Hi Guys,

Okay, so I've not managed to find anything to help me with this on Google (although I'm not sure I have been searching for the right thing, if not I apologize).

My question is,

If I have a view model like such:

C#

internal class NewDataEntriesViewModel
{
    private CRCSubmissionDataEntry m_Entries;
   
    public NewDataEntriesViewModel(CRCSubmissionDataEntry; dataEntries)
    {
            m_Entries = dataEntries;
    }

    #region Properties
    [Description("Entry Name")]
    Public string EntryName
    {
       get {return m_EntryName;}
    }
    #endregion

}

In my View for this ViewModel, how can I bind a label to the Description attribute on my property?
Is this even possible?

Thanks.

I have a large viewmodel, about 20 properties,
on the view each one needs a label to go with its data entry. I have a choice, I can either create another 20 properties just for the label text, or I can use attributes on my viewmodel, and bind to the same property as its data entry control to display its name.

I don't really want to have 40 properties on a viewmodel, 20 is to many in my opinion but I've not found a way to reduce that yet.

It also means you can clearly see the associated friendly name of a property in your code.

Yes, it is possible. You can do it using Reflection. Check this

I finally found a solution!

The following thread gives details on how to create a Converter to use with the databinding. It could easily be enhanced to to different types of attributes, however it is hard coded for the description attribute which is perfect for my requirement.

It was partial down to Syed's comment about reflection that helped me find it.
