If i have a node with documenttype alias as "entry", which is created as a child node to many different root and child pages, is there a way to get the total count on created "entry" type nodes and display in razor view in Umbraco?
Yes, of course, for v7 use:
Model.Content.Site().Descendants("entry").Count()
for v8
@Model.Root().DescendantsOfType("entry").Count()
