Edit and Insert Entity Templates

In addition to the Read-only entity templates that have been discussed so far, Dynamic
Data also supports entity templates in Edit and Insert modes. Consider the FormView
control in Listing 4.13, which in addition to the Read-only ItemTemplate used earlier also
defines the EditItemTemplate and InsertItemTemplate sections. All three of these
sections use the DynamicEntity control to load an appropriate entity template dynami-
cally, based on the MetaTable associated with the FormView and the Mode property, which
can be Insert , Edit , or ReadOnly (default).
