Problem with control resizing
- Thread starter simonkue

When the user resizes their form, this triggers for form resize event which I trap and then use the ratio of old size to new size to give me new figures for height, left, top etc for each control.
I then iterate through the controls collection applying the new figures. This is fine for those controls shown on the visible tabs. However, the controls on the hidden tabs are moved away from their tab over to the left most side of the form.

On examination, the controls on the hidden tabs are given large negative values for their "Left" property and this produces the unwanted result.
Does anyone know of a way to effect a resize on all a forms controls when some are placed on a hidden tab?
p.s. Sorry about the post spread over a few mini-posts but for some reason I couldn't post this at one time!

This was posted a few months ago by nickdell: It may be useful.
I think when a control is made invisible it is moved off the screen. Hence the negative values.

I don't understand why you have to resize controls that are hidden, by the way--if they're hidden, why do we care what size they are?. Also, you may want to have a look at Golom's excellent thread222-1295329, which is a class to handle resizing.

BobRodes,
The controls are "hidden" because the relevant tab that they are on is not shown at the point of the resize. After resizing, I should be able to go to that tab and see the relevant controls resized. However, they are gone! Irrespective of the tab that is shown when I resize, those controls resize correctly. All those not shown (for which I use the term "hidden") are not positioned correctly after the resize.
SBerthold, the tab controls are already inside frames. However, the controls on each tab are not within frames. I will try this to see if it makes a difference.
Thanks to you both so far.

If they remain hidden, then Bob is right. If you make them visible depending on a user's selection (w/o reloading), then I would in most cases make them always visible but set the Enabled property to False.
I always use a Frame on a SSTab's Tab to hold all controls. It does prevent some other bugs from happening as well (at least in the past)...
