Parameters

left
The left edge of the inner rectangle of the gradient, ranging from 0.0 (the left of the cell) to 1.0 (the right of the cell).
top
The top edge of the inner rectangle of the gradient, ranging from 0.0 (the top of the cell) to 1.0 (the bottom of the cell).
right
The right edge of the inner rectangle of the gradient, ranging from 0.0 (the left of the cell) to 1.0 (the right of the cell).
bottom
The bottom edge of the inner rectangle of the gradient, ranging from 0.0 (the top of the cell) to 1.0 (the bottom of the cell).
color1
The color at the inner rectangle of the gradient.
color2
The color at the outer rectangle (cell edges) of the gradient.
Exceptions
ExceptionDescription
System.ArgumentOutOfRangeExceptionleft, top, right, or bottom are less than 0.0 or greater than 1.0.
System.ArgumentExceptioncolor1 or color2 are empty or system colors or have a non-opaque alpha channel.
Remarks

The rectangular gradient is defined by specifying an inner rectangle and a set of gradient stops. The gradient goes from the edges of the inner rectangle to the edges of the cell. If the inner rectangle does not have a height or width of 0, the color of the first gradient stop will be filled in the center of the inner rectangle.

The inner rectangle is defined by the left, top, right, and bottom parameters. They are relative values ranging from 0.0 to 1.0 and they go from the top/left to the bottom/right. So, for example, to specify a gradient that goes out from the center, all values would be 0.5. Or to specify a gradient which goes out from the bottom-left corner of the cell, the following values would be used: left = 0.0, top = 1.0, right = 0.0, bottom = 1.0.
