Auto generating rows based on attributes

[Chris]

Hello,

PropertyGrid looks promising but I'm struggling to make it work as I'd like. I want to be able to specify properties to display based on annotations in my View Model. Is this possible? I have tried applying the [Browsable] attribute and this works to an extent but you have to explicitly set [Browsable(fase)] on properties you want to exclude. In my case the View Model inherits from another class, so it is including all the properties from the base class and it is not my code so I can't add annotations to control these.

Is there any way to 'opt-in' to displaying properties? i.e. Only properties that are annotated will be displayed.

 

Thanks

Hello Chris,

What you could try is to subscribe to the AutoGeneratingPropertyDefinition event of the RadPropertyGrid. In the event handler, you can get the attributes set to the property and if given attribute is set you can cancel the generating of the field.

I have created sample project which demonstrates this approach. The project is attached to this reply.

Thanks Dinko. Based on your code I came up with this which works better for me as I have inheritance so not all my objects are of the same concrete type:

private void RadPropertyGrid_AutoGeneratingPropertyDefinition(
    object sender,
    AutoGeneratingPropertyDefinitionEventArgs e)
{
    var property = e.PropertyDefinition.PropertyDescriptor;
    var browsable = property.Attributes.OfType<BrowsableAttribute>().FirstOrDefault();

    if (browsable == null || browsable.Browsable == false)
    {
        e.Cancel = true;
    }
}

 

Thanks

Chris
