Hi Folks,

I would like to know if there is a way of Hiding entire category from a PropertyGrid (PG)

I have been using the Browsable(False) attribute on property that I need want to be displayed on the PG. Then when all properties belonging to a perticular category have been browsabled-false the category automatically dispeared.

However, I still have the a category that are still present and that is the Design category.

It contains the Name and Locked properties, but I would like to remove them too.

Is anyone knows how to get around doing that?

Thanks

you can try implementing ICustomTypeDescriptor and override the PropertyDescriptorCollection being queried by the designer for the properties. I believe these Design Categorized properties are added on the fly by the designer so this might not work but you can try it.

I have solvented this issue using a TypeConverter in my components. The following line implement a custom TypeConverter for a component:

[TypeConverter(typeof (MyCustomTypeConverter))]

The class called 'MyCustomTypeConverter' must inherits from the ExpandableObjectConverter class.

for example:

public class MyCustomTypeConverter: ExpandableObjectConverter

In this class, you must implement the use of Properties Attributes objects. Using properties attributes, you can to define an attribute or category called 'MyFilteredProperties' and looking for this to return  in a PropertyDescriptor collection.

 

See more details at:

10x to zeeuw for the article.

If you use the supplied code, you must to change some lines for hide unwanted properties.

At the public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes) function, you must to add some like this:

....
.... previous code ommited

// For each property use a property descriptor of
// our own that has custom behaviour.

ArrayList orderedPropertyAttributesList = new ArrayList();
foreach (PropertyDescriptor oProp in baseProps)
{

PropertyAttributes propertyAttributes = GetPropertyAttributes(oProp, value);
if (propertyAttributes.IsBrowsable && propertyAttributes.Category == "\rMyFilteredProperties")
{
orderedPropertyAttributesList.Add(propertyAttributes);
deluxeProps.Add(new PropertyDescriptorEx(oProp, propertyAttributes));
}

}

orderedPropertyAttributesList.Sort();

...
... subsecuent code removed....

Hi
I have followed the steps you have written and i am able to filter based categories and display name etc.. but i have an issue with 'Design' category even if i filter the' Design' Caterory it still appears in the propertygrid with the "Locked" property .take example the Name property inside Design Category is getting filtered automagically when you filter the Design Caterory but the 'Locked' property is not gettting filtered, i tried to filter based on Display Name but no success during debugging i found property collection is not having the Locked property itself how to overcome this issue on the fly it is getting added.

thanks in advance
