Patient Banner Allergies Collection Binding

The PatientBanner's Allergies dependency property does not have a setter, and thus can not be binded to a view model's allergy collection when using MVVM patter.

To fix this a setter must be included as:

        /// <summary>
        /// Gets a collection of patient allergies.
        /// </summary>        
        /// <value>Allergy collection.</value>        
        [Category("Patient Details")]
        public AllergyCollection Allergies
                return (AllergyCollection)this.GetValue(AllergiesProperty);
            set { this.SetValue(AllergiesProperty, value); }
Once this is done, binding to the view model works, like so:


                          Width="750" Background="White" Canvas.ZIndex="99" FontFamily="Arial"
                          FamilyName="Evans" GivenName="Jonathan" Title="Mr" Gender="Male" DateOfBirth="12-02-2006" 
                          Identifier="606 172 4098" IdentifierType="NhsNumber" PreferredName="Jon"
                          Address1="98 Andover Place" County="Berkshire" Postcode="RG3 5AP" Town="Reading" 
                          HomePhoneNumber="(0118) 496 0337" MobilePhoneNumber="(07700) 900555" WorkPhoneNumber="(0118) 496 0338" 
                          Allergies="{Binding Allergies}">


I Kindly ask the team if this is the best way to go for this or if I'm missing something. Thanks

Sorry for the delay. Yes this is the correct way to go. We did not add a setter as it violates an fxcop rule, but with binding the case for for get and set operations for collections is strong. I will add a work item to cover this for our next release.
