How to add a button to an item Listbox?

Hi,

If you are using winform it will be a bit tricky. Here is a simple way to do it.
you need to draw a fake button in the DrawItem event and the click event.

private void InitializeListBox()
{
    listBox1.Items.AddRange(new Object[] { "item 1", "item 2", "item 3", "item 4", "item 5", "item 6", "item 7", "item 8", "item 9" });
    listBox1.DrawMode = DrawMode.OwnerDrawFixed;
    listBox1.DrawItem += new DrawItemEventHandler(ListBox1_DrawItem);
    listBox1.ItemHeight = 25;
}

private void ListBox1_DrawItem(object sender,
    System.Windows.Forms.DrawItemEventArgs e)
{
    // draw a fake button, add some padding, and put a label.
    var bounds = e.Bounds;
    var buttonBounds = new Rectangle(bounds.X +2 , bounds.Y + 2, bounds.Width - 4, bounds.Height - 4);
    ControlPaint.DrawButton(e.Graphics, buttonBounds, ButtonState.Normal);
    _font = e.Font;

    var textBounds = new Rectangle(buttonBounds.X + 2, buttonBounds.Y + 2, buttonBounds.Width - 4, buttonBounds.Height - 4);
    e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), _font, Brushes.Black, textBounds, StringFormat.GenericDefault);
}

private Font _font;

private void listBox1_MouseClick(object sender, MouseEventArgs e)
{
    // draw a button pushed, wait a bit draw a button up.
    int index = this.listBox1.IndexFromPoint(e.Location);
    Rectangle bounds = this.listBox1.GetItemRectangle(index);

    var buttonBounds = new Rectangle(bounds.X + 2, bounds.Y + 2, bounds.Width - 4, bounds.Height - 4);
    ControlPaint.DrawButton(Graphics.FromHwnd(this.listBox1.Handle), buttonBounds, ButtonState.Pushed);

    var textBounds = new Rectangle(buttonBounds.X + 2, buttonBounds.Y + 2, buttonBounds.Width - 4, buttonBounds.Height - 4);
    Graphics.FromHwnd(this.listBox1.Handle).DrawString(listBox1.Items[index].ToString(),_font, Brushes.Black, textBounds, StringFormat.GenericDefault);

    Thread.Sleep(100);

    ControlPaint.DrawButton(Graphics.FromHwnd(this.listBox1.Handle), buttonBounds, ButtonState.Normal);
    Graphics.FromHwnd(this.listBox1.Handle).DrawString(listBox1.Items[index].ToString(), _font, Brushes.Black, textBounds, StringFormat.GenericDefault);

    // do what ever you want.
    if (index != System.Windows.Forms.ListBox.NoMatches)
    {
        MessageBox.Show(index.ToString());
    }
}

This code is a bit rough, you will need to polish it, but it gives you an idea.

Hope it helps.

Valery.
