.NET Standard 2.x
Exports entity class data(DataWindowChild
) from the specified buffer of the DataStore in the specified DataFormat
.
Namespace: DWNet.Data

Parameters
primaryData
System.Boolean
A boolean
specifying whether to export the data from the primary buffer.
True: to export.
False: not to export.
filterData
System.Boolean
A boolean
specifying whether to export the data from the filter buffer.

deleteData
System.Boolean
A boolean

Examples
The following code example demonstrates how to export the course records (including DataWindowChild
) to JSON strings. The "d_course" DataStore has a departmentid column which embeds a child DataWindow "dddw_deparment". When primaryData
is true
, exports data from the primary buffer to the JSON string; when filterData
is true
, exports data from the filter buffer to the JSON string; when deleteData
is true
, exports data from the delete buffer to the JSON string; when dwcdata
is true
, exports data from the DataWindowChild
to the JSON string.
