Datagrid and paging

Hello Masters!

Anyone can help me with the datagrid,
well, the app load a lot of data from DB and it show on the datagrid, and
well,
I need to allow paging and.... the issue is with the event PageIndexChange d
of the datagrid 'coz every time when the user change of page the app load
again all data and another processes with the data even though I have load
one dataset with the data for the datagrid..... the question is?
What can I do to link the datagrid with the dataset on the event?

Thanks a lot in advanced.

You probably can cache the Dataset and just work with an in-memory copy.
When you need to use the dataset then cast it back out of the cache object.
I just hope I am understanding your question. Did this give you any help?

Well it fires both events. So if you put your code to load the dataset into
the Grid in the Page_Load, then yeah, you will be doing it twice. Just make
sure in your page load you load the datagrid once by doing this:

if(!IsPostBack)
{
// do this ONLY the first time the page loads
}
else
{
// do this on all other postback request to this same page
}

Then you are free to load the dataset and bind the datagrid in the
PageIndexChange d. I think this answers your question, but if I didn't a
least I tried! :)

I can not get my datagrid to page. I have a datagrid that I can sort 2 of the columns. This works great. I added paging and when I display the dg it shows 5 pages. (I am showing page numbers at the bottom of the dg.) When I click on the pages nothing happens until I get to the last page. Then and only then is the last page displayed. If I go back through the pages the second to last page displayes the first page again.

Hi Sorry for posting again. I have a datagrid which is put inside a div tag to make it scrollable. I need to page the datagrid. The page numbers appear at the bottom of the datagrid and has to be scrolled down completely to see the page number links. The page number should always be visible outside the scroll bar. Basically I want to create the paging links dynamically and on click of this it should fire PageIndexChanged event.

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...

Hi- I have a datagrid that in some cases can be several thousand rows in length. What I'd like it to do is have the data pushed to the browser after every, say, 100 rows or so. Kind of a "response.flush" effect-- at a certain recurring point in the process, take what we've got and send it to the browser. Is this possible? Thanks.

Hi, I'm using a DataGrid control to show a table's content with paging. For navigation through the pages I'm using the DataGrid's intrinsic navigation section. My problem: The DataGrid navigation links use JavaScript to jump between pages. I want them to use standard hyperlinks providing the page number in some URL parameter so that I can copy the hyperlink elsewhere.

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,
