Create New Feature, Populate a field based of ObjectID value

[NathalieNeagle]

I have an applicaiton Silverlight and when a users creates a new feature, I want to automatically populate a field called "FeatureID" with the value that was assigned in the ObjectID field (by ArcGIS).  I'm struggling with how to do this and I'm wondering if someone could give me a push or insight. 

I would love to do it on the back-end in the database schema (like how you do it for a domain and you have a default domain in your GDB but I don't think this is possilble so I'm looking to do it in code).



Thanks
Nathalie

Did you try to subscribe to Editor.EditCompleted event and in the Handler, test if action is 'Add' and update your attribute there?

Dom,

Thanks for the reply.  I fell off this task for awhile but now I'm back on and need to finish up.  After I listen for the Editor.EditCompleted event I then need to update the features attribute.

I was looking for answer on the rest api page.  Before I check this post I posted a question about the work-flow

http://forums.arcgis.com/threads/89806-My-own-attribute-editing-function

Here it is so you don't have to link over

I've been looking at the Apply Edits (Operation) example in the help document (REST API).

I can take an example there and add a feature and update a feature -

http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/

I can add and update for the html. I do this by going to the end point

http://sampleserver3.arcgisonline.co...r/0/applyEdits

and dropping the appropriate code in the entry areas.

If I switch to JSON I can also get the JSON to work


Here's where I'm no stuck

How do I push an update from my code. Do you write everything in the url string
EXAMPLE - http://sampleserver3.arcgisonline.co...Edits/****HTML OR JSON **TO DO WORK***

Or do you somehow give the url in your code
http://sampleserver3.arcgisonline.co...r/0/applyEdits
and then place your html or JSON in the appropriate input boxes -- "ADD, UPDATES, DELETES"

Will you show me an example of this - I'm writing in Silverlight but if the example was in JS or FLEX I'm sure I could figure it out.

I would like to push with JSON

An example would be great to show me, I should be able to study that example and learn from that and do it on my own.



Right now I have this:

void EditorWidget_EditCompleted(object sender, Editor.EditEventArgs e)
  {
    if (e.Action == Editor.EditAction.Add)
    {
    foreach (var edit in e.Edits)
     {
       if (edit.Layer is FeatureLayer)
        {
         if (e.Action == Editor.EditAction.Add)
          {
             .....udate feature layer with JSON update here
           }
         }
     }
    }
}


Not totally sure if that is correct but....

THanks
Nathallie.
