The BitmapEditor class provides a simple way to select a bitmap image for a property. Starting the editor displays an Open File dialog box that allows directory navigation and selecting a file. The file list is initially filtered for bitmap (.bmp) files.

The following code example uses an EditorAttribute to associate the BitmapEditor with a property.

[EditorAttribute(typeof(System.Drawing.Design.BitmapEditor), 
    typeof(System.Drawing.Design.UITypeEditor))]
public Bitmap testBitmap
{
    get
    {
        return testBmp;
    }
    set
    {
        testBmp = value;
    }
}
private Bitmap testBmp;
