Non Browsable property is stil visible

[saravanan M]

The property is visible in property grid, even after setting the browsable attribute to false.Why?

public partial class Myobjects : Page
    {
        public Myobjects()
        {
            InitializeComponent();
            radPropertyGrid1.Item = new Customer();

        }

        public class Customer
        {
            [Browsable(false)]
            public int Id { get; set; }
            public string Name { get; set; }
        }
    }

Hello Saravanan M,

In the current version of RadControls, RadPropertyGrid does not respect the Browsable attribute. However, we plan adding support for some attributes (including Browsable) in the future versions. The current recommended approach in scenarios with autogenerated property definitions is to subscribe to RadPropertyGrid's AutoGeneratingPropertyDefinition event, in order to cancel the generation of  any unwanted entries.

All the best,

Hello,

using the latest internal build (2013.2.805.45) I still face a problem with Browsable.

I extend a Linq2Sql class like this.

[MetadataType(typeof(Material.DAMetaData))]
public partial class Material {
    private void Test() {
    }
    public class DAMetaData {
        //works
        [Display(Name = "The Name", Order = 1)]
        public object Name { get; set; }

        //works
        [Display(Name = "The description", Order = 2)]
        [ReadOnly(true)]
        public object Description2 { get; set; }

        //works
        [ReadOnly(true)]
        public object Replaces { get; set; }

        //works and does what Browsable(false) should do
        [Display(AutoGenerateField = false)]
        public object Description3 { get; set; }

        //NOT working
        [Browsable(false)]
        public object SearchDescription { get; set; }

    }
    }

In the comment I showed what is working an what not.
Since Display(Autogenerat.... works this is not a big problem. I just wanted to inform you.

Hello Manfred,

I have tested the case and Brosable(false) is applied correctly. Will it be possible to check out the sample attached and verify whether I am missing anything ?

Hi Maya,

YES you missed something in your project.

First please add a reference to System.ComponentModel.DataAnnotations.
Next please change the club as follows; (you can copy it there replacing the existing lines).

...
using System.ComponentModel.DataAnnotations;

namespace RadGridView_WPF_AR_16
{
    /// <summary>
    /// A football club.
    /// </summary>
    [MetadataType(typeof(Club.DAMetaData))]
    public class Club : INotifyPropertyChanged
    {
        public class DAMetaData {
            [Browsable(false)]
            public string Name { get; set; }
            [Display(AutoGenerateField = false)]
            public int StadiumCapacity { get; set; }
        }

        public event PropertyChangedEventHandler PropertyChanged;

        private string name;
        private DateTime established;
        private int stadiumCapacity;

        public string Name
        {
...

I removed Browsable from the Name Property.
Instead I used a nested Metadata class and applied the Annotations there.

As I wrote in my first post I have to use this kind of Metadata assignemet since my classes are generated by SQLMetal (linq2sql).
By the way - your example works in it's original  form.

[Browsable(false)] attribute in MetaDataType class is still not working, i am using your latest build.

[MetadataType(typeof(Club.DAMetaData))]
public class Club : INotifyPropertyChanged
{
     public class DAMetaData {
            [Browsable(false)]
            public string Name { get; set; }
            [Display(AutoGenerateField = false)]
            public int StadiumCapacity { get; set; }
     }
}

[MetadataType(typeof(Club.DAMetaData))]
public class Club : INotifyPropertyChanged    {
public class DAMetaData {
[Browsable(false)]
public string Name { get; set; }
[Display(AutoGenerateField = false)]
public int StadiumCapacity { get; set; }
 }
}

Hello Abdul,

I modified the sample previously attached with the latest binaries and the Browsable attribute is respected appropriately. Check out the newly updated project and let me know in case there is some misunderstanding on the issue.

Hello Maya,

I checked your modified sample, and it is working.

BUT, in my case it is not working, because I am using multiple objects in property grid.

you can observe this issue when you will modify your sample as

<telerik:RadPropertyGrid Item="{Binding Clubs}" PropertySetMode="Intersection" />

in above change i added PropertySetMode="Intersection" and changed Clubs[0] to Clubs.

could you plz tell me why MetaData annotation is not working when we use multiple objects with PropertySetMode=Union or Intersection.

Hello Abdul,

Indeed, you are right. I tested the case when working with property sets. I logged the issue in our system for further investigation. You can follow its progress from the Feedback Portal.
