The ListView control is similar to the GridView control in many ways: both display a set of records, both support built-in sorting,
paging, editing, and deleting functionality with minimal effort. The ListView differs from the GridView in two key ways:
- Rather than using fields, the ListView is rendered via templates, which offers the page developer much finer control
over the emitted markup, and
- The ListView supports built-in inserting support
The first installment in this series explored the ListView's
template-based rendering. This installment looks at how to use the ListView's inserting functionality.
In a nutshell, inserting data from the ListView requires two steps: defining the inserting interface via the InsertItemTemplate
and specifying where the inserting interface should go via the InsertItemPosition property. Much like with
editing data from within the ListView, the
InsertItemTemplate can contain two-way databinding statements when using a data source control to get the inputs entered
by the user from the ListView's inserting interface into the parameters of the data source control. And like with the editing and
deleting workflows, you can programmatically examine and modify the user's submitted data before inserting the data, cancelling the
operation altogether if needed.
This article walks through the steps for creating a ListView that allows users to insert records. It also shows how to optionally
cancel the inserting workflow based on programmatic logic. Read on to learn more!
(It is assumed that the reader is familiar with how to insert data using a data source control. If this
is not the case, please first read Accessing and Updating Data in ASP.NET:
Inserting Data.)
