VS.NET does not provide the facilities to create an animation bar..or animated lables..
If you want to create animation buttons or lables you gotta use an external software like Adobe Photoshop,Image Viewer,etc..
The animation image is usually in .GIF format..
Workaround:
1.What I do for my application for simple color change for buttons or lables..I kinda use two images and Swap the image when the user points his mouse at the buttons..
2.You gotta do that in Javascript and each webcontrol has it own properties .. Onmouse over help you to get a different image when the user points the Mouse over the button or the lable..
3.Other way of doing this is by using a timer and swap the images after particular time intervals..(I generally dont advise this)
