ConditionalAppearance - How do I customize the item caption text based on a certain condition

Set Class and Property DisplayName dinamically

created 12 years ago

Hi,

I would like to change the display (XafDisplayName attribute) name of one of my businessclass. It has a string property, and I also would like to change the display name for it.

This is the constructor of my class, where I'm trying to achieve it:

C#
public PopUpTextEdit(Session session, string formCaption, string textCaption) : base(session)  
{  
    this.ClassInfo.AddAttribute(new XafDisplayNameAttribute(formCaption));  
    this.ClassInfo.GetMember("Text").AddAttribute(new XafDisplayNameAttribute(textCaption));  
}

But this approach does not work. Can you tell me what do I do wrong? Or how can I change those properties dinamically. This class is btw a non-persistent class, but I don't think it makes any difference.

Thanks in advance!

    Maybe I have to rephrase my question to the following: How to add/edit class or property attributes dynamically at the constructor of the business class (or at any of the init events)?

    Hello Balázs,
    You can add/remove attributes dynamically in the ModuleBase.CustomizeTypesInfo method. Feel free to contact us if you have any difficulty with this approach.

        Hi Manuel,
        Thanks for the sample, I did not solve the way you did, but you gave me an idea how to achieve the behavior I wanted.

          I am happy to hear that you have found a solution,
          From my side, I suggest you use another approach: handle the WindowTemplateController.CustomizeWindowCaption event, as shown in the How to: Customize a Window Caption article. Hope you find it helpful.

            Hi Anatol,
            Well my aim was not just to change the window caption, but also the label for a single text editor, so your approach does not really fit into it. Anyway thanks for the suggestion.
            My solution was to add 2 properties to the business class (Caption, TextLabel) and I set them thru the contructor of the class. I also created a viewcontroller targeted to this class's detailvew and in the OnActivated function I just simply replace these labels with the actual values. It works just fine, and it's quite simple.
            My problem was, that I tried to control the view from the model, which was wrong approach.
