operations, but we run into this scenario. I just would like to see some
comments on it.

we have dataset cached which has large ammount of data.

Hi,
I'm working on a Windows applicaton with VS 2003 on windows 2000. I have a
listbox that I have binded to a dataset table, "source" which has 3 columns.
I would like to display 2 of those columns, "scode" and "sname", as 1 column
(if not possible then 2 columns will be fine) in the listbox. Can the
listbox display 2 columns information from the dataset and how can I do that?
Also, I set the property of the listbox to selectionmode...

Hi,
What are the main differences between a dataset and a dataview?
What should I cache dataset or dataview... or what is the best thing to do
in what situation?
Thanks!

Hi,
Is there an easy way , maybe a cast or something to place all of the items
from a datagrid into a dataset.
Sort of the opposite of binding a datatable to a datagrid.
any help is appreciated.

Hi,
i have created a function to open a Databse by OLEDB and fill it into a
System.Data.DataSet-Objekt by oleDBAdapter.Fill-Mehtod..
Now I want to assign this DataSet to a normal Repeater-Control. This
Repeater-Control accepts anything like System.Collections.IEnumerable for a
DataSource.
I have tried to copy the System.Data.Dataset into a DataView-Objekt
(System.Collections.IEnumerable) but I guess there must be some other and

I have a form with a dataset and a datagrid.
I created a dataview on this dataset.
When the user modifies the datagrid, I look up this record in the dataview
to make sure it is unique.
Here is the confusion.........
I thought that the DataView is the view from the dataset, but it seems that
the dataview has the records that are in the datagrid, because everytime I
search for a record that I know is NOT in the dataset, it finds it. I...

Basically I have a DataGrid that I'm binding to the results of a stored
procedure call. The recordset is fairly small. Initially I'm creating a
DataSet from the results and binding it. There's a DropDownList on my page
that filters the records that are displayed in the grid.
How I'm currently handling this is when I initially bind, I create a
DataView from the table in the dataset. When the DropDownList changes
selection, I get the...

I have a code that returns data in IList. My webGrid doesn't allow me to
sort with IList returned, it say it only suports DataView, DataTable and
DataSet, not IEnumerable. I don't know how to return the DataSet type when
using the following code:

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...
