Hello,
I am just trying out reading an XML file in an ASP.NET page, but am
having a little trouble. I'm sure this is something really obvious and
dumb, but I can't see what ...
I have an XML file that contains some site map info (see further down),
and I have written a page to read this in and display the contents. I
put it into a datagrid and also use a repeater (the former was a quick
way of seeing what happened, the latter was in an attempt to have more
flexibility over what I do with the data).
The grid shows the five items in the XML file, but the repeater only
shows three. If you look at the source generated, it seems that the
other two entries are blank.
Anyone any idea why? Any help appreciated.
First the ASP.NET file ...
<%@ Page Language="C#" Debug="true" %>
<%@ import Namespace="Syst em.Data" %>
<script runat="server">
void Page_Load(Objec t sender, EventArgs e) {
DataSet dstXML;
dstXML = new DataSet();
dstXML.ReadXml( MapPath("SiteMa p.xml"));
// display the info in a repeater
rptSiteMap.Data Source = dstXML;
rptSiteMap.Data Bind();
// display the info in a grid
dgrdData.DataSo urce = dstXML;
dgrdData.DataBi nd();
}
void rptSiteMap_Item (Object sender, RepeaterItemEve ntArgs e) {
if (e.Item.ItemTyp e == ListItemType.It em) {
Literal litLink = (Literal)e.Item .FindControl("l itLink");
litLink.Text = (string)DataBin der.Eval(e.Item .DataItem, "Title") + "
<small>(" + (string)DataBin der.Eval(e.Item .DataItem, "URL") +
")</small>";
}
}
</script>
<html>
<head>
<style type="text/css">
body, p, td, h1, h2, h3 {
font-family: Arial;
color: #0000ff;
background-color: #ffffff;
}
</style>
</head>
<body>
<form runat="server">
<p><asp:Repeate r id="rptSiteMap " OnItemDataBound ="rptSiteMap_It em"
Runat="Server">
<ItemTemplate>< br><asp:Literal id="litLink" Runat="Server"
/></ItemTemplate>
</asp:Repeater></p>
<hr><br>
<asp:DataGrid id="dgrdData" Runat="Server" />
</form>
</body>
</html>
Now the XML file ...

and finally the HTML sent to the browser (for clarity, I've only posted
the relevant bits and ignored the view state info, etc) ...
