I was using the Telerik suite for a project and then upgraded to the most recent version when items in our RadWindows would go blank and FireBug would report a "Telerik is not defined" error. I swept the forums for a solution and everything pointed to the fact that we had to review our web.config or our caching.

Neither was an issue.

However, we solved the problem by removing the CdnSettings variable "TelerikCdn = 'Enabled'" and changed it to "Disabled". It appears that Telerik may not have updated their code in the cloud.

The following is our .NET block and the bold line is what was incorrect.



Hope it helps.

Hi Telerik Team,

i just upgraded my telerik version from Q3 2009 to Q3 2010.
now when i am opening a normal window (not rad window) from javascript, it open the window and automatically minimising .
it need to reopen agin from windows task bar.
if it is Rad Window , there is no problem.
it is happening when replaced the telerik dll to Q3 2010. if i replace the dll to Q3 2009, it is working ok.
please let me know what the updation i need to do in Q3 2010 version.

below the code i used.

This is very strange, it seems like our main RadTabStrip (used for navigation) does not seem to remember it's ViewState, even though it is set to true, and all other controls in the samce User Control has working viewstates. You can see this as changing the SelectedIndex doesn't seem to have any effect (all settings seem to reset to those in the .ascx file), and that events like Init() is called on every postback.

Any ideas what to look for here? Don't really know where to start since ViewState is enabled and working for eveything else? Tried experimenting with AutoPostback etc but that doesnt seem to have any effect.

I am using the RadUpload control along with the Rad Progress bar. This was working fine for more than year. Recently we had to add another HttpModule to track the Url in our website. Since then the Rad Progress bar does not show at all. I even downloaded the latest Telerik demo project and added  a simple TestModule. This also breaks the Rad Progress bar.   

using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Configuration;
 
namespace HttpModules
{
    public class TestModule : IHttpModule
    {
        protected log4net.ILog logger = log4net.LogManager.GetLogger("File");
 
        public void Init(HttpApplication app)
        {
            app.BeginRequest += new EventHandler(OnBeginRequest);
        }
 
        public void OnBeginRequest(Object sender, EventArgs e)
        {
            try
            {
                logger.InfoFormat("TestModule => OnBeginRequest");
 
                HttpApplication app = (HttpApplication)sender;
                HttpContext context = app.Context;
 
                logger.InfoFormat("TestModule => This is just a Test module");
 
                if (IsTelerikRequest(context.Request))
                    return;
 
                string source = context.Request["source"];
 
                if (!string.IsNullOrEmpty(source))
                {
                    logger.InfoFormat("TestModule => source is {0} ", source);
                }
 
            }
            catch(Exception ex)
            {
                logger.Error("Error in Test Module", ex);
            }
        }
 
        private bool IsTelerikRequest(HttpRequest httpRequest)
        {
            logger.InfoFormat("TestModule => IsTelerikRequest (httpRequest.RawUrl : '{0}')", httpRequest.RawUrl);
            return httpRequest.RawUrl.Contains("RadUploadProgressHandler.ashx");
        }
 
        private static bool IsAjaxRequest(HttpRequest request)
        { 
            if (request == null) 
            {
                throw new ArgumentNullException("request");
            } 
            
            return (request["X-Requested-With"] == "XMLHttpRequest") || ((request.Headers != null) && (request.Headers["X-Requested-With"] == "XMLHttpRequest")); 
        }
 
        public void Dispose() 
        {
 
        }
    }
}

Hello,

I am using the trial version of Telerik ASP.NET controls. I came across the following 2 issues:

1. Adding custom command to the raddoc then its images are not appearing on the DocTitleBar.



2. Surprisingly I got error messages on the design window. Plz find the attachment for it.

Can you plz suggested me to do this the better manner ?

I am trying to make a page which operates mostly on the client with radrotator.  you can think of it as a simple slide-show type interface.  radrotator has thumbnails, which switching between index, larger image updates (along with some other things)

I am using hash parameters in the URL to allow users to "bookmark" pages meaningfully, and below is what i see as the relevant javascript code.

i use a boolean "stateHandled" variable which lets the code know whether or not it should look at the hash value and update the page accordingly, or if the state change has already been handled....

thus, if user presses back button, the onhashchange event updates the gui.
on the other hand, if user interacts with the radrotator - the onhashchange event does nothing.

what is REALLY weird is that all of this works fine except for one thing...  the animation of the radrotator is suppressed now for when the user is changing the index via interactions with the radrotator, but the forward/back buttons of the browser work fine (they have animation).



on the other hand, if i make the changes to the above code, having:



then the animations work fine...  (however the logic of the code isn't exactly perfect... the forward/back buttons only work every other hash change)

any ideas?  thanks.

Hi there,

Are you planing to support Telerik RadInput with the RadInputManager?  This is great for standard ASP.Net controls, but what if our page already is using telerik controls?  It would be great to be able to benefit the optimization of the InputManager with Telerik controls as well.

Thanks.

Hi,
I'm struggling to export a radgrid to csv or excel on client side. My grid is declarative created in aspx page and the structure is generated in Page OnInit. There are multiples GridTemplateColumns created with HeaderTemplate and ItemTemplate. Inside the ItemTemplate is a RadioButtonList created.
The problem is that the data from GridTemplateColumns is excluded from generated csv file.
I saw to following post:
http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/radgrid-export-to-csv-for-dynamic-gridtemplatecolumn.aspx
What I'm asking here is maybe something was changed in terms of client side exporting from the date of the previous post.
Thank you
Catalin

I've come across an odd thing happening on my dock's background when dragging an item that exists in a zone on it's own, vs what happens when you drag a widget that has other items in the same dock with it. Screenshots attached will explain further, but basically, it looks like it uses the zone's height when the item's on its own (smallzone.png).
If there's another item/widget under or above the item you're dragging, its background uses the desired output (desiredzone.png).

I've set the MinHeight on the zones to make sure it's more than just a thin band of grey that the user will barely be able to see (in case I can't get around it) but is there a way to make it use the item's height instead of the zone's when there's only one item present? Thanks.

Hi all,

I have a radgrid which is in a radpanel that has a radtoolbar which contains the buttons 'New' and 'Delete'. I managed to write code to select the row in the radgrid once and clicking the delete button in my radtoolbar to trigger the function to delete it from the db. However, I want to be able to also have a double-clicking event whereby when you click twice, it will redirect to another page on my website.

Currently in my radgrid I used the OnSelectedIndexChanged="CaseListRG_SelectedIndexChanged" and in the code behind I will retrieve the id of the clicked row, which is working fine. But because I want to actually click twice to redirect, it doesnt work because when I click once it already triggers OnSelectedIndexChanged="CaseListRG_SelectedIndexChanged". Hence I am unable to do the redirecting.

Is there anyway at all for me to actually do a single click on row and retrieve the case_id of the selected row in code behind and do a double click on row and redirect to another page?

I hope Im making sense? Any advice is appreciated.
