Is this what you need - https://docs.telerik.com/devtools/wpf/controls/radgridview/styles-and-templates/styling-a-row
If you want to style conditionally, you can look here - https://docs.telerik.com/devtools/wpf/controls/radgridview/style-selectors/rowstyleselector
Something like this should do what you are after. You might want to use a behaviour and Style Selector so it is more reusable (and esp if you are using MVVM) but this should get you in the right direction using code behind. There is a simple Task.Wait to simulate your Telemetry response delay in the code behind.
Below is a full working example, unfortunately, I can't upload a zip of it, so I will paste without line numbers and label each file.
You can use implicit style Targeting GridViewRow or RowStyleSelector as suggested Maurice in his first reply. In MVVM scenario you can create implicit style and bind the Background/Foreground property to a property from your model with the desired color.
The sample project attached to this reply, demonstrate this approach.
P.S. I have removed the duplicate email.
