Additional parameter to WCF Service Update method

[Bogdan Cucosel]

Hello,

I know that when setting the Select method of the Grid, additional parameters can be sent to the WCF Service method by hooking to the DataBinding event.

Can I do the same for Update and Delete methods ?

I tried doing in th OnSave event the same thing as in the OnDataBinding event , but did not work.

Any help is greatly appreciated .

Thank you,
Bogdan

Hello Bogdan,

When you use the Save event of the Grid you can send the values like this:

function onGridSave(e){
    e.values.foo = "test 1";
    e.values.bar = 23;
}

Hello Petur,

Yes , but that way , the entity that should be saved , must have those properties.

I would like to have clean POCO classes in my model, and not polute them with properties needed for infrastructure.

I tried somethng like 

function onSave(e) {
    var y = { Entity: e.values, myProperty: "ggg" };
    e.values = y;
}

but this did not solve my problem, because it still sends to the server the edited entity.

The related code on the server side looks like :

public class CrudQueryParameter<T>
{
    public string myProperty { get; set; }

    public T Entity { get; set; }
}


    [OperationContract]
    public GridModel Update(GridState state, CrudQueryParameter<TEntity> value)
    {
        commandService.Execute(new SaveOrUpdateCommand<object> { Entity = value.Entity });

        return null;// gridQueryService.ExecuteGridQuery(definition, state);
    }

Do you think something like this could be accomplished in any way ?

Thank you,
Bogdan

Hello again Bogdan,

You do not need to extend your model with such properties. If you send value like this:

function onSave(e){
    e.values.foo = 123;
}

On the server you could append additional argument to the method signature and it will be populated successfully.

public ActionResult Update(string foo, ...)

Kind regards,

Hello Petur,

There must be something wrong. When I do what you say , this is what Fiddler is telling me it is being sent to the client :

<P>{"value":{"Id":"1","Description":"GIBRALTARr","myParameter":"ggg"},"state":{"page":"1","size":"10","groupBy":"","filter":"","orderBy":"","aggregates":""}}</P>

You can see that myParameter is neing sent as a property of value, this is way I was talking about extending the entity.

Is there something I am missing ?
Thank you,
Bogdan
