ASP.NET ComboBox - Populating with Data - ObjectDataSource

The ComboBox can be populated from various types of data sources:

DataSourceControls - SqlDataSource, ObjectDataSource, LinqDataSource etc.;
LINQ - LINQ queries at runtime;
Collections (generic & non-generic) - IList, IEnumerable, etc.;
DataSet / DataTable;
Declarative

The ComboBox presented in this sample is populated from a ObjectDataSource control. This is done by setting the DataSourceID property of the ComboBox to be the ID of the ObjectDataSource control.

Also, the DataValueField and DataTextField properties need to be used to specify the name of the database fields that will be used to populate the Value and Text properties of the generated ComboBoxItems.

"I just want to say that your response time is incredible... the developer we have working with the license we purchased (Grid) has reported that he is getting technical support responses in under an hour consistently (and they make sense and solve his problems). GREAT company! I will be telling others about our experience."
