[RESOLVED] Control Resizing

[Bill Crawley]

Hi All,

In VB6 there was a Method called resize on a form that would allow me to programatically change the width, height etc of controls on a form based on the forms dimensions. Typically used when a user Drags the edge of a form to make it larger.

I could not find a Resize event on my form (Winforms).

It appears that I need to use something like a FLowLayout Control. So I have placed a flowlayout control on my form and then placed a treeview and grid control on that. However, I still seem not to be able to resize the control accourdingly.

COuld someone please point me in the direction to resize controls on a form during runtime when the user decides to manually increase or decrease the size of the form.

use either the dock property, or anchor property to automagically layout your control.

In VS 2005, most 'Winform' controls have a Resize event which is accessed in the Properties window. A System.Windows.Forms.Form also has ResizeBegin and ResizeEnd events.

I've used both approaches. I'll always try to use multiple panels and use anchors until things just don't work the way I want, and then I'll switch to the "do it my way for this UI" approach. Of course, I usually just make my dialogs big and not resizable.

Maybe you missed the Resize event (in VS 2005, it's grouped with the Property Changed events).

Hi All,

I've got the controls on 2 flowlayout controls. and they stay positioned. When resizing the form I cannot shrink the form to less than the default size (good), however i haven't figured out when I 'grow' the form how to increase the controls proportionally. A further problem, is if I expand the form from the Left hand edge, the controls stay in place and do not follow the left edge of the form as I'd expect.

I Guess I need to use 'Zips' suggestion, how do I declare the ResizeBegin event in C#?

Once way to have the IDE write the method signatures for you is as follows....


Click on the properties tab in your IDE

Click on the form you wish to resize controls for. The properties of the form are now displayed in the properties tab.

Switch to the events for the form by clicking on the 'Lightening bolt' icon at the top of the properties tab. All form events are now displayed.

Find the resize event in the tab. Double click in the empty space next to the event name.

The IDE will write the method signature for that event & automatically wire up the event in your forms' InitializeComponent routine.

Thanks DMorley. So it looks as though I just need to write my own routine to do whatever I want happen and then call that routine in the correct event.
