Hi all
I suppose this is a elementary question but I am totally new so please bear with
I have a field called Sex char(1) where the values can either be "M" or "F". I want to use a radio button for the selection where the values of the Radio button must be Male and Female. I would like to specify the value within the BO. Is this possible.
Thanks
Willie

I'd create a custom, bindable field in the BO that translates the "M"/"F" into 1 and 2 (which can then be bound to the radio button group). See the Adding Custom Field Properties topic in the SF help file for more information on custom fields.

Thanks Greg
Done it and now the form is displaying. However, when I would edit it and select a value it runs into a neverending loop within the set.
Here is the custom property code :
#Region " Custom Field Properties "
''' <summary>
''' sex
''' </summary>
<Browsable(False), _
BusinessFieldDisplayInEditor(), _
Description("Sex Radion button field"), _
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _
Public Property [sex_radion]() As System.Int32
Get
Dim loValue As Object
loValue = Me.CurrentRow.Item("sex")
If loValue Is DBNull.Value Then
Return 1
Else
If loValue = "F" Then
Return 2
Else
Return 1
End If
End If
End Get
Set(ByVal value As System.Int32)
If value = 1 Then
Me.CurrentRow.Item("sex") = "M"
Else
Me.CurrentRow.Item("sex") = "F"
End If
End Set
End Property
#End Region
I also added the follwoing:
Protected Overrides Function GetCustomBindablePropertyDescriptors() As MicroFour.StrataFrame.Business.FieldPropertyDescriptor()
'-- Create and return a new array of FieldPropertyDescriptor
' objects that contains the ReflectionPropertyDescriptor
' for the cust_fullname field.
Return New MicroFour.StrataFrame.Business.FieldPropertyDescriptor() { _
New MicroFour.StrataFrame.Business.ReflectionPropertyDescriptor( _
"sex_radion", GetType(AgentBO))}
End Function

I'm not seeing anything obvious in this code that would start an infinite loop. I'd step through the code, starting with whatever action causes the loop to occur. Likely you have some other code that is responding to this action that is causing the loop.

Hi Greg
Ok, got the problem. In my radio button, hidden behind the other there were another 3 buttons. It seemed that the value of one of them also had a value of 2.
Thanks for the help.
