| 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,
|

| | 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!!!
