Auto resizing simple form with two listboxes

Question

I'm trying to make a simple two-panel file manager (such as Total Commander or FreeCommander). So basically just two listboxes/listviews, one on left, one on right.

But I have hard time trying to make it responsive, when user resizes window either from left side or right side. I need those listboxes to change accordingly on main window/form size, but not cover the other one in process.

I tried on both WPF and WinForms. In WinForms, there is just an Anchor property, which probably can't handle resizing on both up/down and left/right, or I don't know how.

In WPF I know there are tons of ways how to do this, but I don't understand XAML at all, so I'm stuck.

If anyone ever faces similar problem and managed to deal with it, or just has an idea, how to make it work, I would welcome any kind of help.

If you're using WinForms, you're looking for the [`TableLayoutPanel`](https://learn.microsoft.com/en-us/dotnet/framework/winforms/controls/walkthrough-arranging-controls-on-windows-forms-using-a-tablelayoutpanel). — 41686d6564 stands w. Palestine, Sep 01 '19 at 10:07

if you are going to create a WPF application, then learn xaml. it is a "must have" skill. `Grid` with 2 `ColumnDefinitions` fits your requirements. — ASh, Sep 01 '19 at 10:31

WPF solution: use a Grid width three columns. One for each ListView and one for the GridSplitter to make both ListView columns resizable.

<Window>
  <Grid>
    <Grid.ColumnDefinitions>
      <ColumnDefinition Width="*" />
      <ColumnDefinition Width="5" />
      <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>

    <ListView Grid.Column="0" />
    <GridSplitter Grid.Column="1" Width="5" />
    <ListView Grid.Column="2" />
  </Grid>
</Window>

But I'm afraid this solution won't safe you from learning WPF and especially XAML.
