datagrid question for the day....

[Guest]

i have a series of datagrids on a webform. it worked fine until i converted
one column to a template. My guess is i'm blanking on something, but that's
the problem with blanking, ...nothing....
ok now i get a "Expression does not produce a value" error when i run the
project.
What's going on? I know i've done this before...

ok, check it out:

this is what studio put in there:
<asp:TemplateColumn HeaderText="trkSite">
<ItemTemplate>
<asp:Label runat="server" Text='<%# DataBinder.Eval(Container,
"DataItem.trkSite") %>'>
</asp:Label>
</ItemTemplate>

but had to change it to this to get it to work:
<asp:TemplateColumn HeaderText="trkSite">
<ItemTemplate>
<asp:Label runat="server" Text='<%# Container.DataItem("trkSite") %>'>
</asp:Label>
</ItemTemplate>

what's the deal?

i would do
<asp:Label runat="server" Text='<%#
DataBinder.Eval(Container.DataItem,
"trkSite") %>'>

container.dataitem...

thanks for replying and for the code snipit,
my question is why doesn't vs.net convert the item to a template correctly?
