XPath if statement and GridView <ItemTemplate > Problem

[Opa]

Hi,

I have and XMLDataSource which I am using in a GridView control and am
customizing the grid with <ItemTemplate >. My XML datasource has an element
with an attribute called "private". I want to check the value of the
private attribute
and if is is true, I DON'T want to display this row of data. I am having
trouble with the XPath expression. How is this done?

Here is a sample XML source

<?xml version="1.0"?> <comments><comm ent from="Mike Smith"
private="false" >comment 1</comment><commen t from="Joe Doe"
private="true"> comment 2</comment></comments>

Here is snippet of my page source

<asp:GridView ID="GridView1" ........
<Columns>
<asp:TemplateFi eld>
<ItemTemplate >
<b>From: <%# XPath("./@from") %></b><br/>
Date: <%# XPath("./@date") %><br/>
Private: <%# XPath("./@private") %><br/ ??? How can I use
If here
<%# XPath(".") %><br />
</ItemTemplate>
</asp:TemplateFie ld>
</Columns>
</asp:GridView>
Any Suggestions? Thanks.

You can use an XSLT transform on your data IIRC. Create an xsl
stylesheet that outputs copies of all the nodes where private is not
true and use that as the xsl for the XmlDataSource.

Hi,

I don't want to use an xsl stylesheet. Instead I want and should be able to
do directly in my aspx source. Any ideas on how I can do this from within
<ItemTemplate >

I still can't find an answer to this. Some feedback would be great.
