For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.

Examples

The following code example demonstrates how to use the AutoGenerateFields property to statically associate the fields with their collection in the Details view of an ObjectList control.

Note

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information, see ASP.NET Web Forms Page Code Model.

Remarks

When true, the object list handles the fields order in the ObjectListFieldCollection collection. When false, you must specify the order of the fields and set the DataItem property to bind to a data source.
