Controls get hidden in designer after debugging

Hello,

I have some basic controls (e.g., checkboxes, textboxes,listboxes, etc)in a nested tab control (one tab control on the tab page of another tab control) and when I debug (F5) my application, everything looks fine. However, when I exit the application and am dumped back into the IDE designer, some of the controls have "disappeared". Sometimes there is a dotted line around their bounding box, as if they're selected but behind something.

I can't find out why the controls disappear, where they go, or how to get them back. The only way I know to get them back is to restart Visual Studio 2005. I don't have any code that hides or unhides controls and it's my understanding that all controls should be shown in the editor anyway, even if their visible property is set to false.

Any help would be appreciated, as this is very annoying and is really slowing down my development work.

Thanks,
Neville

Hi NevilleBonwit,

Base on my understanding, you can see the controls on the form in run time but sometime it disappear in design time. Here I want to know more detail about your problem.

1. Did the form is a inherited form?
2. If it is a inherited form, did the nested TabControl added in base form? In other words, the TabControl you can use in the inherited form is actually inherited from the base form.

You can make a simple project to reproduce the problem and send it to me(v-kiqian@microsoft.com). Then I can research it to find a solution.

Sincerely,
Kira Qian

Hello Kira,

You are correct about the behavior.Not all the controls disappear all of the time; some of the controls disappear some of the time.

I don't think it's an inherited form (I just created a newVS project and it was the default form).

I figured out tonight that when I click and drag (e.g., select with a bounding box) over an area where there is a control that is disappeared, it will show up in the properties area, but the actual control graphics in the designer window are still hidden.

Any thoughts?

Thanks,
Neville

Hi NevilleBonwit,

You mean you can select the control but you still cannot see it? Could you please send me the test project? If the problem can occur on my computer, I will raise the issue to the product team.

Sincerely,
Kira Qian
