Our designer had created a comprehensive custom theme for ExtJs, and we wanted to use it in our ASP.NET app that leverages Ext.Net and ExtJs extensively.
If you have used Ext.Net, you would know that all ExtJs resources are embedded in Ext.Net.dll assembly that are automatically put on the page whenever you add an <ext:ResourceManager /> to the page. This includes the core ExtJs css and javascript resources (including current ExtJs theme's resources), plus Ext.Net's own resources (providing extensions/enhancements to Ext classes).
