ListBox with Icons

Listbox Control with an image property for every item


All of us like more color or image in our control, so do I.

In this article, I give each item in the custom ListBox class an image property.

Note: my article has no source code because it very short and easy.

First: we create 2 classes for GListBox

// GListBoxItem class 
public class GListBoxItem
    private string _myText;
    private int _myImageIndex;
    // properties 
    public string Text
        get {return _myText;}
        set {_myText = value;}
    public int ImageIndex
        get {return _myImageIndex;}
        set {_myImageIndex = value;}
    public GListBoxItem(string text, int index)
        _myText = text;
        _myImageIndex = index;
    public GListBoxItem(string text): this(text,-1){}
    public GListBoxItem(): this(""){}
    public override string ToString()
        return _myText;
}//End of GListBoxItem class

// GListBox class 
public class GListBox : ListBox
    private ImageList _myImageList;
    public ImageList ImageList
        get {return _myImageList;}
        set {_myImageList = value;}
    public GListBox()
        // Set owner draw mode
        this.DrawMode = DrawMode.OwnerDrawFixed;
    protected override void OnDrawItem(System.Windows.Forms.DrawItemEventArgs e)
        GListBoxItem item;
        Rectangle bounds = e.Bounds;
        Size imageSize = _myImageList.ImageSize;
            item = (GListBoxItem) Items[e.Index];
            if (item.ImageIndex != -1)
                imageList.Draw(e.Graphics, bounds.Left,bounds.Top,item.ImageIndex); 
                e.Graphics.DrawString(item.Text, e.Font, new SolidBrush(e.ForeColor), 
                    bounds.Left+imageSize.Width, bounds.Top);
                e.Graphics.DrawString(item.Text, e.Font,new SolidBrush(e.ForeColor),
                    bounds.Left, bounds.Top);
            if (e.Index != -1)
                    new SolidBrush(e.ForeColor) ,bounds.Left, bounds.Top);
                e.Graphics.DrawString(Text,e.Font,new SolidBrush(e.ForeColor),
                    bounds.Left, bounds.Top);
}//End of GListBox class

After that, in order to use our code, we could do:

GListBox lb = new GListBox();
lb.ImageList = imageList;
lb.Items.Add( new GListBoxItem("Image 1",0));
lb.Items.Add( new GListBoxItem("Image 2",1));
lb.Items.Add( new GListBoxItem("Image 3",2));

That's all and thanks for reading.
