WPF RadGridView Style a cell depending on another cell in the same row dynamically.

[Dean]

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.

This is the xaml code for the gridview.

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.
