Can sub-properties be hidden from the property grid?

I have a component that displays its properties in a property grid to the user. I am able to add custom properties, remove standard properties, etc. However, I want the user to be able to select the font used for the control. But, I only want them to be able to select the font name and size...none of the other stuff that is contained within the font. Is there a way to hide the other sub-properties?

Hi bdbull,

Based on my understanding, you want to hide the sub properties of Font in the PropertyGrid for your component, right? If so, you should custom a TypeConvert for the Font of your component. Try something like the following. It helps you hide the sub properties.

Code Snippet

public partial class MyControl : UserControl

{

public MyControl()

{

InitializeComponent();

}

[TypeConverter(typeof(MyFontConvert))]

public override Font Font

{

get { return base.Font; }

set { base.Font = value; }

}

class MyFontConvert : FontConverter

{

public override bool GetPropertiesSupported(ITypeDescriptorContext context)

{

return false;

}

If you want the use can only edit the Font name and size, you need to custom an Editor for the Font. Check the following thread for a sample about how to custom an Editor.
