asp.net datagrid control: Hello,

I'm loading a datagrid from an XML file. I'm using datagrids edit
functionality and its working great. My problem is that this list is 667
records. When I press Edit the page reloads and starts at the top. Then I
have to scroll all the way down to get back to the item I'm editing. I guess
I have one of two questions that needs answering:

1) Can I page through XML? If So, How?

2) Is there a way to possibly use anchors so that the page refreshes and
moves to the record I am working with?

Thanks a ton!!!

Hi David,

Hi Welcome to ASPNET newsgroup.
Regarding on the questions you mentioned, here are some of my suggestions:

1) Can I page through XML? If So, How?
===================================
For paging , since you're not using the ADO.NET data components (DataSet,
DataTable..), I think you'd use the custom paging of the asp.net datagrid.
What we need to do is register the Paging event for datagrid and then bind
the certain page's data items to the datagrid in the Paging event handler.
here are some msdn reference on this:

#Specifying Paging Behavior in a DataGrid Web Server Control
http://msdn.microsoft.com/library/en-us/vbcon/html/vbtskSpecifyingPagingBeha
viorInDataGridWebControl.asp?frame=true

#Walkthrough: Creating Paged Data Access Using a Web Forms Page
http://msdn.microsoft.com/library/en-us/vbcon/html/vbwlkwalkthroughdisplayin
gdatainlistboxesonwebformspage.asp?frame=true


2) Is there a way to possibly use anchors so that the page refreshes and
moves to the record I am working with?
=======================================
For keeping page's focus on the current editing item (or selecting
item...). We have the following two options:

a) register a simple clientscript code whch use the html element's focus()
method to set focus on the current item when the page has been loaded at
clientside( Page.RegisterStartupScript...). However, in this case we need
to have a certain identified control in our template column so that we can
use that control to set the focus.

e.g:
we have the following template column:
=======================
<asp:TemplateColumn>
<ItemTemplate>
<asp:TextBox ID="txtFocus" Runat="server" Width="1"
Height="1"></asp:TextBox>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtFocus" Runat="server" Width="1"
Height="1"></asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>
======================

we can use the following code in ItemCommand to set the focus:
==========================
private void DataGrid1_EditCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
DataGrid1.EditItemIndex = e.Item.ItemIndex;
DataGrid1.DataSource = GetDataSource();
DataGrid1.DataBind();

Control ctrl = e.Item.FindControl("txtFocus");
string script = @"<script language='javascript'>
document.getElementById('{0}').focus();
</script>";


Page.RegisterStartupScript("page_set_focus",string.Format(script,ctrl.Client
ID));
}
========================


b) We can turn on smartNavigation on the page we need to keep focus between
postback

IMO, I prefer the a) since it's more lightweight( smartnavigation will
somewhat impact performance )

Hope helps. Thanks,
