NET Developer's Cookbook Sample Chapters Book Reviews Community Regular Expressions In this article the author presents a comprehensive solution to build a Grid View with template fields generated at run time with in-place Insert, Delete and Edit operations with a full description of an effective implementation and usage of ITemplate interface.
Generally, a template is description of how a particular item will be rendered at run time. At design time we can define templates declaratively using inline tags in aspx source of Grid View (the following listing shows this).
We need to generate Item Template and Edit Item Template dynamically for each field of the table, plus a field for buttons required for each command.
This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.
It shows that we must know number of fields and their name in advance to create their templates. Listing 1 keeps an indicator in string form for a type of information within a template field i.e.
whether a template field has information of "Command" or "String" so that later data retrieval and data binding of that particular child control will be made accordingly.
Although just binding the Grid View with some dynamically changing datatsource is a simple and straight job which does not need templated Grid View, it cannot facilitate us with the aforementioned operations.
