    Hi Buddy,

    What a brilliant post I have come across and believe me I have been searching out for this similar kind of post for past a week and hardly came across this.

    I have started using ag-grid in my the Angular 4 project and was unable to find any API's for performing in-line cell validations i.e. whenever the user edits a particular cell, the requirement is to perform a required field and pattern validation. In case of any validation errors, the corresponding editable field should get highlighted and an error message needs to be displayed.
    I have used the following cell events to fulfill the above purpose, but none of them provided me the desired result.
    • cellEditingStarted
    • cellEditingStopped

    I look forward to see your next updates.

    MuchasGracias,

    According to many websites, Scala is faster than Java. Some programmers even claim that Scala is 20% faster than Java. Both these programming languages run on JVM. ... Also, the Scala developers have option to use several Java development libraries and frameworks as it is also a JVM language..keep it up!!
