How to scroll in TabPages/TabControl

Question

I've tabcontrol with 3 pages. Within the tabpages are placed listviews. The listviews can be bigger than the tabpage itself.

I wanna add scrollbars on the tabpages

I tried to solve this with the following source:

  lvwAlbums.Parent = pctlDatabeheer.TabPages[1];
            lvwAlbums.Left = 0;
            lvwAlbums.Top = 0;
            lvwAlbums.Width = pctlDatabeheer.TabPages[1].Width - 35;
            lvwAlbums.Height = 1000;// pctlDatabeheer.TabPages[1].Height;
            lvwAlbums.SmallImageList = iltListView;
            lvwAlbums.FullRowSelect = true;
            lvwAlbums.Anchor = AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top;

 foreach (TabPage _Page in pctlDatabeheer.TabPages)
            {
                _Page.AutoScroll = true;
                _Page.AutoScrollMargin = new System.Drawing.Size(20, 20);
                _Page.AutoScrollMinSize = new System.Drawing.Size(_Page.Width, _Page.Height);
            }

But the scroll are not shown. What do I wrong?

Can anybody help me?

Thank yopu for your help.

How do you do that? With Scrollable = true; I didn't see any difference. — user1531040

It is the anchoring. Remove your anchoring to the bottom. Please remember to upvote and accept if this helps you. — Michael Mankus

I created a new Visual Studio WinForms project. Kept the form designer completely empty and used your code:

public Form1()
{
    InitializeComponent();

    // Make TabControl
    TabControl tabControl1 = new TabControl();
    tabControl1.TabPages.Add(new TabPage());
    tabControl1.TabPages.Add(new TabPage());
    tabControl1.Dock = DockStyle.Fill;
    this.Controls.Add(tabControl1);

    // Make long ListView and add to first tab
    ListView listView1 = new ListView();
    listView1.Location = new Point(0, 0);
    listView1.Height = 1000;
    tabControl1.TabPages[0].Controls.Add(listView1);

    // Your code
    foreach (TabPage _Page in tabControl1.TabPages)
    {
        _Page.AutoScroll = true;
        _Page.AutoScrollMargin = new System.Drawing.Size(20, 20);
        _Page.AutoScrollMinSize = new System.Drawing.Size(_Page.Width, _Page.Height);
    }
}

Works perfectly fine. I suspect you have something else wrong but I can't see that or troubleshoot it without seeing your code.

EDIT: Now that you posted some more code, your issue is with your list box:

lvwAlbums.Parent = pctlDatabeheer.TabPages[1];
lvwAlbums.Left = 0;
lvwAlbums.Top = 0;
lvwAlbums.Width = pctlDatabeheer.TabPages[1].Width - 35;
lvwAlbums.Height = 1000;
lvwAlbums.SmallImageList = iltListView;
lvwAlbums.FullRowSelect = true;
// Here is the issue!
// Do not anchor to the bottom or scrolling won't work
lvwAlbums.Anchor = AnchorStyles.Bottom | AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top;

Don't anchor the control to the bottom. That is causing you the issue. You cannot anchor to the bottom and then scroll. The other anchors are fine.

Thank you. But it is much complexer. I've a panel added as parent for the listview. (For so far). But the TabControl is bigger than the form. Now I'm looking for the reason why?
