Hello @Shweta

Please check the below Code:
  
trigger TaskTrigger on Task (after update) {
	for(Task newTask : Trigger.New){
		// Task.WhoId != null                      ----Checks Contact is null or not
		// ((string)Task.WhoId).startsWith('003')  ----Checks Task is related to Contact
		// Task.WhatId == null                     ----Checks the related to field is null or not
		if(Task.WhoId != null && ((string)Task.WhoId).startsWith('003') && Task.WhatId == null ){
			// Add your code as per your needs.
		}
	}
}

HI Jolly,

Thank you for your reply. I do need to pre-fill the value before submitting the record. I meant need to do on before insert.

Thanks, Shweta

Shweta,

For this you check the below code, the changes you will made in the newTask it will automatically update the tasks values.
  
trigger TaskTrigger on Task (before insert) {
	for(Task newTask : Trigger.New){
		// Task.WhoId != null                      ----Checks Contact is null or not
		// ((string)Task.WhoId).startsWith('003')  ----Checks Task is related to Contact</b>
		// Task.WhatId == null                     ----Checks the related to field is null or not
		if(Task.WhoId != null && ((string)Task.WhoId).startsWith('003') && Task.WhatId == null ){
			// Add your code as per your needs
		}
	}
}
