    hello.

    web parts added by the preview bits will only let you have drag-n-drop in firefox. you can't put them inside an updatepanel and use partial postbacks to refresh their positioning.

    btw, the error you're having...are you sure you're using beta2 and the november ctp? i've just tedted a simple page here and it worked as expected.

    Hi,

     I've got the same problem, but I found out that when I put the line with <fr:WebPartManager> above the <asp:ScriptManager> using <asp:WebPartZone> the error disappears. But when I use <fr:WebPartZone> the error is back.

    My version of Microsoft.Web.Preview.dll is also 1.0.61025.0. (2 nov 2006)

    hello.

    gillou01:

    what makes you say that? i have installed the latest build of the CTP that i could find on ajax web site

    well, the stack error you're getting:

    [InvalidOperationException: Script controls may not be registered before PreRender.]
       Microsoft.Web.UI.ScriptControlManager.RegisterScriptControl(TScriptControl scriptControl) +112
       Microsoft.Web.UI.ScriptManager.RegisterScriptControl(TScriptControl scriptControl) +100
       Microsoft.Web.Preview.UI.Controls.WebParts.WebPartManager.OnInit(EventArgs e) +148
       System.Web.UI.Control.InitRecursive(Control namingContainer) +460
       System.Web.UI.Control.InitRecursive(Control namingContainer) +272
       System.Web.UI.Control.InitRecursive(Control namingContainer) +272
       System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1745
    if you look at the value-added dll with reflector you'll be able to confirm that it doesn't override the OnInit method.

    Hi,

    Luis Abreu is right. I flushed my GAC and delete all copies of Microsoft.Web.Preview.dll's on my computer, restarted IIS, restarted Visual Studio and did a Build all.
    It works!

    Thanx!

    Greetz!

    Hi rinando,

      same problem, what do you meant by flushed your GAC of all copies of Microsoft.Web.Preview and all copies including in the application working on and in C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025?

    I have also come accross this issue and after lots of flushing and rebuilding I found that it actually was a coding issue losing prerender handlers.

    i've detailed it here: http://danielballa.blogspot.com/2006/11/script-controls-may-not-be-registered.html

     

    Cheers,

    Hi All.

      I am getting the same type of error but it happens when using the UpdateProgress tag. I am using ASP.NET Ajax version 1.0.61025. I have the same versions installed on my local machine and on our company's dev box. When I run it on my local box, it works fine, when I publish to our dev box, it blows up with this error. After I remove the updateProgress tag it works fine. Can anyone offer a solution to this?

     

    Code causing the error:

     <asp:UpdatePanel ID="upnlVehiclePrice" runat="server" UpdateMode="conditional">
           <ContentTemplate>
                  <asp:UpdateProgress ID="uprVehiclePrice" runat="server" Visible="true" DisplayAfter="0" AssociatedUpdatePanelID="upnlVehicleSelection">
                          <ProgressTemplate>
                                  Retreiving Vehicle Price...</br>
                                  <asp:Image ID="imgRetrievingVehiclePrice" runat="server" ImageUrl="ajax-loader.gif" />
                          </ProgressTemplate>
                  </asp:UpdateProgress>
         </ContentTemplate>
    </asp:UpdatePanel>

    Check if the microsoft.web.extensions.dll version is the same. Check it in the bin directory of your application or GAC if it is gac-ed and in the temporary asp.net files.

    Also check if the web.config file is identical. 

    Cheers,
    Daniel

    Thanks for your help.

        I did check the dll, GAC, and the temp asp.net folder... all checked out fine which is even more perplexing. Nonetheless, I appreciate the suggestion.
