Interferences (custom JavaScript, CSS, third party controls)

DayPilot renders partially on the client side (it uses JavaScript to modify the DOM tree). Both the resulting DOM tree and supporting JavaScript code are complex and it may happen that it will interfere with the rest of your code, especially:

  • style sheets (CSS)
  • third party ASP.NET controls (especially when you place DayPilot inside a third party container)
  • custom JavaScript

Sometimes it can be fixed inside DayPilot (especially the CSS) but sometimes not (third part ASP.NET controls). Please contact to check the options.
