Change color of one cell in the DataGrid control ( C#)
http://datawebcontrols.com/faqs/CustomizingAppearance/ConditionalFormatting.shtml
The DataGrid provides a plethora of properties that can be set to specify the DataGrid's formatting. For example, you can have each consecutive row of a DataGrid alternate between two different colors merely by setting the DataGrid's AlternatingItemStyle's BackColor property.
While the AlternatingItemStyle is a great way to apply different formatting for every other DataGrid row, oftentimes developers want to perform conditional formatting based on the value(s) of a DataGrid row. For example, imagine a DataGrid that displays a list of products, including the product's name and price. Perhaps you want to draw the user's attention to products that are at "bargain-basement" prices. Namely, if a product has a price less than, say, $10.00, you want to have that row highlighted.
This can be accomplished by providing an event handler for the DataGrid's ItemDataBound event. The ItemDataBound fires once for each DataGridItem added to the DataGrid (that is, it fires once for each row that is added to the DataGrid). Essentially, what we need to do is in this event handler, check to see if the price is below the threshold ($10.00, or whatever lower bound you choose). If it is, then we want to set the DataGridItem's BackColor property to Yellow, thereby highlighting the row.
