Eval doesn't work

Mateusz Żebrowski asked on June 22, 2014 17:11

Ok I've got problem with Eval function in document type transformation. I created document Type called "Poem". After that I added three custom fields - I mean I clicked on green plus button titled "Add Attribute" in "Fields". Those fields are "Author" "Title" and "Text". And then wrote the transformation as follow:

    <p>Poem written by <%# Eval("Author") %> titled <%# Eval("Title") %></p>
    <a href="<%# GetDocumentUrl() %>"> Read it NOW!!!</a>

Then I created page with document data source and basic repeater, add under it two poems and all I get is:

Poem written by titled

Read it NOW!!!

Poem written by titled

Read it NOW!!!

The links are good (I'm sure) but I can't see Author and Title. What's wrong?

Hello Mateusz,

Are you sure you use ASCX transformation? The thing is Eval method can only be used in this type of transformation.

In case of Text / XML transformations, you can use e.g. {% Author %} directly.

Also, are those fields standard Text boxes or have you used any other form control?

I'm Sure this is ASCX transformation. Author and Title are standard text boxes and I didn't used my own form controls (what if I were?). If my problem description is not clear I can write what I did step by step. It's strange for me too.

Check the event log for more details. Are you sure the field name is "Author" or "Title"? You have to use the actual column/field name and not the caption. Also, what types of fields are they (int, text, etc.) and what is the control you're using for each field (textbox, WYSIWYG editor, etc.)?
