Conditional rendering of an image
<% if (Container.CurrentPage.IsValue("MyImageProperty") { %>
<img src="<%# Container.CurrentPage["MyImageProperty"] %>" />
<% } %>
IsValue is just an extension method that you can pull from EPiCode.Extensions.

Unfortunately that doesn't work. Visual Studio doesn't understand what Container is in the if statement (but it does in the img tag).
Any idea why?

How about: <img src="<%# Container.CurrentPage["MyImageProperty"] %>" runat="server" visible="<%# Container.CurrentPage.IsValue("MyImageProperty")" />

I'm not sure what visible is supposed to do, but setting visible="false" still displays the image. I can use "display: none" in this way though:
<img src="<%# Container.CurrentPage["MyImageProperty"] %>" runat="server" style="display: <%# Container.CurrentPage.IsValue["MyImageProperty"] ? "none" : "block" %>;" />
The problem is that the img-tag is still rendered. I don't want that. Isn't there a simple way to only render the tag (in a repeater) if some condition is met? I cannot be the only guy with this problem.

Fredriks example should work, but you could always wrap it with a placeholder:
<asp:placeholder visible='<%# Container.CurrentPage["MyImageProperty"] != null %>' runat="server">
<img src... />
</asp:placeholder>

The PlaceHolder control is exactly what I'm looking for. I wasn't aware of its existance, so thanks a lot for enlightening me!

Hi all!
I have a page property of type PropertyImageUrl. To render it I tried to use <EPiServer:Property PropertyName="MyImageProperty" runat="server" />, but that rendered an a-tag and not an img-tag. So instead I used <img src="<%# Container.CurrentPage["MyImageProperty"] %>" /> (in the ItemTemplate of a PageList) to render the image.
My problem now is that when MyImageProperty is not set, I dont want to render an img-tag at all. Not with an empty src attribute and not with a fallback image.
What is the recommended way to accomplish this?
Thank!
