OnValidatedField table event handler method in Dynamics 365 F&O

Event handlers can be use to fire up your code without the necessary to customize and interfere on core logic and elements.

On the example below i’ll create an event handler that will validate FirstName value of DirPersonName table.

Open DirPersonName table and on tab Events find onValidatedField, copy and Event handler and paste in class you have created before.

Example:

class DirPersonNameTable_EventHandler
{
       /// <summary>
    ///
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    [DataEventHandler(tableStr(DirPersonName), DataEventType::ValidatedField)]
    public static void DirPersonName_onValidatedField(Common sender, DataEventArgs e)
    {
        DirPersonName dirPersonName = sender as DirPersonName;
        ValidateFieldEventArgs validateFieldEventArgs = e as ValidateFieldEventArgs;
        boolean ret = validateFieldEventArgs.parmValidateResult();
        ;

        if(ret)
        {
            switch(validateFieldEventArgs.parmFieldId())
            {
                case fieldNum(DirPersonName,FirstName):
            if(DirPersonName.FirstName != "MicrosoftDynamics365FO")
                    {
                        ret = checkFailed("Name must be MicrosoftDynamics365FO");
                    }
                    break;

                default:
                    break;
            }
        }
    }

}

Save the class and build the project.
