Using listview datakeyname for listbox parameter

[jrobbins]

I have managed to put a listbox in my listview and have gotten the box to appear but it is empty. I want to click on the Edit link and based on the datakeyname value pass the parameter to the objectdatasourc e to fill the listbox. I'm trying to use IEnumerable and am not getting it. Can someone help with an understandable example. Or another way to do it.

I'm at a loss to what I am to return (see ??? ) and it doesn't like my (SqlInt32 PersonnelNumber ) telling me it can't convert to "SqlInt32? (in my EmployeeObject) " -

public IEnumerable<AuthorizationObjectClass> GetEmployeeNoAuthorizations(SqlInt32 PersonnelNumber)
        {
            DataSet ds;
            AuthorizationObjectClass auth = new AuthorizationObjectClass();
            try
            {
                //EmployeeObjectClass Emp = new EmployeeObjectClass();
                Emp.PersonnelNumber = PersonnelNumber;
                ds = data.GetNotSelectedAuthorizations(Emp);
                if (ds.Tables.Count > 0)
                {
                    auth.AuthorizationID = Convert.ToInt32(ds.Tables[0].Rows[0]["AuthorizationID"]);
                    auth.AuthorizationDefinition = Convert.ToString(ds.Tables[0].Rows[0]["AuthorizationDescription"]);
                }
            }
            catch (Exception e)
            {
                Console.WriteLine("{0} Exception caught.", e);
            }
            return  ???? ;
        }

and it doesn't like my (SqlInt32 PersonnelNumber ) telling me it can't convert to "SqlInt32? (in my EmployeeObject) "

I'm guessing the SqlInt32 is a single item from within the Employee object..

If your return type is the SqlInt32, don't try to return the entire employee object: return just the ID number .... return myEmployeeObjec t.PersonnelNumb er;

If you want to return the entire EmployeeObject, then change your return type from a SqlInt32 to an EmployeeObject type.... return myEmployeeObjec t;

obtained id value can't bind to datatable to listbox

[QUOTE]I was able to retrieve my id field; but when I try to bind results to listbox (NOAUTH), my listbox is showing as null and won't allow the binding. Any ideas?

QUOTE]

  protected void lvSearchResults_ItemEditing(Object sender, ListViewEditEventArgs e)
    {

        string id = lvSearchResults.DataKeys[e.NewEditIndex].Value.ToString();
        
        ListViewItem item = lvSearchResults.Items[e.NewEditIndex];
       CoreDataManager lbNoAuth = new CoreDataManager();

        DataTable dt = lbNoAuth.GetNotSelectedAuthorizations(id);

        ListBox NoAuth = (ListBox)item.FindControl("lbNoAuthorizations");

        
        if (dt.Rows.Count > 0)
        {
                     
            NoAuth.DataSource = dt;
            NoAuth.DataTextField = dt.Columns[1].ColumnName;
            NoAuth.DataValueField = dt.Columns[0].ColumnName;

I don't do a lot of this stuff, but...

        
ListBox NoAuth = (ListBox)item.FindControl("lbNoAuthorizations");

If the result of your FindControl is null (no matching controls found) then NoAuth would be null.

passing datakey to objectsource to populate listbox inside a listview

I finally figured this after lots of searching. I have a listbox inside my listview. I grab the datakey on the OnItemEditing event in the listview and then pass the objectdatasourc e the datakey as the default parameter.

protected void lvSearchResults_OnItemEditing(object sender, ListViewEditEventArgs e)
    {
            ListViewItem currentItem = lvSearchResults.Items[e.NewEditIndex];
        
            string id = lvSearchResults.DataKeys[e.NewEditIndex].Value.ToString();
            Response.Write("datakey:  " + id);
            odsNotSelectedAuthorizations.SelectParameters["PersonnelNumber"].DefaultValue = id;
            odsSelectedAuthorizations.SelectParameters["PersonnelNumber"].DefaultValue = id;
    }
