[Solved] Visible = false and ReadOnly = True Column not available in ExtractValuseFromItem result

[ScalarSyS]

I have a N-tier application patterned after the Northwind N-tier example.

Page Codebehind:

**** this is where my problem is ("Object reference not set to an instance of an object")

        protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)
        {
            IDictionary dict = new Hashtable();
            GridEditFormItem editedItem = (GridEditFormItem)e.Item;
            editedItem.OwnerTableView.ExtractValuesFromItem(dict, editedItem);

            User editeduser = new User();

   ****        editeduser.Uid = int.Parse(dict["Uid"].ToString());
            editeduser.First = dict["First"].ToString();
            editeduser.Last = dict["Last"].ToString();
            editeduser.Username = dict["Username"].ToString();

            dataProvider.UpdateUser(editeduser);
        }

Since the column "Uid" is both hidden and read only it doesn't show up in "dict".

How can I work around this? What is the correct way to access the value of a hidden read only value from UpdateCommand event?

This is how I solved my issue...

        protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)
        {
            IDictionary dict = new Hashtable();
            GridEditFormItem editedItem = (GridEditFormItem)e.Item;
            editedItem.OwnerTableView.ExtractValuesFromItem(dict, editedItem);

            User editeduser = new User();

            editeduser.Uid = int.Parse(e.Item.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["Uid"].ToString());
            editeduser.First = dict["First"].ToString();
            editeduser.Last = dict["Last"].ToString();
            editeduser.Username = dict["Username"].ToString();

            dataProvider.UpdateUser(editeduser);
        }
