How do I combine a string with a variable in Bind() in an .aspx file for a DataList?

Question

I've searched for this, but maybe I'm using the wrong keywords.

I have a DataList containing an ImageButton whose ImageUrl property I want to set by combining it with a string returned from a codebehind file property and a database value.

I have a protected property in my codebehind called strPath.

I want to combine it with a database value in my aspx file. Like so:

... ImgUrl = '<%#strPath+ Bind("senderPic")%>' ...

But this doesn't work. How can I do this?

EDIT:

HEre's the entire code for the DataList as asked. (The problem is in the ibtnUser element.

Try to use

ImageUrl='<%# ThePath + DataBinder.Eval(Container.DataItem, "picName") %>'
