tying column value to enum in Browse Dialog

Marcel Heitlager — Thu, 23 Aug 2007 16:12:38 GMT

I'm trying to tie a column value to an enumeration text value in Browse Dialog result.

[codesnippet]

Public Enum PlanTypes As Integer

Standard = 0

Interest = 1

Custom = 2

CustomInterest = 3

End Enum

[/codesnippet]

My bo has a field called plan_type which contains the integer key.

What value do I change in the RowPopulating event?

Thanks.

Thanks for the help. What you put in the last post is actually what I wanted to do.

This works the very same way as the ListView. First, have you tried to just allow the enum to populate within it. By default, any strong-typed column using an enum will attempt to perform a ToString which shold return the enum value without you having to do anything in the RowPopulating. However, if you choose to go the RowPopulating route, just set the column that will house this value to PopulatedThroughEvent rather the a formatted value. Then set the event args value when the event is raised:

[codesnippet]With CType(e.BusinessObject, MyBOType)
e.Columns(1).DisplayValue = .MyEnumField.ToString()
EndWith[/codesnippet]

A better way to parse the enum is to provide an attribute so you can get a more accurate display description:

[codesnippet]Public Enum MyEnum As Integer
    <MicroFour.StrataFrame.Tools.EnumDisplayValue("Apple", False)> _
    Item1 = 0
    <MicroFour.StrataFrame.Tools.EnumDisplayValue("Orange", False)> _
    Item2 = 1
    <MicroFour.StrataFrame.Tools.EnumDisplayValue("Pear", False)> _
    Item3 = 3
End Enum[/codesnippet]

Then parse it out this way:

[codesnippet]e.Columns(1).DisplayVaue = MicroFour.StrataFrame.Tools.Common.GetEnumDisplayValue(.MyEnumField)[/codesnippet]
