"Cannot access a disposed object. Object name: 'Designer Frame.'"

Help.

I have been working with VWG for some time now, and I am starting to get deeper into some of the components. Just recently, I added a ListView (this is the only change I think that is significant).

Now, Visual Studio 2010 consistently goes into an infinite look of dialog boxes, not when my app is running, but when I'm in development. Also the designer screen for the form starts to fail. Any thoughts?

Re: "Cannot access a disposed object. Object name: 'Designer Frame.'"

Hi gdeatz,

Welcome to Visual WebGui

If you are using Visual WebGui framework "with sources" type of installation, you must follow the direction in this article here, for some extra assemblies that you will have to register on your project to be able to use the designer. Look at the "Extra refrences required" section.

Please let us know if this does not apply to your case.

If it does not, please consider emailing your problematic project to support for us to take a look. If you choose to do so, please clean your project, zip it and then email it to the support email address (see my signature) along with the full Http reference to this thread. Please also post here when you have sent it.

Hope this helps,

Palli

How do I check if I have a "with sources" installation? I don't think I do, but hey, you never know.

Hi Greg,

You should see from the name of the .MSI file you downloaded and installed, and you should see in the installed programs in Control Panel.

Re: "Cannot access a disposed object. Object name: 'Designer Frame.'"

It's not a "with sources" build based on your post.

The project itself is rather complicated, so I can't just send it to you.

I've tried created a very simple project to reproduce the problem, but so far no luck. The symptom is this:

I have a relative complex form, lots of panels and a listview. Actually it's not that complex, but it *does* have more than just a couple of controls on it.

1. When I get compilation errors while modifying the code of the form, often the Designer decides it doesn't want to display any more. So, I close and reopen the designer and life goes on.

2. If the Designer is open when my machine goes to Sleep, when I wake my machine up, I get the "Cannot access disposed object." error.

Windows 7, VS 2010 10.0.30319.1 RTMRel.

Are there recent patches of VWG to apply?

Thanks,

Greg
