    Hi All,

    I am trying to itrate DISCUSSION BOARD items(threads),
    and List.ItemCount shows 2 items, but when i try to access
    items, it shows listItem null, and debugger comes out of loop

         SPList list=web.Lists["DBoard"];
                int i = list.ItemCount;
                foreach (SPListItem listItem in list.Items)
                {


                }

    I am not able to find, what i am doing wrong here.

    Arun, you can try the below code

    SPList list = myweb.Lists["DBoard"];
            SPQuery myquery = new SPQuery();
            myquery.Query = "<Query><OrderBy><FieldRef Name='Subject'/></OrderBy></Query>";
            SPListItemCollection myitemcol = list.GetItems(myquery);
            DropDownList1.Items.Clear();
            DropDownList1.AppendDataBoundItems = true;
            DropDownList1.Items.Add(new ListItem("Select...", ""));
            foreach (SPListItem listitem in myitemcol)
            {
                DropDownList1.Items.Add(new ListItem(listitem["Subject"].ToString()));
            }

    Hi RAJ,

    Actually i am using SPEmailEventReciever handler, inside that i placed ur code...

    But as usual it is coming from loop 

    foreach     (SPListItem listitem in myitemcol)
                {
                    DropDownList1.Items.Add(new ListItem(listitem["Subject"].ToString()));
                }

    as it is not getting item in the collection.
    I dont know what is happening here.
