Question about PropertyGrid

[Lost User]

Hello... I have a problem. I try to show all property in my object into a propertyGrid. My class is something like this :

class MyClass
{
public Parent parent = new Parent();
}

class Parent
{
public Child child = new Child();
}

class Child
{
public string text = "Hello Child";
}

If I create a new instance from MyClass and put it in property grid, I can only see a gray text from "Parent". But I cannot go into it, to see the "Child". There are no "+" sign. How to make "Child" also editable in property grid ? Thanks...

in order to work with that control, you need to define some properties within your class(es), don't you think?

class MyClass
{
private Parent parent = new Parent();
public Parent ParentInstance
{
get { return parent; }
set { parent = value; }
}
}

class Parent
{
private Child child = new Child();
public Child ChildInstance
{
get { return child; }
set { child = value; }
}
}

class Child
{
private string text = "Hello Child";
public string Text
{
get { return text; }
set { text = value; }
}
}

I change the member variable into properties. It doesn't work also. Probably there are some attribute to make the properties in child class visible...? I can only see "ParentInstance" gray and not editable or clickable....

of course you must use attributes. Have a look here[^] first, then do what you have to do, after you undestand what you are doing ;P

Hi, You must explicitely tell the PropertyGrid to show subproperties. To do that, the easiest way is to assign the ExpandableObjectConverter to your Parent and Child classes, like this:

[TypeConverter(typeof(ExpandableObjectConverter ))]
class Parent
{
private Child child = new Child();
public Child ChildInstance
{
get { return child; }
set { child = value; }
}
}

[TypeConverter(typeof(ExpandableObjectConverter ))]
class Child
{
private string text = "Hello Child";
public string Text
{
get { return text; }
set { text = value; }
}
}
