Try This:

private void btnNext_Click(object sender, EventArgs e)
    {
        currentPosition++;
    
        switch (currentPosition)
        {
            case 0:
                LoadControl(new UCMain(this));
                btnBack.Enabled = false;
                btnNext.Enabled = true;
                break;
            case 1:
                LoadControl(new UCSelection(this));
                btnBack.Enabled = true;
                btnNext.Enabled = true;
                break;
            case 2:
                LoadControl(new UCConfirm(this));
                btnBack.Enabled = true;
                btnNext.Enabled = true;
                break;
            case 3:
                LoadControl(new UCProgress(this));
                btnBack.Enabled = true;
                btnNext.Enabled = true;
                break;
            default:
                break;
        }
    }
    
    private void LoadControl(BaseUserControl control)
    {
        control.Dock = DockStyle.Fill;
        pnlContent.Controls.Clear();
        pnlContent.Controls.Add(control);
    }

Your problem was in this line:

control = new BaseUserControl(this);

You were creating a new BaseUserControl... regardless of what you received by parameter. I guess that the BaseUserControl is in fact empty.
