Closed Then OpenConnection2( ) With Cmd .Connection = cnn2 .CommandType = CommandType. Text .CommandText = sql End With Ad = New SqlDataAdapter( Cmd) Ad.Fill(ds, "tmp") Lst.DataTextField = TextField If ValueFld <> "" Then Lst.DataValueField = ValueFld End If Lst.DataSource = ds Lst.DataBind( ) Catch ex As Exception Current.Response. Write(ex. Message) Finally ds.Dispose() Ad.Dispose() Cmd.Dispose( ) 'cnn2.Close( ) End Try End Sub ------------ --------- --------- --------- --------- --------- - and Then i replaced function with Object ------------ --------- --------- --------- --------- --------- - Public Sub BindListControl( ByVal Lst As Object, ByVal sql As String, ByVal TextField As String, Optional ByVal ValueFld As String = "") Dim ds As New DataSet Dim Ad As New SqlDataAdapter Dim Cmd As New SqlCommand Try If cnn2.State = ConnectionState.

ToString( )); } finally { con.Close(); adapater.Dispose( ); cmd.Dispose( ); } } else { Response.Write( "Connection Not Available"); } } -------------------------------------- It will work with ListBox control ----------------------------------- if i replace ListBox with Object it will through Error that object does not contain defination for DataTextField, DataSource, DataBind( ) so sir it will work in vb.net why not in c# is any alternate way to do this or any other syntax please send me response as earily as possible Thank u sir		View Answer
