I have created a custom class inheriting CollectionBase and implementing
IBindingList. I am binding the list to a datagrid. I would like to have a
property on the class that works like the RowState of a DataRow that can
tell the datagrid not to display the item anymore after it is marked for
deletion by the user. I have a property on the class that indicates whether
the item is Added, Unchanged, Modified or Deleted.
I would like to...

I have a Collection that inherits from CollectionBase and Implements IBindingList which I have bound
to a DataGrid. So far everything works fine.
However, I am missing one piece to the IBindingList that I haven't figured out yet, how to determine
which DataGrid column header I clicked on so I can do a custom sort. Right now the sort is rotating
just to see that everything works.
There are two pieces of the IBindingList that I didn't...

I want to be able to fire event when the data source was changed
The data source is data objects in array list (which does not know to
notify)
Is it possible to use control's functionality (e.g. DataGrid) to catch the
update of data source (DG updates with add to data source)

Hi all,
New to .NET, I'm working on an Winforms client application using VS
2005 beta2. My needs considering data storage are the followings:
(1) Small files (0 < length < 10 mb), containing lots of small
'objects' that need to be loaded into memory at runtime, in order to
garantee small access time to each 'object'. Each of these 'objects'
collection should be able to easily bind to a DataGridView, AND to
provide *filtering* and...

I've looked around and have yet to find anything that would answer my
question regarding formating a column in a datagrid. My grid looks like
this as far as data"
AMHQCON|51300.01|-3147
The first two columns are pretty much text column, but subsequent columns
1-12 are numerical. I'm trying to get the thousand separator to work. Any
ideas?

Trying to learn about manipulating collections of objects, and populating
these objects dynamically from datasources. Could someone post a code sample
that shows the following:
Instantiating a collection object -- say, a dictionary.
Populating that collection object with custom objects, say, Person. What I
really want to see is how to populate the properties of those Person objects
from a datasource: instantiate one Person, fill...

My application needs to present data generated at run time in a datagrid that
can be sorted by clicking on columns, and where rows can be selected and
events generated.
Do I need to set up a dataset and datatable to do this or can I do this
through arrays (which I believe can not be sorted in a datagrid)?
Can anyone point me towards any samples or in the right direction?
thanks much - Jon

I am stuck on trying to generate two columns headers for a datagrid on
form load. I can use a datatable as the datasource and get the results
I want, but I want to set different column widths and don't see a way
to do this through the datagrid properties. I am not using a database
connection, I just want to set column headers on the datagrid. I am
somewhat new to vb.net. Here is the code I am using. This code works

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
