At the moment, it is not included.
There are two versions of Calendar Panel. One that existed in Ext.NET
for a long long time (since version 1, here
), exclusive to Ext.NET, and another from Sencha
. Sencha one was introduced around September 2016
as a separate licensed subproduct and our licensing terms didn't allow merging it even to older 5.x versions.
With Ext.NET 7 though, the opportunities opened with Sencha, so we may be able to legally merge it in future releases of 7.x (and even maybe 5.x!), so when we are able to include UX components in 7, there are good chances the Calendar Panel will be part of it. Depending on features and stability we may (or may not!) say goodbye to old Calendar Panel.
Currently Ext.NET 7 client-side code employs Ext JS 7.3.1 commercial license product with no further-licensed Sencha components
*) from the link, Ext.NET includes not every PRO entry, but the Ext JS framework. The items still not included in ExtJS regarding frameworks are the component entries there, like Calendar, Pivot Grid, D3, and so on.
Hope this helps!
