'Telerik.Web.UI.GridColumnValidationSettings' does not have a public property named 'ModelErrorMessage'

My system works  well before I upgrade Telerik Web UI dll to 2013.3.1324.0 ,   after I upgrade, I find the I cannot build the system, and got  following error.

'Telerik.Web.UI.GridColumnValidationSettings' does not have a public property named 'ModelErrorMessage'

We do add the property in many pages. but it is ok in previous version.

Can u give us a clue how to solve that?

Thanks
