DataMemberAttribute in Contract class

Posted on by Community Member

Hi all,

Usually when we create a Data Contract class when creating a SSRS report, we put something like this for the parameter :

[ DataMemberAttribute("Firstname"),

SysOperationLabelAttribute(literalStr("@SYS32695")),

SysOperationDisplayOrderAttribute('2')

]

public Name parmFirstname(Name _firstName = firstName)

{

firstName = _firstName;

return firstName;

}

My question, can we put a default value in the box ? so when I run this report, and UI some of the field already has default value.

Thanks

Hi Wwwong,

First, I agree to use SysOperationInitializable.

In addition, I would like to ask if you have a controller class?

You can override method prePromptModifyContract in controller class, then add code to set your default value.

You can either implement SysOperationInitializable or assign a value during variable declaration, here is an example https://erconsult.eu/blog/extending-sysoperation-contracts-with-datamemberattribute/

RE: DataMemberAttribute in Contract class

Hi WWwong,

There are a couple of interfaces that can bring additional "features" to contract classes. One of them is SysOperationInitializable, which allows you to initialize variables with default values. You just need to indicate that your contract implements a certain interface with "implements" keyword and implement interface methods in your contract.
