Managing Autoscroll

My Project is currently in C# Winforms.
I have a custom control that I am inserting on a flow layout panel.
I also have a header that fits above the Flow Layout.
I would like the flowlayout to scroll on the vertical axis while the whole panel scrolls along the horizontal axis.
The problem I am having is that the flowlayout when autoscroll is set to true makes use of both horizontal and vertical scroll
I need the header to scroll horizontally at the same time as the flowlayout but not show its own horizontal scrollbar. I also need the header to stay at the top of the Panel when the flowlayout scrolls vertically.
Thanks for the help
I have been trying out different combinations of autoscroll, wrapcontents and Autosize.

Set panel to fill but the height is scrollable in windows forms

Well, I have a panel that contain some forms. I set panel Dock to Fill because it will be good when window maximized. I set the minimum size of panel too because the contents/forms quite be long to bottom.
Sadly, the scroll bar not shown even I set AutoScroll to True and set AutoScrollMinSize. How to configure this properly?
Let's say I have window height size only 300px but the panel (in window) that contain my forms have height about 600px. I need to always show the scroll bar.
Thanks in advance

Thanks all, I finally figured out what's wrong. I don't need set the MinimumSize of panel
Properties of Panel
Dock: Fill
AutoScroll: true
AutoScrollMinSize: 600px (Height)
It will be automatically force the panel to follow AutoScrollMinSize instead MinimumSize or default Size.

Make sure you don't have any child anchord to the right of the panel, as showed in MSDN documantation:
"There is currently a limitation in Windows Forms that prevents all
classes derived from ScrollableControl from acting properly when both
RightToLeft is enabled and AutoScroll is set to Yes. For example,
let's say that you place a control such as Panel—or a container class
derived from Panel (such as FlowLayoutPanel or TableLayoutPanel)—on
your form. If you set AutoScroll on the container to Yes and then set
the Anchor property on one or more of the controls inside of the
container to Right, then no scrollbar ever appears. The class derived
from ScrollableControl acts as if AutoScroll were set to No.
Currently, the only workaround is to nest the ScrollableControl inside
another ScrollableControl. For instance, if you need TableLayoutPanel
to work in this situation, you can place it inside of a Panel control
and set AutoScroll on the Panel to Yes."

C# FlowLayoutPanel scrollBar

I'm making an instant messaging application in C#. The problem that I'm facing right now is that for the contacts list I've made a custom control extendinguserControl, which contains aFlowLayoutPanel`.
That panel will contain a list of userControls. I want to customize the VscrollBar, but no chance (not possible). Instead I have this genius idea to hide the VscrollBar from the FlowLayoutPanel, and make simple buttons (UP and down events). For this everything worked like a charm, but when I tried to hide the VscrollBar by making the property autoScroll = false , the buttons stopped working.
How can I hide the VscrollBar?

If you want to hide the the vertical bar, there are some possible solutions. ..
You could make an event for resize, controls add, controls remove and set all the child controls' width to flowlayoutpanel.width -20
You could add a panel to the flowlayoutpanel and set it to autosize and make the panels may width to flowlayoutpanel.width-20.
You could check if the width of the flowlayoutpanel is bigger than its real width (means vscrollbar appeared) , and resize the children that it'll/ld hide again
and if you are sure that your controls are smaller than the flowlayoutpanel's width, you simply could create a panel which covers the vertical bar. (use .BringToFront() to put it before the flowlayoutpanel's scrollbar)
I hope that I understood and perhaps have solved the problem

C# Form does not show scrollbar while control is wider than the view area

I have a wide control. I've set its width hardcoded to 2000. When I drag this control to a form with AutoScroll set to true, I don't see any scrollbars even though the form width is less than 2000.
Why is the horizontal scrollbar not visible? What do I have to do, to make the scrollbar visible?

A Frame Inside Of A Winform?

I'm not sure what it's called in the land of WinForms, but in web development terms, I'm looking for a frame type element that can be added to a winform.
I want a panel that is anchored top,bottom,left,right but if the form the panel is resized to a smaller size than the elements in the panel, scroll bars will appear around the panel allowing the user to see the contents of the panel without expanding the form.
I hope that makes sense, and that such a thing exists.
Thanks!

Yes, a Panel control. Set AutoScrollMinSize to the minimum size you want before scrollbars appear. Set AutoScroll to True. Set MinimumSize if necessary, it shouldn't be.
The controls inside the panel need to auto layout by themselves so they'll move as necessary when the panel gets smaller. Use their Dock or Anchor properties. If the layout gets complicated then switch to a TableLayoutPanel or FlowLayoutPanel control.

What about a panel? System.Windows.Forms.Panel

You are looking for a "Panel" control. Just set the "Dock" property to get docking going..

You add a Panel to your form and set Panel.Dock = Fill. Your Panel will auto-resize when you resize the form.
Set Panel.AutoScroll = True
Then, you add controls to your Panel. Set the controls' Dock property accordingly. Now, when you resize the form, scrollbars will appear if controls are covered up.

There are a couple of different panels in the standard windows controls that do what you want... just look in the toolbox when editing a windows form, under 'container'
What do you want it to contain? A web page, or just windows form controls?
