Hi Terry,
Thanks for your response. For the further question you mentioned, IMO,
DataGrid is a good one for displayed multi-column and customized data. Also
as for selecting , of course, it has buildin select feature let a user to
select a certain row. Though it didn't support buildin selection by double
clicking a row(generally we need to put a select button or link on each row
for seelction), we can manually provide such feature through some
clientside scripts. However, the main problem is that since DATAGRID is a
template databound control which can only populate data through databinding
and didn't expose such as "Items" collection like CheckedBoxList, so we can
not discretionarily modify individual item's index in all the items within
it. Thus, it's not quite possible for you to implement the move up/down
item function on using datagrid.
Thanks,
Steven Cheng

| I have a couple of problems with the CheckBoxList control which is leading
| me to look for a more appropraite control.
| Problem 1) In some instances I need to display more than one column of
| information
| Problem 2) The user need to be able to select a row and the control needs
to
| indicate which row is selected (like a list box does)
|
| With these problems in mind, is there a control that you would suggest?
The
| datagrid comes to mind but I dont think this control has inbuilt ability
to
| allow the user to click on the a row to select & highlight and highlight
| this row.
|
| I'd appreciate advice on this
