Thread: replace \

The problem is that the original string only has a single \ so I don't think the double \\ in the replace is found.

OK. I think I've found the problem.

I was registering the clientscript inside a if not ispostback section, so when I uploaded a document it was posting back and the clientscript wasn't registering on postback.

Even though when I view the source I see a reference to the .js file. I moved it outside the if not ispostback and the error has stopped.

I had already altered the script to use a double slash (\\) in my code, but am going to change this back to see if it will work without the double slash.

Yep. That was the problem.

It works fine with just single slashes. It was registering the clientscript that was the issue.
