Remarks

Use the DataField property to specify the data field to bind to the DynamicControl control. The data field can be the column name or, for foreign key columns, the relationship name.

By default, the specified data field is displayed by the DynamicControl control using the field template that is associated with the field data type. You can change the field template that is rendered for the data field by setting the UIHint property. You can also format the displayed text by setting the DataFormatString property.

Note If you want to change the display and behavior of a data field globally, you must apply attributes to your data model instead of setting this in a particular instance of the DynamicControl control. For more information, see ASP.NET Dynamic Data.
