I have a DataTable which i have added data to.
I have a custom method that prints a DataView of the DataTable out on the
screen. The problem I'm having is, i need to call the custom method
whenever the DataTable is changed.
How can I do this? this is not a standard binding problem, since I need to
call a custom method to paint the items on the screen.
view.ListChanged += new ListChangedEventHandler(this.view_Changed);

I'm having a bit of a problem with my DataList when I try to update from the
user's input. I've included relevant excerpts at the end of this message. In
the UpdateCommand code, the "PageLevelTextBox" appears to be found (it isn't
returning null), but the Text property is an empty string ("").
Am I missing something really obvious?
Thanks
Colin

I have a Datagrid that is bound to a Datatable at runtime. I allow the
user to select a number of rows using the mouse and then click a button
that says "check selected rows", which then cycles through the selected
rows and sets a check box field in the datagrid (and thus the databound
datatable) to checked/true. It works like this:
Dim cel As DataGridViewCheckBoxCell
For Each row In DataGrid.SelectedRows
cel = row.Cells(0)
cel.Value =...
