问题 Does anyone know how to pass html attributes like "data-date" to the Html.TextBox()?? It is used from the bootstrap datepicker.

I then closed and reopened Visual Studio, but my editor isn't showing the desired syntax highlighting. I can copy and paste the contents of file1.cshtml into file2.json and everything looks ok, but I'd rather not have to do it this way. I'm using

问题 I created an extension method based on this answer to the SO question c# - How can I create a Html Helper like Html.BeginForm - Stack Overflow and it works fine. Can I move the embedded HTML in the extension method into a partial view and use that partial view in the method while preserving it's current behavior?
