flowlayoutpanel and horizontal scrollbar issue

I am using a flowlayoutpanel which have a lot of buttons per logic sake. I'm having an issue of when I resize the window, I'm not I'm not able to see all the buttons lined up horizontally when the window gets smaller. Instead as the window gets smaller, the buttons drops down to the next line. Can anyone help me on how to resolve this issue? I just want the buttons to line up horizontally, when the window gets smaller, have a horizontal scrollbar. Below is what I have.

fLayoutPnl.Controls.Add(btn1);
// snipped adding buttons from 2 to 15
fLayoutPnl.Controls.Add(btn16);
fLayoutPnl.Dock = System.Windows.Forms.DockStyle.Top;
fLayoutPnl.Location = new System.Drawing.Point(0, 10);
fLayoutPnl.Name = "fLayoutPnl";
fLayoutPnl.Size = new System.Drawing.Size(1245, 30);
Solution

  • If you dock the flowlayoutpanel on the top, it take the size of the parent control. So if you want a horizontal scroll, you need to set the AutoScrollMinSize of the form (or usercontrol).

    Otherwise, you can do this : 

    this.AutoScroll = true;    
this.fLayoutPnl.Dock = System.Windows.Forms.DockStyle.None;
this.fLayoutPnl.AutoSize = true;
this.fLayoutPnl.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
this.fLayoutPnl.Location = new System.Drawing.Point(0, 10);
this.fLayoutPnl.Name = "fLayoutPnl";
this.fLayoutPnl.Size = new System.Drawing.Size(1245, 30);
