DataStoreDataExtensions.ExportPlainXml(this IDataStoreBase dataStore, bool primaryData, bool filterData, bool deleteData, bool dwcdata) Method

.NET Standard 2.x

Exports data from the specified buffer(s) and/or DataWindowChild to a plain-format XML string.

Namespace: DWNet.Data

Assembly: DWNet.Data.dll

Syntax

  public static string ExportPlainXml(this IDataStoreBase dataStore, bool primaryData, bool filterData, bool deleteData, bool dwcdata);

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.

True: to export;

False: not to export.

deleteData System.Boolean

A boolean specifying whether to export the data from the delete buffer.

True: to export;

False: not to export.

dwcdata System.Boolean

Aboolean specifying whether to export the DataWindowChild data.

True: to export.

False: not to export.

Returns

System.String

Returns the XML string if it succeeds.

Examples

The following code example demonstrates how to export the course records (including DataWindowChild) to XML 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 XML string; when filterData is true, exports data from the filter buffer to the XML string; when deleteData is true, exports data from the delete buffer to the XML string; when dwcdata is true, exports data from the DataWindowChild to the XML string.
