I will be referring to the following example in my question: http://demos.telerik.com/kendo-ui/grid/editing
There are two validations: Product Name and Unit Price are both required.
When adding a new row, automatically the Product Name field shows a message that this field is required. If user supplies a product name and then moves on to add a new row, edit another row, etc., the Grid doesn't show a message that Unit Price is required, unless user clicks on the Unit Price cell.
Is there a way to prevent user from adding new rows or editing other rows, before filling in all required data for a row?
