This example illustrates how the appointment editing form with multiple resources selection can be implemented in a project with ASPxScheduler control bound to SQL Server.
The CarsXtraScheduling.sql file contains the data table script used to create a sample data table at the SQL server.
To switch the scheduler to multi-resource mode, the Resource Sharing property is set to true. A custom appointment editing form is implemented and the appointment field mapping for the ResourceIds property is specified.
Note: starting from the v2009 vol.2 release the standard appointment form contains an ASPxListBox control which provides the required functionality for assigning multiple resources.
For ASPxScheduler releases prior 9.2, the following workaround is used.
A custom appointment editing form contains a data-bound control with multiple selection capability. The control is based on a combination of ASPxCheckBox and ASPxHiddenField controls, enclosed into a Repeater control template.
