Is it possible to use callbacks (like in the old days with C++/MFC) to display listview items? Or how about an observable collection that tells a listview that its data has changed?

Anything like that?

in vb.net to get the items in listview take this

dim name as string
dim ind as integer

for each items as listviewitem in listview1.items
       ' here you get the name of the item
          name = items.text ' or items
'here your get the index
          ind = items.index

next items

Using INotifyProprtyChanged with an obseravable collection is a good option.
Have a look here - http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/c86df936-853f-452f-ad98-7d2ac53958ff[^].

One way to achieve this would be to have your collection implement INotifyCollectionChanged (if using ObservableCollection is out of bounds), and use a mediator class to monitor the changes. Obviously you'd want to use INotifyPropertyChanged for individual items in the collection.

Would using a DataGridView be a better option? I don't want anything fancy - I just need the listview to update items that have changed (possibly hundreds of items changing every 2 or three seconds or so).

BTW, this isn't a WPF application...

I don't know that DGV would be a better choice. The fact that the listview supports virtualisation is a big plus. BTW - I figured it wasn't WPF.

You can use the VirtualMode in list view.

This way you can specify your own content in call back events.

ComponentModel documentation [solved]

I'm trying to create a Component that sits in the Forms designer component tray and contains additional subcomponents that can be selected and configured via the document outline view (or through a collection property of the main component).

I've looked at numerous code project articles and even peeking at some MS components that behave kind of like this (e.g. ListView), but I can't seem to get my sub-components to show up in the Document Outline.

The MSDN is non-helpful in this area, their "documentation" consists of is a 2 sentence blurb describing an esoteric example and then 10 pages of code that assumes an intimate understanding of the entire .NET component model.

Anyone know of a good source of documentation on this area, or better yet any tips on what I might try?

Thanks,
-Chris

[solved]
I figured out how to do it. In my main component, add a custom designer:

[Designer(typeof(MyDesigner), typeof(IDesigner))]
public class MyComponent : Component

Then in MyDesigner, inherit from System.ComponentModel.Design.ComponentDesigner and override a couple methods, shown below:

public override void Initialize(IComponent component)
{
   base.Initialize(component);

   _myComponent = (MyComponent) component;
}

public override System.Collections.ICollection AssociatedComponents
{
   get
   {
      if (_myComponent == null)
      {
         return base.AssociatedComponents;
      }
      return _myComponent.Subcomponents;
   }
}

Now my sub components are selectable via Document Outline, but suppressed in the component tray (so as to keep it tidy). Cool | :cool:

Linq and IEnumerable - case insensitive?

shn40023-Dec-09 16:31

I have this piece of code that "selects" from an Excel data stream and also from an XML one:
foreach (var ex in dataExcel)
{
ExcelRecs++;
IEnumerable<xelement> part =
from item in Partlists.Descendants("Partx")
where (string)item.Element("Part_name") == ex.Name
select item;

.....
}

How do I make the comparison "case INSENSITIVE"? that is either one of item.Element("Part_name") or ex.Name can be upper case and the other lower case, the == comparise would still be true.

Thanks for your help!

Use string.Compare.

var part = from item in Partlists.Descendants("Partx")
where string.Compare((string)item.Element("Part_name"), ex.Name, true) == 0
select item;
