 2010 and created a Telerik Web Application project in VB.  We have a master page, an aspx page and a vb code behind for each.

RibbonBar.Master

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
</telerik:RadScriptManager>
<telerik:RadRibbonBar ID="RadRibbonBar1" runat="server">
    <telerik:RibbonBarTab Text="Tab 1">
        <telerik:RibbonBarGroup Text="Group 1">
            <Items>
                <telerik:RibbonBarButton ID="rbb1" runat="server" Text="Button 1" />
            </Items>
        </telerik:RibbonBarGroup>
    </telerik:RibbonBarTab>
</telerik:RadRibbonBar>
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>

RibbonBar.Master.vb

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Me.Page.IsPostBack Then
        Response.Write(DateTime.Now & "-RibbonBar.Master Not IsPostBack<br />")
    Else
        Response.Write(DateTime.Now & "-RibbonBar.Master IsPostBack<br />")
    End If
End Sub

RibbonBar.aspx (Using the RibbonBar.Master)

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

    <telerik:RadButton ID="btnRibbonBar" runat="server" Text="RadButton">
    </telerik:RadButton>

</asp:Content>

RibbonBar.aspx.vb

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Me.Page.IsPostBack Then
        Response.Write(DateTime.Now & "-RibbonBar.aspx Not IsPostBack<br />")
    Else
        Response.Write(DateTime.Now & "-RibbonBar.aspx IsPostBack<br />")
    End If
End Sub
Private Sub btnRibbonBar_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnRibbonBar.Click
    Response.Write(DateTime.Now & "-btnRibbonBar_Click<br />")
End Sub

If you put a break point on each of the subs, you will see that when you click the button, the Page_Load events in the aspx and master page are hit, then the click event for the button, then the Page_Load events in the aspx and master page are hit again.

Thanks for your time,
Gordon

Hi Gordon,

We recently fixed similar problems, caused by some img dom elements without a src, which caused additional requests to the currently loaded page. Could you, please, share in which browser does that reproduce?
Thanks.

This happened when we went to debug using IE9.  We added break points in both of the Page_Load events and the button click event.  The project was created in Visual Studio 2010 and targeted the .Net 4.0 framework.

Thanks,
Gordon

Hi Gordon,

Please, try using the next Latest Internal Build. We have made an attempt to fix the problem and our tests are passing on all known problematic scenarios (including the one you reported).

Please, accept our apology for any inconvenience caused.

Hi, I've just spent a few hours debugging an application only to find that I've got the same problem with the RadRibbon bar causing duplicate postbacks. I checked the release notes for the Telerik.Web.UI_2011_2_721_Dev internal build and it doesn't mention any fixes relating to the ribbon bar control. Can you confirm that this internal build should resolve the postback problem?

Thanks, Ian

Hi Ian Price,

Please excuse us for the inconvenience this issue is causing to you.

We worked on this issue and fixed a lot of different cases. It is possible that we missed some (because there are actually lots of them inside the control), so we will continue fixing those as we find them on the way.

Could you also clarify if the latest problem exists in the same setup or in a different one?

Greetings,
Simon

Simon,
Hi. Sorry, I may have confused you with my previous post. I was actually enquiring as to whether the 721 internal build was supposed to fix the multiple postback problem before I tried it. I've since installed the current Telerik.Web.UI_2011_2_726_Dev hotfix and the multiple postback problem appears to have been resolved.

Thanks, Ian

I use this version Telerik.Web.UI_2011_2_712_Trial_hotfix
I have this issue with RadRibbonBAR :-(

I found Telerik.Web.UI_2011_2_713_Dev hotfix Not Telerik.Web.UI_2011_2_726_Dev hotfix where is this version?

[Ian]

Hi, The current internal build version is 821 (Your account page, Internal build downloads) - this should include the fix for the multiple postback problem.
