Hello, I'm having a problem where validation is not firing for columns utilizing ColumnValidationSettings when they are within detail tables within hierarchical radgrids. I am just using required field validators, but when a user edits or inserts in the insert/edit modal and does not fill them in the validation does not fire. The same validation settings work just fine at the mastertableview level in the same grid, just not at deeper tiers within the hierarchy.

The relavant columns have data fields 'Start_Date' and 'End_Date'.

Here is my source (with datakeys, columns etc renamed):
