Assuming you re using winforms  default panel components does not offer you a way to disable the horizontal scrolling components  A workaround of this is to disable the auto scrolling and add a scrollbar yourself   ScrollBar vScrollBar1   new VScrollBar    vScrollBar1 Dock   DockStyle Right  vScrollBar1 Scroll     sender  e    gt    panel1 VerticalScroll Value   vScrollBar1 Value     panel1 Controls Add vScrollBar1     Detailed discussion here

Below is the code that implements custom vertical scrollbar  The important detail here is to know when scrollbar is needed by calculating how much space is consumed by the controls that you add to the panel   panelUserInput SuspendLayout    panelUserInput Controls Clear    panelUserInput AutoScroll   false  panelUserInput VerticalScroll Visible   false      here you d be adding controls  int x   20  y   20  height   0  for  int inx   0  inx  lt  numControls  inx              this example uses textbox control     TextBox txt   new TextBox        txt Location   new System Drawing Point x  y          add whatever details you need for this control        before adding it to the panel     panelUserInput Controls Add txt       height   y   txt Height      y    25    if  height  gt  panelUserInput Height        VScrollBar bar   new VScrollBar        bar Dock   DockStyle Right      bar Scroll     sender  e    gt    panelUserInput VerticalScroll Value    bar Value         bar Top   0      bar Left   panelUserInput Width - bar Width      bar Height   panelUserInput Height      bar Visible   true      panelUserInput Controls Add bar     panelUserInput ResumeLayout        then update the form this PerformLayout

Try this instead for  only  scrolling vertical   auto scroll needs to be false before it will accept changes   mypanel AutoScroll   false  mypanel HorizontalScroll Enabled   false  mypanel HorizontalScroll Visible   false  mypanel HorizontalScroll Maximum   0  mypanel AutoScroll   true

AutoScroll is really the solution  You just have to set AutoScrollMargin to 0  1000 or something like this  then use it to scroll down and add buttons and items there

Panel has an AutoScroll property  Just set that property to True and the panel will automatically add a scroll bar when needed
