horizontal scrollbar does not show - c#

I have listView in tabControll. listView.Scrollable = true and vertical scrollbar appears normally.
After opening the window, horizontal scrollbar does not show. When I minimize the window the scrollbar appears and after maximalization it stays there. I cant see the reason, why the scrollbar is not there when I start app for the first time.
On the bottom there is no component that could be over the scrollbar.

ScrollBar doesn't appear in UserControl with out of bounds content

I've defined a C# UserControl with some control inside and then put it inside a TabView. I've set the main Form that contains the TabView as resizable and gave it a minimum size.
Whenever I enter fullscreen the window appears like this:
but when I resize the window to be at its minimus size, it appears like this:
As you can see, the DataGridView on the bottom of the UserControl is out of bounds and not visible. Is there a way to automatically set a ScrollBar to appear when I resize the page and show the bottom DataGridView?
I tried to set the AutoScroll to true, gave it a minimum AutoScrollMargin and AutoScrollMinSize but still the DataGridView goes out of bounds and no ScrollBar appears. I expected a ScrollBar to appear and the DataGridView to be reachable by using the ScrollBar to scroll down the page.

How to handle a left click on a control's scrollbar?

I have a control (a text editor control) that uses the default scrollbar to scroll the text. However, clicking the scrollbar only makes it scroll a few lines.
I want to handle the scrollbar left click on my own, and make it scroll page down / page up, depending on the click, if it's above the scrollbar thumb, then page up, if it's below the thumb, page down.
TL;DR I want to know how to handle a left click on a default scrollbar and whether the cursor is above/below the scrollbar thumb. I know there's the Scroll event but it occurs after the user has scrolled, I want something like Scrolling.
If by "default scrollbar" you mean the scrollbars that are part of any ScrollableControl (UserControl, etc.), there's no need to handle the click event. The VScrollProperties class already gives you control over this out of the box:
Use ScrollableControl.VerticalScroll.SmallChange to set the distance the scroll should move when the user clicks on the scrollbar buttons (arrows).
Use ScrollableControl.VerticalScroll.LargeChange to set the distance the scroll should move when the user clicks on an empty space on the scrollbar.

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.

Setting Winforms C# panel VerticalScroll.Value property to 0 is not having any effect

I'm having an issue where my scrollbar for a panel on a usercontrol always appears at the bottom.
If I hover the mouse over the tab and cause the control to slide out and be shown, the scrollbar is at the bottom. If I then move the scrollbar to the top and move the mouse off the control (which causes it to hide again) and then move the mouse back over the tab (which causes the control to slide back out) the scroll bar is back at the bottom!
Setting the VerticalScroll.Value property on my panel to 0 is not having any effect - the control still shows at the bottom. Can someone tell me what events might fire when a control slides back into view on an autohide tab or just tell what I could do to solve this issue! I assume that the Paint event is what fires when the control is shown but I'm not entirely sure.
I did notice that in the VS designer that the scrollbar by default is shown at the bottom. Not sure whether this may have anything to do with the issue?
Any suggestions appreciated!
Try this:
scrollingCtrl.VerticalScroll.Value = 0;
scrollingCtrl.PerformLayout();

scroll in usercontrol

In windows forms
I want to activate scroll to my usercontrol,
i activated autoscroll,
but the horizontal scroll is not appearing.
i have kept my control n tablelayout panel..
Help me for the horizontal scroll..
AutoScroll means that the scrollbar(s) will appear when some content sticks out of the Client Area. When you use a TableLayout (with Docking = Fill) then the AutoScroll does not kick in.
Turn of Docking for the TableLayout and set its Width/Height larger than the Form. You will see AutoScroll in the Designer.
