This is the source for the approve record record action

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Umbraco.Forms.Core.Services;

namespace Umbraco.Forms.Core.Providers.RecordActions
{
    public class ApproveRecord : RecordActionType
    {
        public ApproveRecord()
        {
            this.Description = "Approves a record";
            this.Icon = "approve.png";
            this.Id = new Guid("cb126b72-9011-11df-a4ee-0800200c9a66");
            this.Name = "Approve";
        }

        public override Enums.RecordActionStatus Execute(Record record, Form form)
        {
            RecordService s = new RecordService(record);

            if (s != null)
                s.Approve();

            s.Dispose();

            return Enums.RecordActionStatus.Completed;
        }
    }
}

And to change the state back to submitted  rs.Record.State = FormState.Submitted

Would it be possible to use your own states, like for example "Rejected", "Delivered" etc.?

If you want to execute workflows on states you can't use custom ones only the default ones

But if it's just to store a custom state you can add a hidden field and then set the value of that to your custom state...

Ok, so if I use a hidden field called "active" and want to change the value from "1" to "0". Could I then use the same code for that?

Hello again Tim.

Would it be possible to call an record action from front end?

//Kalle

Well record actions are for extending the records viewer if you don't want to extend that and just execute some code you don't need the record action...

is working on a reply...
