Filter elements in PropertyGrid

In System.Windows.Forms there are a PropertyGrid that displays properties of an attached object. Let's say MyTextBox : TextBox.

Now, I would like to display on it some MyTextBox properties, say only Size, Location and my custom property Date.

More that than, I would like to be able to change the real property names, say "Dimension", "Location" and "Starting Date".

I saw two projects on this subject : first and second, but first does not work well(for browsable properties), and the second seems to add an event for each property changes, this is not acceptable.

You should be able to hide them with a [Browsable(false)] attribute. If you want to change the name, you need to write your own TypeDescriptor as seen here

Yes, but I wrote about a TextBox. I can't override all TextBox's properties with Browsablefalse attribute.

My fault... I totally overlooked the base class. You can use the same technique in the CustomTypeDescriptor I listed to filter out the properties you want as well as change their names.

same technique (?).. hmm.. I tried the code it don't compile (undefined method GetFriendlyname in FriendlyNamePropertyDescriptor class) marked: "// replace with code to return a friendly name" but what should I replace there?

That's where your code would go to say "if this property is called Size, call it Dimension instead." As far as "same technique" I mean in the ICustomTypeDescriptor GetProperties method implementation, you can filter out the properties that you want to return.

so..., as I understand, I need a method with a big if else for each property name and its DisplayName... so this solution will not be universal, but for a component... maybe..

Well, there is a "DisplayName" attribute that you could use, but you would then need to decorate every property. So, yeah, this is component specific.
