Hi Everyone,
I am trying to implement a DataGrid that uses Custom paging, but the DataSource is a SQLDataReader, not a DataSet. I have seen examples that use the Fill method of a DataAdapter to only retrieve a page of data, eg:
daCustomers.Fil l(dsCustomers, (PageNum - 1) * intPageSize, intPageSize, "Customers" )
But I am having difficulties achieving this using a DataReader. My goal is to have a datagrid that only displays 10 rows of data at a time and allows the user to move between pages as well as allowing the user to sort the data - all without using a DataSet (not for any particular reason - I just want to do it this way)!
Cheers,
Paul

You are attempting to use a DataReader in a way for which it is not intended. DataReaders are for one time forward only reading of data out of a database. You can't "page" a DataReader because you can't go backwards.
Stick to the DataSet or a DataView based on a DataTable.

Hi Guys,

But after adding Paging IT WON'T PAGE!!
It compiles well but when i click on the paging link it doesn't go to the

"AllowCustomPaging must be true and VirtualItemCount must be set for a
DataGrid with ID MenuGrid when AllowPaging is set to true and the selected
datasource does not implement ICollection"

Hi.
I already have a datagrid where I'm using paging. I have a stored procedure
that fills a temp table with 200-500 rows and then sends back 10 records at
the time. When I go to page 2 the SP fills the temp table again and returns
rows 10-19. The temp table is dropped after each call to the SP, so it has
to be created and filled every time the user changes page in the datagrid.
My question is this: Would it be more efficient to...

Is there a way to carry data that I have already read from the datagrid from
page to page?
I am looking at my Datagrid that I page through and when the user says get
the next page, I have to go to the database to get the next page. Is there
a way to use the dataset to allow us to read back and forth in it instead of
going back to the database to get it?
Thanks,

Hi all,
Can somebody tell me if the built in paging support for the datagrid works
when using a custom collection and a custom business object as the data.
I was well pleased when I found that I could bind a custom class to the datagrid.
Now however, I'm worried that paging is buggered because I'm using custom
classes.
Should this be possible and if not, would custom paging work?

Dear Groups
I've used paging with a datagrid in C# at least a hundred times, but
for whatever reason, I cannot get the prev /next to appear as links.
It is absolutely certain that the number of records exceed the page
size.
Code is as follows:

I have a DataGrid that I'm adding CheckBox controls to at runtime (in

First of all, I noticed that the MyDataGrid.Columns.Add() method expects
