    Hi All

    In my application we are using backbone.js for MV* type functionality.  IT performs navigation events based on hash (#) in a URL.  So for example entering in #profile brings up your profile.  We are using a KendoUI template in a grid (since I couldn't get other templates to work right).  Is there anyway to escape a # that may appear in the template?

    Hi John,

    The getting started / templates article in our documentation describes the escaping syntax in strings and script templates in details.

    Hi Petyo,

    I believe in my case I was using a literal string.  How do I escape it when using a literal string (#= .. # format)

    Hello,

    Unless I am missing something, I don't think you need any sort of a special treatment for the strings in the template (escaping # symbols, etc). If you still experience troubles with this, can you prepare a small example? We will check it out and do our best to help. 

    All the best,

    Yes, it's very easy to reproduce.  Here you go: http://jsbin.com/ivivac/1/

    Hello John,

     This is not a valid template. The #= # expression should contain a valid JavaScript identifier which "#" by itself isn't. Here is the updated demo with a valid template and values containing "#": http://jsbin.com/ivivac/5/edit

    Here's an updated version that's closer to what we're trying to do.

    http://jsbin.com/ivivac/6/

    Basically, we want # to appear in front of the value in the model of the datasource.

    Hello John,

     In that case you just need to put the # outside of the #= # expression:

      rowTemplate:kendo.template("<tr><td>\\# #= value #</tr>"),

    Here is the updated example: http://jsbin.com/ivivac/7/edit

    But then # is outside of the literal expression, going back to my prior post; "There is no way to put a # in a literal expression."

    Hello John,

     I provided a working version of the demo. Did you check it out? It shows how to escape a "#" in a template definition. And yes, you cannot have "#" inside a "#= #" expression.
