Hi Al,

The built-in mechanism for satisfying this requirement, you can set the ValidatesOnDataErrors property of RadGridView to InViewMode. Note, that it can be used when the validation is performed through the IDataErrorInfo or INotifyDataErrorInfo interfaces. More information can be found in the Validating topic of RadGridView's online help.

As to modifying the background color of given cells depending on a property value, please, review the CellStyleSelector topic.

I hope you find this helpful.

Regards,
