I have a PropertyGrid (Windows Forms App) based component that uses
TypeConverters to generate ranges of acceptable values for properties. The
idea was that I could download the key/value pairs from a database and
manipulate the TypeConverters dynamically. The property grid then displays
the property with a drop down list.
It does work when I open the application for the first time. If, however, I
open the form and then open a second...

Hi All,
One :
I have a property that get/set a array of an abstract class A

my array is initialized with one element it works fine)
But I can not change the initial state of the array. It must be null.

Now I am developing a tool, just like VS.net Form Edition environment.
User can edit a component's properties by a PropertyGrid control.
Now I have some questions about this PropertyGrid control:
1. How to verify a property's validifity?
as you know, In VS.net, when we input a component name that is same with an
existed name in the propertygrid, an error message will pop up: "Invalid
property value".
Now, my question is, how to implement...

I have found a few samples of how to use the PropertyGrid control and have gained a decent understanding of it. But of course, as it usually the case, my needs go far beyond the simple examples shown in online samples. All the online samples show how to take a class...

I have a situation where I want to show a property when one object is selected in a PropertyGrid, but I want to hide that property when more than one object is selected. For example, lets say I have an object with a Name property that must be unique. If one of these objects is selected by a PropertyGrid, then I want to show the Name property in the PropertyGrid so the user can change the object's name. But, if more than one of these objects...

The propertygrid is a great control, but I would like to show a more
descriptive text for the properties in the control. I tried to find a
solution within the system.componentmodel but did not succeed.
As far as I know I can only show the user the property name I use in my
class, like "cubic_inches". I would like the user to see something like
"Cylinder cubic inches".
Is it in any way possible to associate a text to the name of the...

Hello,
I have used SqlMetal to generate the Dlinq classes for my database
schema. I have created instances of those classes and then tried
binding them to a PropertyGrid object through it's SelectedObject
property. Whenever a Dlinq object is bound, and a particular EntityRef
object within that class cannot be obtained from a query, it throws a
EmptySequenceException.
This is really not an issue from a "get" perspective, i.e. when an

Hallo,
I want do take a PropertyGrid a the UserInterface for the properties of a
graphical diagramm. My problem is that the names of the property has to
follow the rules of variable name declaration. How can I use a word like
"Size of Tick" as a property instead of "Size_of_Ticks"? Is it possible that
the seenable property name in the PropertyGrid is overwritten (only as a
caption) and the name of the variables stay?

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:

Here is the code in...
