How can I replace a single backslash with a double backslash in my Kend.UI grid? Mvc.Net app with C#.Net code-behind

I have an MVC.Net application with C#.Net codebehind.

In one of my views I use a Telerik.UI grid.  I need help using the Replace function in the grid's template.
I want to Replace the backslash in the FileName value, with a Double backslash (something like this:    #=Filename.Replace('\','\\')  

How can I do this?  in my code below:

                        {
                            field: "HIPBatchID",
                            title: "EDI Portal Batch ID",
                            template: "&nbsp;<input type='button' value='#=kendo.toString(HIPBatchID)#' class='RoundCorner' onclick='getErrorLogByBatchID(\"#=HIPBatchID#\",\"#=Filename#\")' style='width: 90px;border:0; background-color:white; color:darkblue;' />",
                        },

Thank you in advance,
