Initialize,Validate methods in contract class in ax 2012 using X++

 Hi guys,Today we see how to add Initialize,Validate methods in contract class in ax 2012 by X++.

In data contract class we have to use SysOperationAlwaysInitializeAttribute.

For Initialize we have to use SysOperationInitializable class.

For Validate we have to use SysOperationValidatable class.

The above 2 methods we have to add in data Contract Class By Implements Key Word.

Check Below code for better UnderStanding.

DataContract Class:

[DataContractAttribute,SysOperationAlwaysInitializeAttribute]

class SysOperationDemoDataContract implements SysOperationInitializable,SysOperationValidatable

{

    Name            name;

    BirthDate       birthDate;

}

Initialize method:

public void initialize()

{

    name='';

    birthDate= dateNull();

}

validate method:

public boolean validate()

{

    if (this.parmName('') )

    {

       return checkFailed('Enter Name Value');

    }

    return true;

}

Keep Daxing !!
