How can I resize the height of two listviews with respect to one another within a windows form. with-CodePudding

I have a windows form with two ListViews, one on top of the other. I need a way to be able to resize the height of the top ListView and as the height of the top ListView gets bigger the height of the bottom ListView gets smaller. Without resizing the windows form itself. Any help would be greatly appreciated.

CodePudding user response：

So you can dock one element at the top in a panel , and use the fill property of dock to dock the second one in the same panel

CodePudding user response：

You can achieve the outcome you want using SplitContainer with Orientation=Horizontal.

Add the SplitContainer to the MainForm and dock it.

Add ListViews and dock them.

TEST

Class for ListViewItem

// Class for ListViewItem
public class Employee
{
    public static implicit operator ListViewItem(Employee employee)
    {
        return new ListViewItem(new[] { employee.First, employee.Last });
    }
    public string First { get; set; }
    public string Last { get; set; }
}

Initialization

public partial class MainForm : Form
{
    public MainForm()
    {
        InitializeComponent();
    }
    protected override void onl oad(EventArgs e)
    {
        base.OnLoad(e);
        listViewTop.View = View.Details;
        listViewBottom.View = View.Details;

        listViewTop.Columns.Add(nameof(Employee.First), 200);
        listViewTop.Columns.Add(nameof(Employee.Last), 200);

        listViewBottom.Columns.Add(nameof(Employee.First), 200);
        listViewBottom.Columns.Add(nameof(Employee.Last), 200);

        listViewTop.Items.Add(new Employee{ First = "Tom", Last = "Cruise", });
        listViewTop.Items.Add(new Employee{ First = "Tom", Last = "Holland", });
        listViewBottom.Items.Add(new Employee{ First = "Tom", Last = "Hanks", });
    }
}

Screenshot

Now the two ListView objects size in coordination with each other by dragging the Splitter.
