Nevermind. I found the issue. I had previously added a link to jquery 3.5.x in a _Layout.cshtml file (asp.net) and had forgotten about it. For testing the jqx widgets, I added another link to jquery in a another view (which used _Layout.cshtml as it “base” file) and right before the jqx widget links. As part of the asp.net pipeline, the dependent file’s info is parsed first (along with its javascript links), then the “_Layout” file (along with its javascript links). Since the jqx bindings to jQuery were occurring in the dependent file, once the “_Layout” file was parsed, it’s jQuery link overwrote any plugin additions (i.e., erasing any previous jqx bindings).
