Filter by custom Category

[Art Kedzierski]

I have an object with custom properties. The only properties I wish to display in the property grid are those of category "MyCategory". How would I do that programatically?

protected string myproperty;

[Category("MyCategory")]
public string MyProperty{ get; set; }

I'm already setting the item and populating the RadPropertyGrid; it's the filtering I'm stuck on.

RadPropertyGrid1.Item = n;

Hi,

There are several options for you to achieve this. The first of it is to use the Browsable attribute to indicate that the property should not be processed. In case you are using autogenerated PropertyDefinitions, you can cancel the unneeded fields on the AutoGeneratingPropertyDefinition event. The last option is to set these PropertyDefinitions' Visibility to collapsed. However, I would advise you to stick to the former two options, as the latter one is designed to target slightly different scenarios.

That did it! Here's the code for future reference:

private void AutoGeneratingPropertyDefinition(object sender, AutoGeneratingPropertyDefinitionEventArgs e)
{
    AttributeCollection attributes = TypeDescriptor.GetProperties(RadGridView.SelectedItem)[e.PropertyDefinition.DisplayName].Attributes;

    CategoryAttribute cat = attributes[typeof(CategoryAttribute)] as CategoryAttribute;
    if (cat.Category != "MyCategory")
    {
        e.PropertyDefinition.Visibility = System.Windows.Visibility.Collapsed;
    }
}

Thanks!
