Inline Code Problem

Is there a reason you can't use an <asp:Image> tag and do the processing in the code-behind?

What error message are you getting from this code?



valkyrie_nc

well it populates the repeater, and it says we cannot use the eval function in that respect. How would we do this using the asp image

Thanks

Andy

Oh wait , I think I see what's going on.  You're binding data to the repeater, right?  If so, you need to use the DataBinder object instead of Eval to assign values:

<% DataBinder.Eval(Container.DataItem, "prod_image") %> instead of <%#Eval("prod_image")%>

You can also use your ItemDataBound event to assign the appropriate values & such to the controls in your Repeater.  

Let me know if I just went way off into left field.

no no you are right. But I need the code inline, or taught how to in code behind. Here is the lat error I got with your code

Compiler Error Message: CS0103: The name 'Container' does not exist in the current context

Source Error:

 

Line 25:
Line 26:             <%
Line 27:         if (DataBinder.Eval(Container.DataItem, "prod_image")  =="CONFIRMED")
Line 28:         {
Line 29:             %>
 


here is my repeater.


<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
            <div class="ProductBox">
                <div class="Prod_Image">

        if (DataBinder.Eval(Container.DataItem, "prod_image")  =="CONFIRMED")
        {

                <img src="product_images/Medium_<%#Eval("prod_id")%>.jpg" alt='<%#Eval("prod_name") %>' />
            <%
            }
            else
            {
            %>

                    <%#String.Format("{0:£ ##.00}",Eval("unit_price")) %>
                </div>
                <div class="more">
                       <a href="ProductDetail.aspx?prod_id=<%#Eval("prod_id") %>" class="more"><img src="images/More_Button.jpg" alt="More Details About <%#Eval("prod_name") %>"</a>
                </div>
           
            </div>
    </ItemTemplate>
    </asp:Repeater>

How are you binding data to the repeater?  Can you post that code?

}

all i want to say is if prod_name for each data item is "CONFIRMED" then show an image else show a default image

Okay, the DataItem.Container broke because you're not using named columns in your querystring but are just pulling them all; that threw me.  I looked back over everything and think I see a quick 'n' dirty way to fix the problem.

<script language='javascript' type='text/javascript'>
   if (<%#Eval("prod_image")%> == "CONFIRMED")
   {
      document.write('<img src=\'product_images/Medium_<%#Eval("prod_id")%>.jpg\' alt=\'<%#Eval("prod_name") %>\' />');
   }
   else
   {
      document.write('<img src="product_images/test_product.jpg" alt=\'<%#Eval("prod_name") %>\'/>');
   }
</script>

Sorry to make you post so much; guess it took the ol' gray matter a while to clear up.  :)
