I have attached a simple project that demonstrates the issue i am having. I want a user to be able to filter using the contains function by any columns with an enter key press (I have already done this thanks to a previous support ticket, thank you telerik support). However, now my issue is that i want the user to be able to filter using the equal to function on the enter key press for date columns which i have also been able to figure out how to do. My only issue is that when the user types in letters or an invalid date, the filter comes back with an invalid date error. I need it to validate the date before it filters the column so there cannot be an error. I noticed that if i type in an invalid date then actually go in and click equal to filter function then it will not filter until i have changed the date to a valid date and clicked the filter function again. I would like to achieve this same functionality but using the enter key press. Thank you.

Here is my source code:
