    When I click "add new row", required field validation raises exceptions/constraints one cell at a time. i.e. not allowing the rows data to be entered in any other order / or for the entire row to appear in edit mode.

    behavior reproducible on BatchEditing demo page: http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

    It seems like I would have noticed this before, so maybe it's update related: I have a RadGrid that has Batch Edit row mode enabled.

    Is that intended? Can it be changed with an attribute? if not, how about some client side js? I'll be debugging, but would appreciate an available solution.

    Found "solution" by JavaScript debugging. combination of js errors from GridTemplateColumn:DefaultInsertValue not yet being options in dropdown lists(unhandled js exceptions on adding row in Telerik.Web.UI.WebResource.axd) and ColumnValidationSettings attr: RenderValidatorBeforeEditor="false".

    The solution you found is proper one and can be used in your scenario.
    Also I am attaching a simple example demonstrating such client-side validation, where you could go through each row, get reference to any of the cells of that row and validate each value. This should be achieved in the client-side OnCommand event of the grid. If the validation fails for any row you could cancel the command, which will prevent the postback.
