An image list is a collection of images of the same size, each of which can be referred to by its index. Image lists are used to efficiently manage large sets of icons or bitmaps. All images in an image list are contained in a single, wide bitmap in screen device format. An image list can also include a monochrome bitmap that contains masks that are used to draw images transparently (icon style).
I have some images that i added to imageList Cotrol manually. Now i need remove thart images from imageList depending on the key index and set as panel backgroud.
An ImageList is a supporting control that is typically used by other controls, such as a ListView but is exposed as a component to developers. We can use this component in our applications when we are building our own controls such as a photo gallery or an image rotator control.
