Is it easy to do sliding panels, such as the one show in this video, where the controls are populated dynamically but also expanded/collapsed when the user is clicking the panels. It also allows scrolling if the height of the visible panels is larger than the application height.
Yes.
To answer your next question, the sliding panels are used in your XAML just like any other panel. For some example controls, check this question

I am developing an application that will use touch screens to navigate for use in a warehouse environment.
There is a need to present a list to the users and because this list could be quite long, the user will at some point need to scroll down the list.
As you all know the system scroll bars for panels and textboxes etc is quite small and I would like to know if I can either resize the controls that make up the scroll bar (the little arrows at the top and bottom, and the place holder bar in the scroll bar itself), or if I can create a couple of buttons that can scroll up and down my control for me?
Thanks,
Karl

Check this out:
Winforms - Adjust width of vertical scrollbar on CheckedListBox
Worth mentioning too:
.NET Compact framework - make scrollbars wider
More of the same, but this time with a better solution through the use of the scrollbar control:
Change the width of a scrollbar
Another one in which the guy teaches how to create your own scrollbar control (interesting):
Set the Scrollbar width of a DataGridView
The last one (worth trying):
Is there a way to get the scrollbar height and width for a ListView control
You can add your own scroll buttons and programatically scroll like so:
myPanel.VerticalScroll.Value++;
I need to create a custom control that has an expandable part as a panel and a textbox part. The expandable part is a panel, that will either be visible or invisible. But when the panel is visible/expanded directly under the textbox, I do not want the adjacent controls to shift down below the panel, but the panel should just overlay the controls that are there just under the custom control. How would I implement this in Winforms C# project?
I am open to using user control for this scenario.
Thanks

I think your implementation of expanding and collapsing is not the best, because you are just overlaying the controls instead of hiding them.
One of the disadvantages is that the overlaid controls might by focussed by pressing tab and they might have a value which I think it is out of target.
I would suggest another implementation by creating two panels (one for the header and another one for the content) and when the collapse button is pressed then the content's panel will be hidden by sitting its Visible property to false and its Hight to 0.
I'm new to Windows Forms in Visual Studio, and I am wondering how to automaticly resize controls to the window size.
Say, I have 2 controls in a panel, a List Box and a Button. I want the button to dock to the bottom, and I want the List Box to fit the rest of the space. when the window resizes, the button should be at the bottom (as expected with docking), and the list box should stretch down to the button.
Is there a way to do this without any code?
Thanks.
Dock is pretty easy to use, but I recommend using the Anchor properties instead. Resize your form to a reasonable size in the Designer. Then, place your controls to look the way you want. Then, decide which controls should resize with the form and set the Anchor property as follows:
If you want the control to resize with the form in width, set the Right anchor.
If you want to resize height, set the Bottom anchor.
If you want the control to stay right when the form resizes, unset the Left anchor.
If you want the control to stay bottom when the form resizes, unset the Top anchor.
The problem I have with Docks is that they sometimes act funny when controls are not declared in a specific order, and to get the effect you want, sometimes you have to create extraneous panels just to hold controls.
It really gets messy when you want to maintain the aspect ratio of each control. One way, which is not really up to the mark if you want to get into fixing the details, is to use TableLayoutPanel and use Dock and Anchor wisely to achieve what you want.
Use the dock and fill options on the controls. Look under properties for each object, and containers if they are in any.
You can use SplitContainer
Google for examples. Here is one
Try setting your ListBox's Dock property to Fill.
You'll need to watch for one thing though: by default the ListBox will size itself to display whole list items. If you resize the control so that it displays a partial item it will adjust itself so it will display a complete item. This can make the control appear to lose its 'Dock'ing behavior. The solution for this is to set the ListBox's IntegralHeight property to false, which specifies that the control not resize itself to fit complete items.
typically in java if you have a layout manager of somesort, when you resize the page then the components in that panel will resize accordingly. I think my app is missing some sort of layout manager to control resizing as at the moment everything is just static
Is there a way to make it resize on the changing of the form size? say the user makes the page bigger, then the componenets adjust and so on.
Thanks
.NET has layout managers as well.
Personally, I prefer the TableLayoutPanel for my WinForms apps.
Once you layout the Table (using a combination of static/dynamic sized rows/columns) you add your child controls to the table cells. Once you add your controls, you can dock or anchor the controls to the cell so that they are automatically adjusted when the window is re-sized.
Two main options:
Anchoring. Set your control to "anchor" to the sides of your form. This means that if the form resizes, the control will stay a constant distance from that side. So, if you anchor Top, Left and Right, then your control will stay in the same position, but resize horizontally with the width of the form. Play with it. It'll be obvious.
Docking. Set your control to "dock" to a side of the form, or the center. This is usually done with containers, and it will make the widget take up that entire portion of the form no matter how large it gets.
In Windows Forms you make use of the Control.Anchor property, which will cause the control to adjust accordingly when the window resizes.
To do this with windows forms you use the Anchor and Dock properties of the control
See this for a guide on how to use them
The closest I can think of using is the GroupBox control which has a custom drawing at the top identifying the panel.
Is it doable? I have done independent custom controls like buttons, sliders, color pickers, but not totally sure if this sort of drawing can be done on a GroupBox?
I would need the grouping of a GroupBox or a TabPanel.
Are there any alternatives on the net that I can use?
Just exploring the alternatives before I start doing it.
A technique we used was to create multiple panels docked to the top of a frame and set their height to zero. Then when we wanted to display a panel we set its height correctly. Winforms automatically reflows other panels to accommodate the new one.
You can also create a recurring timer to trigger every few hundred milliseconds that increases the panel's height by a few pixels until it reaches full size. This creates a nice animation of the panel expanding into place.
See how others have done this. Code Project's got a bunch. Try searching there.
I used this one a while ago and liked it:
Windows XP style Collapsible Panel Bar
Why not just create a composite control? Something to the effect of.. 2 panels or a label and a panel or whatever suits your needs. Drawing it wouldn't be all that difficult but seems overly complicated for your desired functionality. Am I completely missing the mark?
