If condition on a checkbox

Hello everybody,

     I would like to know how do you check the value of a checkbox (isDone__c), whether it is true or false.
     I have tried this: if(isDone__c)  and I am getting the following error: Condition expression must be of type Boolean.


Thanks for any help,
Vijay,

Hi,
Is this a property in apex or a field in an object?

Hi!

     The filed in found in Work object, therefore (work.isDone__c).
     Even then, I have the same error.

Regards,
Vijay

you should not give your object name it should be your variable name of your object instance (record)

Hi Vijay,

Confirm one time whether the field is checkbox and do a system.debug for work.isDone__c atlast you can try like this if(work.isDone__c == true)

I have tried the code 

If(work.isDone__c == True){
...
}

But I get the error: Comparison arguments must be compatible types: Schema.SObjectField, Boolean

Hi Vijay ,

What is the type of isDone__c ?

isDone__c is a checkbox.

And, is it possible to store the value of the checkbox in a variable?

Hi Vijay,

You might have forgotten to mention the trigger context.
work workcheck = Trigger.new[0]; // if you want to check on the first record
then if(workcheck.isDone__c) will work.

In case you forget to do this, you have to explicitly change the field type to boolean
eg : Boolean isChecked=work.isDone__c;
