Modify Kentico listing view

Question

Is there a way to modify the listing screen in Kentico's tree view?

Basically, my requirements are as follows

1.Set the default 'Page type' for a specific page type (Not a global change, just for specific page types)

2.Remove 'Show all levels' tick box

Answer 1

I would try creating an extender for that UI page. Or, you can still customize the physical code file and adjust the UniGrid logic:

CMSModules/Content/CMSDesk/View/listing.aspx

which uses this control

~/CMSModules/Content/Controls/DocumentList.ascx which uses the UniGrid.
