I have a DataGrid bound to a custom collection that
implements IBindingList. The collection returns true for
AllowNew. The collections AddNew() method creates a new
object, adds it to the collection and returns the new
object.
The SupportsChangeNotification property returns true and
the appropriate ListChangedEventArgs are used in the
ListChanged event. All fine no problem. However:

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...

Where can i find a good example of an ArrayList bound to a datagrid that
automatically updates the grid when the public data within the class
contained in the arraylist is updated. i do not want to use
datagrid.refresh() because the data updates randomly and often frequently
and refreshing the whole grid several times a second is expensive and causes
a flicker.

Hi, is there any way to format and order the columns displayed in a datagrid
bound to a class that inherits from IBindingList? i have used
DataGridTableStyle and added DataGridTextBoxColumns to it in the correct
order which works fine if the dataGrid.dataSource = "ArrayList", but it
doesn't work for my IBindingList wrapper.
If i bind the datasource to the arraylist method then the
ListChangedEventHandler is never invoked and my grid only...

Here is a snippit which replicates my issue. I have a datagrid which contains
an input textbox on each row, binded on the serverside. However it seems that
when I perform a postback to refresh teh numbers, they are not changing due
to the foreach loop I have in this code. When I comment out the foreach loop,
the numbers refresh fine (but the text boxs ovbiously no longer get created).
I have placed this code in the OnItemDataBind method,...

hello,
new to vb.net, have a few questions about DataGrid. I have a dataGrid
that is working pulling a dataset back from a stored proc and binding
to the datagrid for display
the datagrid's first column is a textbox(TemplateColumn), the other 3
columns are just display(BoundColumn).
(1) if the value of the textbox is 0, then i'd like to change it null,
so the box is empty
