Hi
"sys.webforms.pagerequestmanagerserverexception: An unknown error occurred while processing the request on server. The status code returned from server was: 12029"
I get this error sometimes when my site is running in production i have searched on google for this error which says it occurrs when internet is disconnected and request from web site is sent and they tell the following script to add to show the custom error
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
   if (args.get_error() != undefined)
   {
       if ((args.get_response().get_statusCode() == '12007') || (args.get_response().get_statusCode() == '12029'))
       {
       //Show a Message like 'Please make sure you are connected to internet';
       alert('Please make sure you are connected to internet');
        args.set_errorHandled(true);
       }
   }
}

Media Manager upload problems

I'm having a few problems with the media manager, I'm using the Q2 version and my code looks like this:

    
            <telerik:RadEditor 
        
            height="500px" 
        
            width="700px" 
        
            ID="PageEditor"  
        
            Runat="server"

            ShowHtmlMode="True"

            ConvertToXhtml="True"

            ContentAreaCssFile="editorStyles.css"> 
        
            <Content> 
        
            </Content> 
        
            </telerik:RadEditor>

Image manager and Document manager work fine but when I try to upload .mov or .avi files I get a message saying "The extension of the uploaded file is not valid" even though it is and is listed under file extenions allowed on the upload window. Any ideas? this is driving me mad and I really need to get it fixed asap

            {  
        
                background: url('../Images/bookstore_activetab.jpg') no-repeat;

                text-align:left;  
        
                width: 175px;  
        
                height: 28px;  
        
                color: #5b3b23;  
        
                padding-top: 10px !important;  
        
            }  
        
            .selectedtab  
        
            {  
        
                background: url('../images/bookstore_inactivetab.jpg') no-repeat;  
        
            }  
        
            .hovertab  
        
            {  
        
                color: #ad9d91;  
        
            }  
        
            .pageview  
        
            {  
        
                background-color: #EBF5F6;  
        
            }

My problem is that when I have ScrollChildren on, my tabs disappear. I believe that it is because I am not using a standard skin. Can you tell me what other css styles I need to define in order to use ScrollChildren with my custom tab css.

Thanks.
Dan

Adding multiple items using DataNavigateUrlFormatString

Hi,

I have a grid and a date range parameter and need to send those date parameter values through the DataNavigateUrlFormat. How can I do this without hardcoding those values and using the date parameter values (dynamic values)

Example: In the column mentioned below I want to pass “From Date” and “To Date” values as part of the query string.

<telerik:GridHyperLinkColumn DataNavigateUrlFields="EmailCampaigns" UniqueName="EmailCampaigns"

DataNavigateUrlFormatString="EmailTrackingBreakup.aspx?MailType={0}&FrmDt=01/01/2009&ToDt=05/31/2009" DataTextField="EmailCampaigns"

HeaderText="Email Campaigns" SortExpression="EmailCampaigns">

</telerik:GridHyperLinkColumn>

Thanks,

[Solved] Error sending JSON object to AjaxManager via AjaxRequest

Hi,

I have bumped into a small issue regarding sending a JSON object to AjaxManager from client side javascript.

I'm trying to send this string representation of a JSON object:

    
            {'cmd':'Rebind','data':[{'newid':5},{'newname':'test'}]} 
        

Client side script calling ajaxRequest() thus:

    
            function refreshView(args) { 
        
                var ajxmgr_id = '<%= RadAjaxManager.GetCurrent(Page).ClientID %>'; 
        
                var oAjxMgr = $find(ajxmgr_id); 
        
                var jsonArgs = JSON.stringify(args); 
        
                oAjxMgr.ajaxRequest(jsonArgs); 
        
            }

where "args" is the JSON object.

Error message received when passing this JSON object:

Sys.WebForms.PageRequestManagerServerErrorException: Type System.String not supported for deserializing a matrix.

This is the full error message I receive (excuse the Norwegian :P )

As you can see the JSON object has a nested array in it ('data':[...]). Are there limitations to the complexity of the JSON strings I can pass to ajaxRequest()?

The problem is circumvented by simplifying the JSON object to a flat structure; i.e.:

    
            {'cmd':'Rebind','newid':5,'newname':'test'}

With same client side script above, there are no errors and everything works fine.

Is it possible to pass complex nested JSON objects as strings or can I only send flat structured {"key", "value", ...} type objects?

I'm using the lastes RadControls for ASP.NET Ajax (2009.2.701.35)

Ernst
