ObjectdataSource Inserting event not firing up ?

Question

Hi I have an objectDataSource and i am trying to pass an object as parameter in its Inserting event. For some reason the "Inserting" is not getting fired up before Insert is called.

It is not getting into

ObjectDataSource1_Inserting(object sender, ObjectDataSourceMethodEventArgs e)

Event block for some reason. Any idea ?

Here is the ObjectDataSource and the code where its Insert method is been called.

here is the object i need to pass

  public class FeedItem
    {
        string feedItemTitle;
        string feedItemLink;

        public string FeedItemTitle
        {
            get { return feedItemTitle; }
        }
        public string FeeDItemLink
        {
            get { return feedItemLink; }            
        }

        public FeedItem(string _feedItemTitle, string _feedItemLink)
        {
            feedItemTitle = _feedItemTitle;
            feedItemLink = _feedItemLink;
        }
    }

Thanks

To pass user-defined objects to a ObjectDataSource you must including a default constructor that takes no parameters. The data source object's public properties must also expose both get and set accessors.

 public class FeedItem
 {
    string feedItemTitle;
    string feedItemLink;

    public string FeedItemTitle
    {
        get { return feedItemTitle; }
        set { feedItemTitle= value; }
    }

    public string FeeDItemLink
    {
        get { return feedItemLink; }
        set { feedItemLink= value; }            
    }

    public FeedItem(){}

    public FeedItem(string _feedItemTitle, string _feedItemLink)
    {
        feedItemTitle = _feedItemTitle;
        feedItemLink = _feedItemLink;
    }
 }

Once i encountered the same issue but solution was very simple, one of our developer has subscribed the event in if (Page.PostBack == false)

So as per the fundamentals (http protocol) server will forget binding on next post back
