rad controls 2.7.0 upgrade to VS2010

[Bilal]

We recently upgraded a website solution from Visual Studio 2008 til Visual Studio 2010 and .NET 4.0 run time.

We are using rad controls 2.7.0.

After the deployment we started getting this JavaScript run time error "Object doesn't support this property or method "Dispose".

Webpage error details

I cannot reproduce the problem on my development environment. But I can reproduce it on my test environment where I'm running an IIS site.

I looked in my bin folder and I found RadComboBox.Net2.dll (version 2.7.0.0).

I'm new to rad controls. Do we need to upgrade the rad controls? Is there a an upgrade guide?

Any help is appreciated.

I found this thread http://www.telerik.com/community/forums/aspnet-ajax/ajax/radajax-broken-in-vs-2010-beta-2-in-master-content-pages.aspx that has workaround of setting ClientIDMode property of the Page to "AutoID". It worked on my test environments.

1st test environment: Microsoft Windows Server 2003 R2, .NET 4, IIS6
2nd test environment: Microsoft Windows Server 2008 R2, NET 4, IIS 7.5

However it is still not working on our partner test environment: Microsoft Windows Server 2008 Standard, .NET 4, IIS 7.0

It's a puzzle and any help is appreciated.

Hi Bilal,

Take a look at the following help article explaining on Migrating from RadComboBox Classic to ASP.NET AJAX version: http://www.telerik.com/help/aspnet-ajax/combobox-overview-migrating.html.

Also, the following blog post contains important tips on how to update RadControls for ASP.NET AJAX to another version: http://www.telerik.com/support/kb/aspnet-ajax/general/updating-radcontrols-for-asp-net-to-another-version-or-license.aspx.

All the best,

Hi Telerik

I have upgraded my Rad controls to version 2012.1.411.

Now I'm having layout problems. My custom skins are not active.

I have a folder RadControls in my website root.

My skin folder structure looks like this:

RadControls  -> Combobox -> Skins -> {Skin name}

My {skin name} folder contains images e.g. DropArrow.gif and Styles.css.

I checked Telerik.Web.UI.XML. It says that the default location for Toggle Image is ~/RadControls/ComboBox/Skins/{SkinName}/DropArrow.gif

But even though I set ShowToggleImage="true" on RadComboBox it's not appearing.

Can you help?

Thanks in advance.

Hi Bilal,

Make sure that the CSS classes of your custom skins are named properly as it is described in the following help article: http://www.telerik.com/help/aspnet-ajax/combobox-appearance-migrating-skins.html.

The help article linked below might be of help as well for it shows a valid approach to creating your own custom skin: http://www.telerik.com/help/aspnet-ajax/combobox-appearance-creating-custom-skins.html.

Kind regards,
