    DataStoreDataExtensions.ExportPlainXml(this IDataStoreBase dataStore, DwBuffer dwbuffer, bool changedOnly) Method

    .NET Standard 2.x

    Exports all rows or only the changed rows from all or specified buffers to a plain-format XML string.

    Namespace: DWNet.Data

    Assembly: DWNet.Data.dll

    Syntax

      public static string ExportPlainXml(this IDataStoreBase dataStore, DwBuffer dwbuffer, bool changedOnly);
    

    Parameters

    dwbuffer DWNet.Data.DwBuffer

    A value of the DwBuffer enumerated datatype identifying the DataWindow buffer from which you want to export the data. For a list of valid values, see DWBuffer. If not specified, all of the DataWindow buffers will be exported, however, the data for DataWindowChild will not be exported (even if changedonly is false).

    changedOnly System.Boolean

    A Boolean specifying the changing flag.

    True -- to export the changed rows only (and all rows of the delete buffer).

    False (default) -- to export all rows.

    Returns

    System.String

    Returns the XML string if it succeeds.

    Examples

    The following code example demonstrates how to export the changed department records from the primary buffer to XML strings using the changedOnly argument. When changedOnly is true, exports the modified data from the primary buffer to an XML string; when changedOnly is false, exports all data from the primary buffer to an XML string.

    using DWNet.Data;
    using System;
    
    namespace Appeon.ApiDoc.DataStoreDataExtensionsExamples
    {
        public class ExportPlainXmlExample
        {
            private readonly SchoolContext _context;
    
            public ExportPlainXmlExample(SchoolContext dataContext)
            {
                // Sets the data context
                _context = dataContext;
            }
    
            public void Example3()
            {
                // Instantiates a DataStore object with datawindow: d_department.
                var datastore = new DataStore("d_department", _context);
    
                // Generates data in the primary/delete/filter buffers for this example.
                datastore.Retrieve();
                datastore.DeleteRow(0);
                datastore.SetItem(0, 1, "department name");
                datastore.SetFilter("departmentid < 5");
                datastore.Filter();
    
                // Exports the modified data from the primary buffer
                string xml1 = datastore.ExportPlainXml(DwBuffer.Primary, true);
    
                Console.WriteLine("datastore.ExportPlainXml(DwBuffer.Primary,true):");
                Console.WriteLine(xml1);
    
                /*The exported XML file is:
    
                ExportPlainXml3_1.xml  
                */
    
                // Exports all data from the primary buffer
                string xml2 = datastore.ExportPlainXml(DwBuffer.Primary, false);
    
                Console.WriteLine("datastore.ExportPlainXml(DwBuffer.Primary, false):");
                Console.WriteLine(xml2);
    
                /*The exported XML file is:
    
                ExportPlainXml3_2.xml  
                */
            }
        }
    }
