      Last week I updated my Rad Controls asp.net from 2013.1.417.35 to 2013.2.611.35 with this I have a couple of questions.

    1: When opening a Visual Studio I usually get the notification of any Telerik Updates and select the Get it Now option. This is what I did on the last go around and updated that way. I noticed that doing so it installed the update in the C:\User\AppData\Roaming\Telerik\Updates\Telerik.Web.UI_2013_2_611_Dev_hotfix folder.  Is this the best way, preferred way or the not correct way to update Telerik Controls. I like to keep my controls up to date,

    2: After updating the controls, I continued to work on my project and once finished I moved over to our production server my changes plus the updated DLL's to the bin folder. Everything seemed to work fine until I came to any of the Rad Grids that had significant customizations that I made in which selecting a record caused the loss of all my Session Variables. After a little process of elimination, I found that pulling out the earlier Rad Grid and adding a new one to the page with some changes to how I made those previous customizations solved the problem. Is this error on my part of improper modifications or something I will have to do to all of the Rad Grids that I customized using the older version of the controls. Putting back the older version of the DLL's did not work, but adding an entirely new Rad Grid was my only option. Any suggestions.

    Thanks John.

    About your first question, yes, this is the easiest and most convenient way to keep the assemblies up-to-date. However, there are other options as well. You could download the assemblies from your account home page and then add it manually to your bin folder. Or you could download the installer and then upgrade the whole installation. It is up to you to decide which option to use.

    About your other question, we do not have any breaking changes regarding the usage of Session state in RadGrid. In fact RadGrid does not use any Session state variables or functionality. Most probably the problem comes from wrong customization and you should not need to modify all RadGrid instances in your project.
