Deploy the Custom Data Source

To publish a custom data source for use with AgilePoint:

1. Create an assembly with a class that implements the IWebPartDataSource interface. This class should contain your custom logic to get data from external Data Source. The assembly should be strongly named.

   The following specifications describe the interface:

   • Pi ids parameter - Contains all process instance IDs the Web Part will render. This is useful if you want to filter your queries to external data source based on process instance ID. In fact, AgilePoint strongly recommends you use this parameter to optimize the performance, based on this diagram:
   
   • Fields parameter: - An array of NameValues. Contains the fields that are configured for rendering on Web Part results. The name property of NameValue is the internal name of the field, and the value is the display name of the field.
   • Filters parameter - An array of NameValues. Contains the filters for the data source. The Name property of NameValue is the internal name of the field, and the value is the value of the filter.
   • ConfigData parameter - Is an array of NameValues. It contains configuration data for the data source.
   • Return type - You must return a DataTable with your custom data. This DataTable should contain a column named ProcessInstanceID. This column is essential to merge with the main data source.
   • GetRequiredParameters method - This method enables you to specify what parameters are needed to configure the data source. On configuration-time, those parameters will be rendered on Data Source Parameters configuration grid.
2. Deploy the assembly to the GAC.
