End

in Vb i have DatabaseManager Class Which Have this Code :

VB

Private Function exeReader(ByRef cmd As SqlCommand, ByRef dr As SqlDataReader) As Integer
        Dim retval As Integer = -1
        cmd.Connection = Me.Connection
        Try
            If cmd.CommandType = CommandType.StoredProcedure Then
                Dim pr As New SqlParameter("@retval", SqlDbType.Int)
                pr.Direction = ParameterDirection.ReturnValue
                cmd.Parameters.Add(pr)
            End If
            If cmd.Connection.State = ConnectionState.Closed Then cmd.Connection.Open()
            dr = cmd.ExecuteReader()

            If cmd.CommandType = CommandType.StoredProcedure Then retval = cmd.Parameters("@retval").Value
        Catch ex As Exception
            Throw New Exception(ex.Message)
        Finally
            Me.close()

        Return retval
    End Function

            Dim retval As String
            cmd = New SqlCommand("Get_Prices_Item_By_ID")
            daa.SelectCommand.Parameters.AddWithValue("@FirstUnitWholeSalePrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@FirstUnitShopperPrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@FirstUnitDemotionsPrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@FirstUnitPriceDefult", SqlDbType.Bit)
            daa.SelectCommand.Parameters.AddWithValue("@SecondUnitWholeSalePrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@SecondUnitShopperPrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@SecondUnitDemotionsPrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@SecondUnitPriceDefult", SqlDbType.Bit)
            daa.SelectCommand.Parameters.AddWithValue("@ThirdUnitWholeSalePrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@ThirdUnitShopperPrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@ThirdUnitDemotionsPrice", SqlDbType.Decimal)
            daa.SelectCommand.Parameters.AddWithValue("@ThirdUnitPriceDefult", SqlDbType.Bit)
            daa.SelectCommand.Parameters.AddWithValue("@DefultPrice", SqlDbType.Int)
            dr = cmd.ExecuteReader()
            Return retval
        End Function

And Business Class Code :

VB

    Return dt
End Function

Why have you posted all this code twice: Once is more than enough? Also your problem description is far from clear. Displaying data in a textbox is just a matter of capturing the data, formatting it to your specification, and setting it into the textbox's Text property.

Pretty much all you have to do is add a second parameter to your existing SqlReader code:

VB

Dim pr As New SqlParameter("@retval", SqlDbType.Int)
pr.Direction = ParameterDirection.ReturnValue
cmd.Parameters.Add(pr)
cmd.Parameters.AddWithValue("@ItemID", idOfTheItemYouWantToSearchFor)

Your reader can then fetch the values and add them to your textbox.
