I'm new in ASP. Can I bind a Label without be inside datalist, datagrid?. I wrote a function that retrieves "salesman name" from an access database but somehow retrieves "System.Data.OleDb.OleDbDataReader" and not the data.

<asp:Label id="lbl2" runat="server" text=<%# GetSalesman()%>/>

Can I do this without the use of datalist, repeater or datagrid.????

Thanksss.

What does your function return?

-------------------------
I will only tell you how to do it, not do it for you.  
Unless, of course, you want to hire me to do work for you.

^^Thats my signature

Public Function GetSalesman()

Dim myConn AS OleDbConnection
Dim myCommand As OleDbCommand
Dim myReader As OleDbDataReader
Dim query As String
'specify the data source
myConn = new OleDbConnection ("Provider=Microsoft.Jet.OLEDB.4.0;data source=" & server.mappath("/db/uoi.mdb"))
'define the command query
query = "SELECT Distinct Nro FROM Clients,Salesman WHERE Salesman.Username='" & Context.User.Identity.Name &"'"

'create a command object and set its
myCommand = new OleDbCommand ( query, myConn )

'open the connection and instantiate a datareader
myConn.Open ( )
myReader = myCommand.ExecuteReader ( )

return myReader
'close the reader and the connection
myReader.Close ( )
myConn.Close ( )

End Function

First, your function is wrote incorrectly as these 2 lines

myReader.Close ( )
myConn.Close ( )

Will never get called. Move them above your return statement. If you want to bind the label to the result of that function, return a string. So something like:

Dim sString as string = myReader("column")

return sString

I'm still getting

Object reference not set to an instance of an object.


I move around those 2 lines you told me and add the string variable.

Can i bind a label without being in a datagrid, datalist or repeater

Now I'm getting

BC30311: Value of type 'System.Data.OleDb.OleDbDataReader' cannot be converted to 'String'.

Here is the problem: a datareader only contains data while you have a connection open to the database so returning a datareader from a function does you no good at all. You either A) have to return a datatable/set or B) Return a string value from your query. You will NOT be able to access any data outside of the above function using a datareader.

I create a function with a dataset but i'm getting Compiler Error Message: BC30408: Method 'Public Function GetSalesman(sender As Object, e As System.EventArgs) As Object' does not have the same signature as delegate 'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'.
--------------------------------------
Should i call the method as
Option1)
<asp:Label id="lbl2" runat="server" Text=<%#"GetSalesman"%>
or
Option2)
<asp:Label id="lbl2" runat="server" OnInit="GetVendedor">
If i do as option2 I get the above compiler error.

Whats wrong with just doing:

Private Sub Page_Load(ByVal sender as Object, ByVal e as EventArgs)
If not Page.IsPostBack
     lbl2.Text = GetSalesman()
End If
End Sub
