I have a simple DataGrid and trying to get paging to work. I
orginially want to use this in an AJAX UpdatePanel, but I moved it out
of it until I get it to work.
This is the DataGrid in the ASPX:
<asp:DataGrid ID="dgActiveVis its" AutoGenerateCol umns="true"
AllowPaging="tr ue" PageSize="5" Width="100%" BorderWidth="0"
CellPadding="3" CellSpacing="0"
OnPageIndexChan ged="dgActiveVi sits_PageIndexC hanged" runat="server">
<HeaderStyle BackColor="Gray "
ForeColor="Whit e" />
</asp:DataGrid>
The C# code behind:
protected void Page_Load(objec t sender, EventArgs e)
{
if (!Page.IsPostBa ck)
{
dgActiveVisits. CurrentPageInde x = 0;
BindData();
}
}
protected void dgActiveVisits_ PageIndexChange d(object sender,
DataGridPageCha ngedEventArgs e)
{
dgActiveVisits. CurrentPageInde x = e.NewPageIndex;
BindData();
}
void BindData()
{
DataTable dt = new DataTable();
// removed DataTable setup, has 15 rows
dgActiveVisits. DataSource = dt;
dgActiveVisits. DataBind();
}
When the page first loads, it loads the first page of data just fine.
But when I click Next, the entire DataGrid just disappears... At first
I thought there was an issue with the UpdatePanel, but after taking it
out of the UpdatePanel it still displays this same behavior... I
looked all over the internet and followed their examples exactly...
Any help would be greatly appreciated... 7 4252
Try using the PageIndexChangi ng event instead.

There isn't a PageIndexChangi ng event, not in VS IDE, anyway.
Brad
Also, you'll notice on the Page_Load it sets the current index to 0.
If I change that to 1 or 2, it does display the appropriate page of
data on first load. But again, moving back or next causes the entire
DataGrid to disappear...
The only thing I'm doing differently from previous apps, is I have
added the AJAX extensions to the web.config and I've installed SP1 for
VS 2005.
I can not, for the life of me, see the problem. Any help is much
appreciated...

So I copied paste the code into a new Web Form and, of course, it

The Datagrid populates fine. I'm styling it on the HTML page. I
configure the DataGrid for paging through the property builder fine.
I AllowCustomePaging=true;. The page loads fine but it only shows "1"

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'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,

I have 3 Datagrid nested.
Master
Details
Child
The master has paging (And i'm using the paging inbuilt in the Datagrid)
in the Master DataGrid you select a linkbutton(using commandname) and it
populates the data in the Details DataGrid
(I'm using Dim Filter As String =
CStr(dtgMaster.DataKeys(dtgMaster.SelectedIndex)).Replace("'", "''") to
filter btw the Datagrids)
