Hello,

I've had issues using Telerik for WinForms for a couple of weeks.

I thought I had cured it all last week when I updated my Telerik Control Panel and then updated the suite of controls.

The WinForms app I am working on will not allow me to add any Telerik controls to any Telerik form.

I tried repairing the Telerik WinForms components which didn't work.

I then uninstalled the Telerik WinForms components and re-installed them. Everything appears to install fine but my project will still not allow me to add controls (I can add RadForms though).

Every time I try to add ANY control I get a messagebox saying: "Failed to created component Rad.... The error message follows"....

Why is trying to re-add a reference to Telerik.WinControls.UI every time a new control is placed onto a form?

I am running Windows7 64-Bit - The references in my app are:

Telerik.WinControls

Telerik.WinControls.UI

TelerikCommon

Paths to files are:

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\Telerik.WinControls.dll

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\Telerik.WinControls.UI.dll

C:\Program Files (x86)\Telerik\UI for WinForms Q1 2016\Bin40\TelerikCommon.dll

Which are the latest downloads via Telerik Control Panel this afternoon.

 

Has anyone else experienced this issue? It's holding me up a lot.

Thanks.

Hello Martin,

Thank you for writing back.

This message is shown when the references in your project are different than the references installed in the GAC. The following article shows how you can resolve this: Failed to create component design time exception. 

Do not hesitate to contact us if you have other questions.
