Hi,
as I recently read in Miguel de Icaza's blog the Telerik ASP.NET AJAX Controls now support the Mono framework (see: http://tirania.org/blog/archive/2009/Apr-03.html).
I tried to reach the test page mono.telerik.com but unfortunately I was not able to reach it.
Is it possible to reach it under another url or something?

Best regards,
Ferdinand

Hi all,

I have similar problem with RadGrid, in fact it's just one of many exceptions I get while trying to use Telerik ASP.NET controls with Mono 2.4 (under OpenSUSE + xsp2/Apache, or under WinXP + xsp2).

For instance, I tried to reproduce example from http://mono.telerik.com/Ajax/Examples/Manager/UserControl/DefaultCS.aspx , I made an almost exact copy and even used SqlServer database. Then I run it under OpenSUSE + Mono 2.4. Result: I got above InvalidCastException after changing selection in DropDownList. It occured during LoadViewState, so I set EnableViewState on RadGrid to false and, well, new exception showed up:

System.InvalidOperationException: Internal error. Invalid writer object.
  at System.Web.UI.UpdatePanel.RenderChildren (System.Web.UI.HtmlTextWriter writer) [0x00000]
  at System.Web.UI.UpdatePanel.Render (System.Web.UI.HtmlTextWriter writer) [0x00000]
  at System.Web.UI.Control.RenderControl (System.Web.UI.HtmlTextWriter writer) [0x00000]
  at Telerik.Web.UI.RadAjaxManager.Render (System.Web.UI.HtmlTextWriter writer) [0x00000]
  at System.Web.UI.Control.RenderControl (System.Web.UI.HtmlTextWriter writer) [0x00000]
  ...

So, demo on mono.telerik.com is online, but has anybody actually managed to run something with RadGrid, RadAjax, RadTree etc. on his own? I think it would be a good idea to publish mono-ready sources from mono.telerik.com so everybody could check how it works and run it locally. For now it seems to me that 2009.402 is not yet Mono compatible, I just assume that if something that simple as the example above run on Windows, it should also run under Mono with no modifications...

Thanks in advance for any help!

Kind regards,
MJ

Hello all,

Excuse us for the late reply.

Please note that we have modified the RadControls' source a little, so they run flawlessly on Mono. If you are our customer, you can contact us via a formal support ticket and we will send you the modified assembly. Otherwise, we plan to release a standalone trial version of RadControls for ASP.NET AJAX until the end of this week.

@Marcin: The RadControls for ASP.NET AJAX version used on our server is Q3 2008 SP2 (1314).

Hello Daniel,

So what about your plans? It's possible to get a demo version Mono compatible ASP.NET controls?
I'm starting a new project that have to run on Mono/Linux environment and decision which controls will be used is crucial.

Kind regards.

Hello Ivo,

Thanks for your response. I am looking forward impatiently.
I've got a few additional questions. The first is about ASP controls performance and reliability under Mono/Linux environment. Have you done any benchmarks? Or maybe you have some data from your demo http://mono.tererik.com server? I'd be glad if you could provide more details about that. Finally, will it be possible to buy these controls together with source code?

Kind regards
Marcin.

Hi Marcin,

We have not done any extended performance testing specifically for Mono/Linux but this should be something to provide in the future. We will be able to send you an appliance image of the demos if you contact us in a support ticket.

The subscription license includes full source code, priority support and all updates for one year. For more details please refer to the Purchase section on the website or contact us.
