Contoh menggunakan FlowLayoutPanel untuk menjabarkan kontrol yang terkandung satu demi satu. Ini juga mengatur dan AutoSizeMode untuk tumbuh dan menyusut AutoSize agar sesuai dengan konten bentuknya.

private void Form1_Load(object sender, EventArgs e)
{
    this.AutoSize = true;
    this.AutoSizeMode = AutoSizeMode.GrowAndShrink;
    this.Text = "URL Opener";

    flowPanel = new FlowLayoutPanel();
    flowPanel.AutoSize = true;
    flowPanel.AutoSizeMode = AutoSizeMode.GrowAndShrink;
    this.Controls.Add(flowPanel);

    urlLabel = new Label();
    urlLabel.Name = "urlLabel";
    urlLabel.Text = "URL:";
    urlLabel.Width = 50;
    urlLabel.TextAlign = ContentAlignment.MiddleCenter;
    flowPanel.Controls.Add(urlLabel);

    urlTextBox = new TextBox();
    urlTextBox.Name = "urlTextBox";
    urlTextBox.Width = 250;
    flowPanel.Controls.Add(urlTextBox);

    urlButton = new Button();
    urlButton.Name = "urlButton";
    urlButton.Text = "Open URL in Browser";
    urlButton.Click += new EventHandler(urlButton_Click);
    flowPanel.Controls.Add(urlButton);
}

void urlButton_Click(object sender, EventArgs e)
{
    try
    {
        Uri newUri = new Uri(urlTextBox.Text);
    }
    catch (UriFormatException uriEx)
    {
        MessageBox.Show("Sorry, your URL is malformed. Try again. Error: " + uriEx.Message);
        urlTextBox.ForeColor = Color.Red;
        return;
    }
    
    // Valid URI. Reset any previous error color, and launch the URL in the 
    // default browser.
    // NOTE: Depending on the user's settings, this method of starting the
    // browser may use an existing window in an existing Web browser process.
    // To get around this, start up a specific browser instance instead using one of
    // the overloads for Process.Start. You can examine the registry to find the
    // current default browser and launch that, or hard-code a specific browser.
    urlTextBox.ForeColor = Color.Black;
    Process.Start(urlTextBox.Text);
}

Keterangan

AutoSizeMode Mengatur properti ke nilai baru menyebabkan formulir ditata lagi.

Formulir tidak secara otomatis mengubah ukuran di perancang formulir Visual Studio, terlepas dari AutoSize nilai properti dan AutoSizeMode . Formulir mengubah ukuran dirinya dengan benar pada waktu proses sesuai dengan nilai kedua properti ini. Sebaliknya, kustom UserControl secara otomatis mengubah ukuran dirinya sendiri baik pada waktu desain maupun pada waktu proses.
