How to use request states for multiple items at the same time?

Hi Community, maybe somebody has faced a similar task before and can give me some hints. I have an relationship onAfterDelete server Method that is triggered when an relationship item is deleted....

    Hi Angela, 

    my previous post was marked as spam for some reason, so I will try again:

    You can have any object as your value for a key in RequestState. So in your onBeforeDelete method you could include something like this:

    if (RequestState.Contains("prevRelID")) {

    List<string> relIdList = (List<string>)RequestState["prevRelID"];

    relIdList.Add(this.getProperty("related_id", ""));

    } else {

    RequestState.Add("prevRelID", new List<string> { this.getProperty("related_id", "") });

    }

    So on your onAfterDelete method, you can now access this list of related IDs with something like

    List<string> relIdList = (List<string>)RequestState["prevRelID"];

     

    Hope this helps some.

    Cheers,

    C

Hi Angela,

I haven't worked with RequestState all that much, but looking at it in Aras.Server.Core and playing around with it, it looks like you can add any type of object as the keyed value, including, for example, a List of strings. Not saying this is best, but what you could do is something like this in the onBeforeDelete method

if (RequestState.Contains("prevRelID")) {
    List<string> requestList = (List<string>)RequestState["prevRelID"];
    requestList.Add(this.getProperty("related_id", ""));
} else {
    RequestState.Add("prevRelID", new List<string> { this.getProperty("related_id", "") });
}

And then simply go through that list in the onAfterDelete method. Would something like that work for you?

Cheers,

C
