Forms Data Controls :: Repeater ItemTemplate - If Eval(field)=0 Then HTML Else HTML

Feb 20, 2010

The following seems reasonable, but it returns an error:

<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........

Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.

Forms Data Controls :: Using Custom Text Before Eval?

Mar 4, 2011

I have a repeater that has been given a datasource from my database containing pictures. The problem is that when i create and log a user into my site i send him to a folder that has no access from others than the ones with a roles called User. When he creates his profile, he uploads a picture which is saved in the same folder "User/picture/picturename" and in the database "picture/picturename".

Now i need to pull this picture to the Default page page where users are not logged in. If i add an Image Control to the frontpage with ImageUrl='<%#Eval ("PictureThumbURL") %>' it tries to pull out the picture from the folder User which is obvious that it can't since it lacks the User/ in front.

Is it possible to get this picture by manually adding User/ to the ImageUrl='<%#Eval ("PictureThumbURL") %>' and if so, how?
