Similar to field templates, Dynamic Data uses the last part of the template file name to
determine its mode. For the Customer page, you might need to have the following three
templates in the
DynamicData\EntityTemplates
folder of the web application:
.
Customers.ascx
, the read-only template
.
Customers_Edit.ascx
, the edit template
.
Customers_Insert.ascx
, the insert template
Creating the
Customers_Edit
and
Customers_Insert
entity templates is straightforward;
they are nearly identical to the Read-only
Customers
template (see Listing 4.3) except that
the
Mode
property of the
DynamicControl
instances is set to
Edit
and
Insert
respectively.
Listing 4.14 shows the Edit mode template for the Customer entity.
