Telerik + Visual Studio 2010 Toolbox = Maddening Problems

Question

Has anyone ever found a solution to either of these problems:

1. When entering any design mode in Visual Studio 2010 (WPF, EDMX, Silverlight, Reporting, etc) I see a message in the status bar like Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage '{2C98B35-07DA-45F1-96A3-BE55D91C8D7A}'... This locks VS for about a minute everytime.

2. Telerik toolboxes have many duplicate controls.

3. Toolbox doesn't show any items when expanded. I think this is because it has too many controls in it.

I believe all of these issues to be related. I think when #1 happens, duplicate controls are added to some toolboxes, which eventually causes #3 to happen.

I'm sick of this and I'm pretty sure it's caused by Telerik's "Rad" stuff. I have 2 dev machines that never did any of this until I installed some rad controls.

Answer 1

I have experienced this once before and the problem was easily remedied, but I think it would be on Telerik to figure out a permanent solution.

It seems that when you update your controls, it maintains instances of the installs (the different versions) Example

I'd assume that if you have installed many updates, the toolbox itself has experienced some kind of issue regarding the variety of versions and thus led to all the problems described there. It's also worth nothing that when new revisions (the Q1/Q2/Q3/Q4 releases) come out, if you update the tools inside VS, your computer may still think the older version is installed on your computer. (Go check "Add/Remove" programs from your control panel and see if you have the latest release installed like here).

When I fixed this problem on my computer I uninstalled the old release (which was a Q1 release). This got rid off all the updates that I had installed for Telerik during that quarter. I then installed the Q2 release (which was the most recent download from the site) and simply loaded up my apps and converted them to the latest release when prompted.

Hit me back with an update if you try the reinstall of the most recent release from Telerik.
