I have this section defined in my _Layout.cshtml
@RenderSection(\"Scripts\", false)
I can easily use it from a view:
Well, I guess the other posters have provided you with a means to directly include an @section within your partial (by using 3rd party html helpers).
But, I reckon that, if your script is tightly coupled to your partial, just put your javascript directly inside an inline tag within your partial and be done with it (just be careful of script duplication if you intend on using the partial more than once in a single view);
