All of the examples I've found regarding custom paging in a GridView that uses the ObjectDataSourc e control retrieve subsets of ALL of whatever it is--all products, all categories, etc--restricted only by specified PageSize. But suppose you are searching for a person by name and the user can enter into a search box any part of last name, first name, middle name, e.g., Adams or Adams M or Adams Michael This input is then a control parameter in addition to the startRowIndex and maximumRows parameters. If the user enters 'Adams', you then want to retrieve x number of records at a time for people named 'Adams'.
I tried putting the logic for parsing the user input both in the Select method and in the SelectCountMeth od. The Select method then passes the parameters to a method in the DAL. At best I am able to retrieve the default first 10 records for people named Adams. The 'Next' button does not retrieve the next batch.
Without looking at my code, can anyone out there give me some guidance on how to work with the control parameter in addition to the startRowIndex and maximumRows parameters or is this not possible with the ObjectDataSourc e control?

I've recently done something similar to you and could not use the ObjectDataSourc e control...mainl y because I had a custom object returning the results from a database in a very customized way.
What I did was use a DataView object as my GridView's DataSource. Paging works fine for me...
I'm not sure this would work with your solution because of how you are doing your searches....but it might be worth looking into.

Hello,
just two sad thoughts on GridView's custom paging support, the first one
rather general and second one rather specific.
First one: I really miss the DataGrid custom paging support with
AllowCustomPaging and VirtualCount. The new declarative model with
ObjectDataSource is much worse! - the amount of "words" you have to type is
comparable (few methods in C# vs declarative binding with ObjectDataSource),
however the static typing...

Hey all,
I must be losing my touch. I have made many pages in the 1.1 framework
that utilize custom bidirectional paging in datagrids. We've converted
over to 2.0 and I've been trying to use the built-in functionality of
gridviews and objectdatasource's to accomplish the same thing (w/o
resorting to the 1.1 methodology). I discovered two very nice and
comprehensive articles concerning this:

Hi!
I'm looking for a solution to show data in a table.
I think about DataView control - but I see one problem.
My data source is a WebService returning paged pieces
of data (I can't change behavior of this data source).
I found in documentation the only way to implement custom
paging is to use ObjectDataSource - but there is different
model of arguments (page size, page number, sort expression ,
order expression) of WS methods - there...

The default paging behavior of the gridview doesn't work well with very large
sets of data which means we have to implement some sort of custom paging.
The examples I have seen (4guysfromrolla, etc.) suggest using an
ObjectDataSource which has built-in paging functionality that, when used in
conjunction with certain SQL 2005 functionality, only works with the records
to be displayed on the page rather than the entire set. The problem with...

Hi,
Could someone point me to source sample C# code to do gridview custom
paging? No ObjectDataSource please, the reason I don't want to use ODS is
the page is already created using the DataSource to do data binding, it will
takes some efforts to convert it to use ODS.
TIA

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

For most users, this new feature is actually very convenient. If you want to control the update process,...
