I want to display custom data in some sort of control on a web page.
By custom data I mean it's not in a database yet it just resides in a
List Box on a different tab . I just want to display the data and
allow the user to edit a couple values. What control can I use that
will allow me to manually fill it with whatever data I want and allow
user editing?
(using: asp.net 2.0, vb.net, visual studio 2005, winxp pro sp2)

Most, if not all, of the databinding-compliant controls can work with pretty
much any data source, not just those fetched from a database.
E.g. it's perfectly possible to instantiate a DataTable object, define its
structure, and add rows to it so that e.g. a GridView can be bound to it... http://msdn.microsoft.com/en-us/libr...datatable.aspx

Okay I've got my data table made and now it's bound to my DataGrid. I
have some columns in my DataGrid that I need to allow the user to
edit. Do I need to create all of the Edit Item Template fields
programmatically then?
I tried creating the columns and templates in the DataGrid (using the
Wizard) and then bind the data table to the DataGrid programmatically
but my columns just append to the columns I had defined with the
wizard.

Do yourself a *HUGE* favour and ignore all of these wizards - IMO, they
cause more problems than they solve...
1) Create your DataTable and populate it.
2) Create a GridView manually (why are you still using a DataGrid, AAMOI?)
and define the columns to match those in the DataTable.
3) Bind the GridView to the DataTable.

Okay that is what I did but I am not getting correct results in my
GridView. In the Design view of my aspx page I clicked on the
GridView and chose "Edit Columns" (this is the wizard I was referring
to earlier) and I added 6 columns as BoundFields named exactly like
the columns in my DataTable. Then in my vb code I bind the DataTable
I have created and populated to the GridView the DataTable columns
just append to the GridView control. The first 6 columns don't have
any row data and the next 6 do.

I made a couple of the fields template fields (so I can allow editing
now) but I am getting this error "Exception has been thrown by the
target of an invocation." It is referring to this line in my aspx

<ItemTemplate>
<asp:Label ID="lblDuration" runat="server" Text='<%# Bind("[Duration

Can anyone show me how I would enable editing for the "Resource"
column? For example, upon editing for the resource column I want a
drop-down list of items they can choose from. I added a command field
to my GridView and I made the resource column a template field but
when I click edit my drop-down box for the resource column does not
appear.
