Hi,
I have a objectA with a property that return an object B (accessor GET only)
I have defined an ExpandableObjectConverter on the type B and overrided
CanConvertTo, CanConvertFrom, ...
The problem is that can not edit the object B (the proerty in greyed) in the
propertyGrid (I can edit these properties but not the object directly
because, it doesn't have SET accessor)
In fact, when I edit this object, I woul like to change just the...

I have created ExpandableObjectConverter in C#. for use in
System.Windows.Forms.PropertyGrid.
The property grid shows the DiffItem is a object that holds member
TheItem.
without expanding TheItem
It works if u click, select from drop down box. until you DoubleClick
it shows error:
"Invalid property Value". with "Object type cannot be converted to
target type."

Hello.

I made a ExpandableObjectConverter subclass but its GetProperties method is
not called when my object is set as a Converter of PropertyDescriptor. The
thread above gives a good explanation of the problem, but...

Hello.
I have an ExpandableObjectConverter subclass that I associate to the
'Converter' of a custom property descriptor.
After I changed my .net code to the new syntax (VC 2005), the
GetProperties method of my converter class is not called anymore by
the PropertyGrid. Now my expandable properties always show a property
'Length' with value 0.

Ok here is the problem. I have a struct property on an object that I
want to edit with the property grid. One of the properties of the
properties of the struct is supposed to be read only to the user.
The inital problem is that when you use the ExpandableObjectConverter
as the type converter the values reset themselfs back to their orginal
values. Most likely because the Propertygrid has a copy of the value
and not the value itself.

Hi,
I'm using classes with the ExpandableObjectConverter attibute in a
UserControl for properties. This works fine for some classes, and properties
of these classes can be edited during design time.
However, classes which are derived from CollectionBase don't save their
values in the form's code. Properties can be changed in the VStudio property
editor but they are not persistent:
// Property values are saved in the forms code.

Hi!
I've written a custom ExpandableObjectConverter in which I have overridden
GetPropertiesSupported and GetProperties (and some more). By setting
breakpoints in all methods I have found out that only GetProperties never
gets called, however all other methods are called correctly. (The respective
class has the TypeConverter attribute set.)
Does anyone have a clue about what this situation might cause?

I've created a usercontrol with a Person property. The Person property
returns a Person object. I've also created a PersonConverter class which
inherits the ExpandableObjectConverter so the Person property is expandable
in the PropertyGrid. This all works fine.
I've also created another usercontrol that also has a Person property and
returns a Person object. But in this usercontrol I don't want the Person
object to be expandable.

Hello,
i am doing a custom class for my property for a property gird using
ExpandableObjectConverter.
I have a class (CustomFontClass) that uses a Converter which inherits
the ExpandableObjectConverter. everything works fine, but the only

I have followed the http://www.codeproject.com/KB/vb/using_propertygrid.aspx

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
