I have a datalist that outputs a link to a picture in each ItemTemplate:
e.g.
<asp:DataList id="DataList1" ...etc>
<ItemTemplate >
<a href='Pic.aspx? pic=somenumber' >picture</a>
</ItemTemplate>
<asp:DataList >
What I want to do is set the "pic=somenumber " querystring value
to the current DataList item's index.
e.g. something like:
Pic.aspx?pic=<% =DataList1.Item s.Item.ItemInde x%>
This returns an error.
How can I retrieve the index of the current Item as it's loading the
template?
I could also create my own index value, that increments as the
DataList adds another ItemTemplate.. but not sure how to do this.
Thanks!
Peter

I dont have a development machine in front of me at the
moment, but I do know that a lot of other .net
databindable lists have OnItemDataBound , and OnItemCreated
events.
If it has a OnItemDataBound event, it'd be REAL easy.
throw some winforms control in the template, then you can
modify it from the code behind
if(e.ItemType == ListItemType.Li stItem){
((LinkButton) e.FindControl(" myLinkButton")) .LinkUrl =
e.Item.ItemInde x;
}
Something along those lines. I know it works for DataGrid
and I am pretty sure data list too, but I dont think it
works with repeater. -----Original Message----- I have a datalist that outputs a link to a picture in
each ItemTemplate: e.g. <asp:DataLis t id="DataList1" ...etc> <ItemTemplate > <a href='Pic.aspx? pic=somenumber' >picture</a> </ItemTemplate> <asp:DataLis t>

P.S. Per Weston's comment, I too prefer to do most things of any complexity
in the code-behind. What he suggested will work great.

Two ways:
1. Use '<%# container.itemi ndex %>'
2. Create a public function on the page that bumps and returns a static counter, e.g. (in vb)
Private m_Num As Integer = -1 Public Function NextNum() As Integer m_Num += 1 Return m_Num End Function
then...
'<%# NextNum() %>'
The first is easier, the second more extensible.

When a datalist is rendered to a page and you use the <itemtemplate> the

Most of the time when I use a datalist I utilize the header, item, and

Hello everyone,
I have a composite control (lets call it the parent) that contains a
datalist. The datalist has an ItemTemplate that contains another
composite control (lets call it the child). I am trying to create a
property at the parent control that sets a property in the child
instances.
So for example lets say I am creating a control that displays a list
of hotel reservations for a group of people.
