Web Forms :: Error Adding Item To List Box When Trying To Convert From VB.Net Code
Feb 24, 2010I inherited an application written for VB.Net and am converting it over to ASP.Net, with VB as the back end. I have a data pull that adds values to a new instance of a class, then adds the item to a listbox. It worked great in the VB.Net version, but I get the following error in the Visual Studio Text Editor when I try to use the code:
Overload resolution failed because no accessible 'Add' can be called with these arguments:
'Public Sub Add(Item As System.Web.UI.WebControls.ListItem)':Value of type 'MyItem' cannot be converted to System.Web.UI.WebControls.ListItem'.
'Public Sub Add(Item as String)':Value of type 'MyItem' cannot be converted to String.

DataSource Controls :: Loading Datatable From SQLDataReader Does Not Call Set Method?
Apr 28, 2010When using the DataTable.Load(SQLDataReader) method, if the datatable is a property of a class, the set method is not called to populate the object. For example...
MySQLDataReader = command.ExecuteReader();
if (MySQLDataReader.HasRows)
myObjDataTable.Load(MySQLDataReader); -- The result of this will be 0 rows returned. The "Set" method of the object is never called.
