Hi. I have grid with my pop up editor template.
How Can I add some validation before I save changes?
For example I start edit\create row. When I press button Update in pop up window I want check database and compare entered data. And If user enter wrong data I want show message and didn't close window until user enter correct data or press button Cancel.
