Enum Replacement Character

Larry Caylor — Sat, 20 Jan 2007 09:51:06 GMT

While the EnumSeparatePascalCase handles many situations it would be nice to be able to specify a substitution character like an underscore that could be used to insert spaces when displaying a enum. For example in our organization all departments are represented by a three character abbreviation and I have an enum that looks like:

Public Enum UserType

HRA_Employee

HSA_Employee

Other_County_Employee

Community_Partner

Contractor

Vendor

End Enum

Since I can’t separate all of them on PascalCase I end up inserting underscores. This works but it would make the application cleaner if I could easily eliminate the underscores when displaying the information.

If you are loading the enum into a combo, then you can either turn off the Sorted property so it will be in natural order, or you can change the sort to go by the value rather than the text.

Hi,
How could I preserve the order of my enum list (may be by its value instead of alphabetic order)?

Thank you

Not right now. You could, however, accomplish this by creating your own EnumTextBox subclass and within the constructor, add a handler to the this.DataBindings.CollectionChanged event. Within this event, add a handler to the binding object's Format event. Within the format handler, call the MicroFour.StrataFrame.Tools.Common.GetEnumDisplayValue() method and change the event args. This will allow you to format the data going to the control.

If you want to allow the text box to be editable, then you'll also need to handle the Parse event of the binding object to reverse the process of the format event handler.

Any plans on adding this capability to the situation where an enum is bound to a text box control? Right now the "unformatted" enum is displayed.

[quote]It is documented yet?[/quote]

Kinda - it is in the "What's New in Version 1.5" . I guess it was not enough of a hint. We added the feature in order to localize enums -- those darn Brazilians. :D

Good assumption.

This is why I try to read every forum post....you never know what amazing little tidbit you'll find. This is very cool. It is documented yet? I assume this is available in 1.5.1?

Very cool :cool: Somehow I missed that one. Thanks!

You can use the new EnumDisplayValueAttribute that we added just for this reason. You just put the attributes on your enum values and when you build a combo box from the enum, you can just leave the EnumSeparatePascalCase values as their defaults and the enum's display values will be replaced with whatever you put in the string.

Public Enum MyEnum
    <MicroFour.StrataFrame.Tools.EnumDisplayValue("My Value #1")> _
    MyValue1

    <MicroFour.StrataFrame.Tools.EnumDisplayValue("My Value #2")> _
    MyValue2
End Enum

And since you're a C# guy (I think :))

public enum MyEnum
{
[MicroFour.StrataFrame.Tools.EnumDisplayValue("My Value #1")]
MyValue1
}

You can also pass a second value to the attribute constructor that tells it that the first value is a localization key rather than a literal string for replacement.
