Problem with Update Version telerik in RadMenu

[Daniel Botero Correa]

Hello,

I did an upgrade of the RadControls Telerik ASP.NET and I have a problem with the RadMenu.

when I do click in the menu's item, I get this error (Before it worked very good).

Sys.WebForms.PageRequestManagerServerErrorException: Specified cast is not valid.
[Break on this error] Type.registerNamespace("Sys.WebForms")...UI._UpdateProgress",Sys.UI.Control);

Error: image1.jpg

Thanks.

Hello Daniel,

This seems to be a server error that occurs during an AJAX update. Can you please try attaching a debugger and seeing the stack trace of the exception? It would greatly help us in tracking down the problem.

Kind regards,

Hi Dimitar Milushev,

The error occurs in the " } finally {" and i cannot see the " catch() ", so I cannot get the stack trace of the exception or I don't know how to do it, can you explicate me?, the code is in one line and it's impossible to put a break point in this place.

I was be able to get this information:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException:
Specified cast is not valid.

and seemingly it occurs in this code:

try{a._webRequest.completed(Sys.EventArgs.Empty)}finally{if(a._xmlHttpRequest!=null){a._xmlHttpRequest.onreadystatechange=Function.emptyMethod;a._xmlHttpRequest=null}}}};

I hope this information will be able to help you and you will be able to help me!!

Thanks,

Hi Dimitar Milushev,

I removed the RadMenu's AJAX UPDATE CONTROL, and i got the stack trace of the exception, seemingly the RadMenu is not the problem, the problem is the RadSlider which is contained in the RadPageView which is associated with each RadMenuItem of the RadMenu.

The stack trace of the exception:

Erreur du serveur dans l'application '/WebSite'.

I must commnet in the RadSlider's forum this error? or can you explain me, why it occurs?

The ASP code of the RadSlider is:

<telerik:RadPageView ID="RadPageView2" runat="server" Width="350px">
                    <div><table>
                        <tr>
                            <td>
                                <telerik:RadSlider ID="week" runat="server" AnimationDuration="400"
                                Height="70px" ItemType="item" Width="350px" Value="8"></telerik:RadSlider>
                             </td>
                         </tr>
                     </table></div>
</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView1" runat="server" Width="350px">
                        <table>
                            <tr>
                                 <td>
                                    <telerik:RadSlider ID="month" runat="server" AnimationDuration="400"
                                     Height="70px" ItemType="item" Width="350px" Value="3"></telerik:RadSlider>
                                 </td>
                             </tr>
                         </table>
</telerik:RadPageView>

And the C# code of the RadSlider is:

    private void initialize_month()
    {
        try
        {
            month.Items.Add(new RadSliderItem(managerClient.MonthLabel(DateTime.Now.AddMonths(-2).Month.ToString(), SourceFileClient), DateTime.Now.AddMonths(-2).ToString()));
            month.Items.Add(new RadSliderItem(managerClient.MonthLabel(DateTime.Now.AddMonths(-1).Month.ToString(), SourceFileClient), DateTime.Now.AddMonths(-1).ToString()));
            month.Items.Add(new RadSliderItem(managerClient.MonthLabel(DateTime.Now.Month.ToString(), SourceFileClient), DateTime.Now.ToString()));
        }
        catch (Exception ex)
        {
            //TODO ECRIRE LOG

        }
    }

    public void initialize_week()
    {
        try
        {
            for (int i = 7; i >= 0; i--)
            {
                String value =
                        DateTime.Now.AddDays((-7) * i).ToString();
                RadSliderItem item = new RadSliderItem(
                    DateTimeTreatment.GetWeekNumber(
                        DateTime.Now.AddDays((-7) * i)).ToString(), value);

                if (i == 0)
                {
                    //item.Selected = true;
                }
                week.Items.Add(item);
                week.DataBind();
            }
        }
        catch (Exception ex)
        {
            //TODO ECRIRE LOG
        }
    }

In before version, it worked very good, but now, when I upgraded the Telerik ASP.NET's dll, it not works!!

Can you help me? I didn't find the problem in t he code.

Thanks.

Hi Dimitar Milushev,

That's it... It works, I found the problem!!

The problem was in the RadSlider with ID week. I had put into tags Value = 8 and I generate only 7 RadsliderItem, in the before version there wasn't problem and that was permitted, but not seemingly in the last version (

assembly

 

="Telerik.Web.UI, Version=2010.1.309.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"

 

)

Cordially,
Daniel Botero Correa
