❔ Panel scroll bar only vertical

Hey guys, small question: I got a form that has a panel inside. I am adding Buttons into that panel. I have a fixed size of the form and panel both Height = 600; I want a vertical scroll only no horizontal

private void InitializeAndAddPanel()
{
    panel.FlowDirection = FlowDirection.TopDown;
    panel.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    panel.Dock = DockStyle.Fill;
    panel.AutoSize = false;
    panel.AutoScroll = true;
    Controls.Add(panel);
}
private void AdjustFormAndPanelContentsSize()
{
    SetWidthForAllControls(panel.Controls);
    panel.Height = Math.Min(MaxHeight, accumulatedControlsHeight);
    Height = Math.Min(MaxHeight, accumulatedControlsHeight);
    Width = Math.Max(Width, maxControlWidth);
}

I call the first method first and then the 2nd method in the init method

private void InitializeAndAddPanel()
{
    panel.FlowDirection = FlowDirection.TopDown;
    panel.Anchor = AnchorStyles.Left | AnchorStyles.Right;
    panel.Dock = DockStyle.Fill;
    panel.AutoSize = false;
    panel.AutoScroll = true;
    Controls.Add(panel);
}
private void AdjustFormAndPanelContentsSize()
{
    SetWidthForAllControls(panel.Controls);
    panel.Height = Math.Min(MaxHeight, accumulatedControlsHeight);
    Height = Math.Min(MaxHeight, accumulatedControlsHeight);
    Width = Math.Max(Width, maxControlWidth);
}

I call the first method first and then the 2nd method in the init method

I added the pictures how it looks like. I thought the items will be added vertically with the TopDown property set. What am I missing?

panel.FlowDirection = FlowDirection.TopDown; I changed this line to: panel.FlowDirection = FlowDirection.LeftToRight; and now I get the vertical Scrollbar and the items are added from top to bottom. I am super confused why it works like this??

a flow panel is not just a simple panel are you sure you want to use that?
