Good afternoon Bob
There are several methods to create a horizontal gradient background for a
client-side table cell:
**** METHOD 1. Use CSS ****
If you're fine with restricting to IE then we can create gradients using
CSS filters (the Microsoft homepage did this for a long while): see
http://msdn.microsoft.com/en-us/libr...97(vs.85).aspx.
This only works for IE. It cannot be rendered by Firefox, Safari, etc.
However, some community members enhanced this solution by adding the
cross-browser support:

This has been tested and verified to work in MSIE6, Firefox 1.0.7, Safari
2.0.1, Opera 7.5 & 8.5 on Windows 2K, XP and OS X.

Strength: We can dynamically define the gradient color range.
Weakness: The performance is relatively lower than METHOD 2
**** METHOD 2. Stretch a static image to fill the table cell ****
If you know what the start and end colors are in advance, we can pre-design
an image with the expected gradient color range, then load and stretch the
static image to the table cell.
Strength: Better performance.
Weakness: The background image need to be pre-designed, so we cannot
dynamically change the color range of the gradient effect.
By the way, some people may suggest using GDI+ to programmaticall y create
such an image in method 2 so that we can dynamically change the start color
and the end color. For example:

Please note that this is not an supported behavior. GDI+ is not supported
to be used in ASP.NET, ASP, or windows service. This may lead to some
unexpected results.
