Datalist and template

[MarkusJ_NZ]

Hi, I have a datalist that is used in conjunction to display values
retrieved from a database:

What I would like to do is check the value of a field and then do something
(Change a label or whatever).
Below is my code

' Create a datalist 
<asp:DataList id="MyList" RepeatColumns="2" runat="server">
         <ItemTemplate>
          <table border="0" width="272">
           <tr>
            <td width="25">
             &nbsp
            </td>
' I would like to check the value of the following item and then do
' something if the item is less than 0 
' e.g  if DataBinder.Eval(Container.DataItem, "UnitCost", "{0:c}") < 0
' then response.write("hi") 
             <span class="ProductListItem">
              <%# DataBinder.Eval(Container.DataItem, "UnitCost", "{0:c}")
%>
             </span>

Any help appreciated

Cheers
Mark

you could put a Label in the ItemTemplate, fill it with your initial unchecked value:

<asp:Label Runat="server" ID="lblUnitCost" Text='<%# Container.DataItem("UnitPrice") %>' Visible="False" />

Then loop through all your Items in the Datalist, and then check the value in the label... then do something with it then depending on what you need to do I don't think you can have Conditional statements in the ItemTemplate... :/ i could be wrong though, but i seem to remember trying to do something similar, and it wouldn't let me use an If Then Statement....

Hi, I have found a way to do it using a function. Apparantly you can call a function but not a subroutine from inside a template.
