I'm not sure what you're asking.

Do you need to dynamically load the mydll Assembly?

No. I can load my assembly.

What i need is to load the values of my properties from the xml file.

I'm serializing the values of my properties, but if the property is a basic type (int, float, string...) there is no problem, the problem is when my property is the type Myclass, I can not load again my values.

Edit the subject then since your question is not about loading an assembly but rather serialization

Sorry, but the ploblem is not with the serialization, is loading the data.

The error always says that is not possible to load the assembly.

Any way, thank you

I have a winforms application (C# 2008 Express Edition), and I want the user to be able to drag and drop the columns to a different position in the DataGridView.

The DataGridView is unbound, and is populated with data on opening of the form, the columns are programmatically set.

I have "AllowUserToOrderColumns" set to true, but i can't reposition the columns.

Is it possible to reposition columns, and if so how do I accomplish this.

TIA,
Rob

PropertyGrid fails to group a property marked as being in Category Behavior.

Re: PropertyGrid fails to group a property marked as being in Category Behavior.

Hmm this is funny, I've made some classes with some properties, and I wanted them to be grouped into categories in the propertygrid. so ofcause I added the Category Attribute and set the value to Behavior, and wouldn't you know it, the PropertyGrid Groups it as Type ??? anyone ever seen this ??
Heres an sample class

public class Demo
{
    [Category("Behavior")]
    public int Total
    {
        get;
        set;
    }
}

Try display this in the PropertyGrid. perhaps its only my computer that makes this fault. WTF | :WTF:

With great code, comes great complexity, so keep it simple stupid... $Shucks | :-\$ $Shucks | :-\$

I've tried using your code, and it seems to work;

public partial class MainForm : Form
{
    PropertyGrid grid = new PropertyGrid();
    Demo myDemo = new Demo();
	
    public MainForm()
    {
        InitializeComponent();
		
        grid.Dock = DockStyle.Fill;
        grid.SelectedObject = myDemo;
        Controls.Add(grid);			
    }
}
public class Demo
{
    [Category("Behavior")]
    public int Total
    {
        get;
        set;
    }
}

Are you inheriting from Object, as the snippet suggests?

Windows XP, 32 bit. I'm getting a category-heading as expected, both with .NET 3.5 as with 4.0.

Is it only reproducable on 64-bit Weven?

Dont know, will look into it tomorrow on work... but its kind of funny dont you think ? Wink | ;)

I think i will try different kinds of OS's and 32 & 64 bit versions to see if i can get the fault.

But still i dont know why... i have asked microsoft, but still no answer...

That it is - I'm curious what caused it.

Over Microsoft Connect?

Yes over Connect... the reason I posted it here, was to see if others had the same experience.

When i get the answer i will post it here.

Just a short follow up: The same happens on a Vista 64 bit.
So the error/bug is now confirmed on the following OS:
- Windows 7 (64 bit)
- Vista (64 bit)

Its running correctly on (No bug):
- Windows 7 (32 bit)
- Vista (32 bit)
- Xp (32 bit)

Ok so heres the real bug, although its not really a bug, its more a culture thing.
When running the propertygrid in the danish language, the following CategoryAttribute will be translated:
Category("Appearance") = Udseende
Category("Behavior") = Type (the correct word for this would be "adfærd" or "opførsel" and NOT Type)
Category("Data") = Data
Category("Font") = Skrifttype
Category("List") = Oversigt (the correct word for this would be "List" or "Liste" and NOT Oversigt)
Category("Misc") = Diverse
Category("Position") = Placering
Category("Scale") = Skalering
Category("Text") = Tekst

I didnt consider the culture thing because translating Behavior to danish is not ~~Type~~

I've posted the information on my blog here: C# and I[^]
