Hi Gopal,
There are two posibilities that, your Table row/cell coloring is not working
1:
Make sure that you have bound the columns "CellDesign" property to COLOR attribute as below
Note: If you need to color whole ROW, then you need to bind the cellDesign of all columns to COLOR, otherwise, only respective cells gets colored.
2. Make sure that the property "Design" of table should not be set to "ALTERNATING", because it overrides the color. Hence, set the design of table to "standard"
Hope this resolves your issue.
Regards,
Rama
