I'm building Sitecore sheer UI application. The main layout is aspx
page NOT XAML, which contains a grid. I added a dropdown list as a ribbon button. When dropdown list changes, it must filter the grid source based on the selected value in dropdown.
When dropdown list changes, my custom command will trigger, but in the command I can't access my grid control so that I can do a filter. So my question is how can I call a method inside my aspx
page from command class?
