I'm struggling to figure out how do I make a flow layout panel that has strictly just one column and upon scrolling it adds the controls at the bottom of that column and not make a new column and so on while having it wrap the controls. I can get that If wrapcontents = false. For some reason in my case the scroll bar appears horizontally at the bottom and not vertically at the right side.
How do you make it as explained?

I have a ListView inside of a TornadoFX form builder field that can be added to and removed from by some buttons off to the side. However whenever the contents of the list is modified from the buttons, the list moves vertically downwards. The height of the ListView remains the same, but it's almost as if there is padding being generated along the top whenever the content length is modified. The height change is then reset as soon as there is some change in focus, either by clicking on another component in the view, or by unfocussing and refocussing the window.
I've tried to limit the ability for this to happen by enforcing a max height, both on the form field and on the ListView itself, but neither worked.
Using listeners to print out all the values I could think of that would result in this change, I found that the "bounds in Parent" were changing, adding a value of 17 to both the minY and maxY values. I've not been able to determine where this value of 17 comes from.
The current code for the view is here: https://pastebin.com/6qFVvxvP
I also have some images to help visualize what the problem is:

So I'm having troubles making my FlowLayoutPanel work the way I want.
When adding multiple controls to it so that vertical scroll appears and when scrolled to bottom I don't want controls to be touching the bottom border of FlowLayoutPanel.
Padding works properly for all but the bottom side, controls are properly spaced away from the edges of the FlowLayoutPanel, I don't know why bottom is special.
I need a solution that does not include adding invisible/transparent controls to it.
The closest I got to what I want was lowering the clientsize by some amount, but then in that area control doesn't repaint so it shows parts of added controls forever.
Kind of fixed with with larger margins on child controls, so I'm closing this.
I am laying out views using GridLayoutManager which works fine. However I each item in the grid fills the whole width of the column which makes the view having lots of empty spaces hence I want to use wrap_content for the root view of items but its not working. There's still spaces left from the right side of the grid.
Since no one has been able to answer this, I will just outline what I did to sort it. I use ItemDecorator to fill the space between the columns
I am trying to populate my windows form with new controls and data based on what is read from my database. The left side of the form is a static panel which will not need re sizing but I need to create multiple labels on the right side which requires more space. I added the vscroll control but am having trouble increasing the size of the right side of the form.
To use a scroll-bar will require a semi-low-level implementation where you need to always update the view by repositioning the elements, calculating your scroll-bar in relation to total view, what elements would be visible and so forth.
A better solution in this case will probably be to add a Panel control on the right which is docked (f.ex. Fill) and then set the AutoScroll property to True.
This way you leave all the "low level" stuff to the Panel control and you can add and position the elements you need to the Panel's Controls collection instead.
EDITED:
I think we can just draw an image that resemble the grid using this article : drawing in a datagridview Currently creating a way to make the image drawn in tile mode. :)
Each time I develop a datacentric application using VB.NET regardless of how much the data displayed in the datagrid, I always want the grid to display full row of empty data, not just blank panel.
Can we achieve this using VB.NET design time property?
And also, we must not trigger the display of vertical scrollbar this way.. :)
Thanks
You might try doing a screen capture of the dgv when it is full of blank lines and use that as your background. However, you'll have a problem with the vertical lines if they resize the columns. In your picture you don't have any vertical lines so if you don't need them then just erase them and your problem is solved.
There's also the option of using the Virtual Mode. When you set that property to true then you can set the number of visible rows, but you are responsible for telling the dgv what each individual cell is supposed to contain: http://msdn.microsoft.com/en-us/library/2b177d6d.aspx
Or you can just add extra blank rows to whatever datasource you are setting your DGV to.
Use the ScrollBars property to turn the vertical scroll bar off.
