Two quick questions...

Ulrik Mueller — Fri, 19 Jun 2009 08:26:02 GMT

1. I'm using ComboBox with enumerated lists. How do I override the enumeration text in the ComboBox dropdownlist ?

2. I'm trying to work with a BO entirely from code (C#) - creation, calling a method on the BO and finally disposing. I am getting blind onto the correct way of doing this. HELP......

Looking forward to hear from you all ;-)

Regards
Ulrik

C# versions:

To change text displayed in an SF combo that is loaded from an enum, set an attribute on each item within the enum:

[codesnippet]using MicroFour.StrataFrame.Tools

public enum eMailSendFormat {
  // This will now display "Acrobat (PDF)" in combo
  [EnumDisplayValue("Acrobat (PDF)")]
  Acrobat_PDF = 1;

  // This will now display "Comma Separated Values (Windows-CSV)" in combo
  [EnumDisplayValue("Comma Separated Values (Windows-CSV)")]
  CSV = 2;
}[/codesnippet]

The 'using' statement in C# (Using in VB.NET) are used to ensure that disposable objects get disposed. I.e. when the using block is exited, the item is disposed. This occurs whether the code runs it course, you break out of it or an exception occurs within the block.

[codesnippet]using CustomerBO customers = new CustomerBO() {
  customers.FillByCity("Munich");
} // calls customers.Dispose() automatically when this block exits[/codesnippet]

Hi Ulrik,

[quote][b]Ulrik Mueller (06/18/2009)[/b][hr]1. I'm using ComboBox with enumerated lists. How do I override the enumeration text in the ComboBox dropdownlist ?[/quote]

For this you can use the < EnumDispayValue() > from the MicroFour.StrataFrame.Tools, here is sample in VB:

[quote]
Imports MicroFour.StrataFrame.Tools

Public Enum eMailSendFormat As Integer
< EnumDisplayValue("Acrobat (PDF)") > _
Acrobat_PDF = 1

< EnumDisplayValue("Comma Separated Values (Windows-CSV)") > _
CSV = 2
End Enum

I am not sure I totaly understand your request here, but here is sample in VB of how to use a SF BO:
[quote]
Using bo As bizItems = New bizItems
bo.FillByPrimaryKey(pPK_Items)
If bo.Count = 1 Then
Return bo.ItemName
Else
Return String.Empty
End If
End Using
