The item source of this gridview is bound to a DataTable programmatically. The amount of columns change depending on how many days the user wants to see. I need all of the Date cells to have a foreground (Text colour) of red if they do not equal the number in the expected column.

I have tried many ways of accomplishing this but nothing seems to work.

Thank you in advance.

ItemContainerStyle="{StaticResource MenuItemContainerStyle1}"
telerik:StyleManager.Theme="Windows8" ItemClick="GridContextMenu_ItemClick"

Hello Dean,

Thank you for the provided image and code snippet.

Based on them I prepared a small sample project which I believe achieves your requirement. For the purpose, I've used the CellStyleSelector property of the columns and in the SelectStyle method, I compare the value of the current cell with the one from the Expected column.

Please have a look at the attached project and let me know if it provides the desired result.
