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?
