IDataStore.GetItemTime(int row, string column, DwBuffer bufferType = DwBuffer.Primary, bool isOriginalValue = false) Method

.NET Standard 2.x

Gets data whose type is TimeSpan for the specified row and column from the specified buffer of the DataStore. You can obtain the data that was originally retrieved and stored in the database, as well as the current value in the primary, delete, or filter buffers.

Namespace: DWNet.Data

Assembly: DWNet.Data.dll

Syntax

  public TimeSpan? GetItemTime(int row, string column, DwBuffer bufferType = DwBuffer.Primary, bool isOriginalValue = false);

Parameters

row System.Int32

The zero-based row number to get data.

column System.String

The name of a column to get data.

To get the contents of a computed field, specify the name of the computed field for column. Computed fields do not have numbers.

bufferType DWNet.Data.DwBuffer

The specified buffer of the DataStore.

isOriginalValue System.Boolean

Whether to obtain the data that was originally retrieved.

True: obtain the data that was originally retrieved; False (default): obtain the current data.

Returns

System.TimeSpan?

Returns the TimeSpan? value in the specified row and column.

Remarks

Use GetItemTime to get information from the DataWindow buffer. When you specify true for isOriginalValue, the method gets the original data for that row.

Examples

The following code example demonstrates how to use the GetItemTime method to get the time-type value in the specified row and column.

using DWNet.Data;
using System;

namespace Appeon.ApiDoc.IDataStoreExamples
{
    public class GetItemTimeExample
    {
        private readonly SchoolContext _context;

        public GetItemTimeExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example2()
        {
            // Instantiates a DataStore object with datawindow: d_coursedescription.
            var datastore = new DataStore("d_coursedescription", _context);

            datastore.Retrieve();
			
			// Sets the "inputtime" column in the first row to "12:12:12".
            datastore.SetItem(0, "inputtime", TimeSpan.Parse("12:12:12"));

            // Gets the original value in the first row and in the description column and 
            // inputtime column of DataStore.
            // The inputtime column is time type.
            Console.WriteLine(
                "Original value: Description: {0};\n" +
                "inputtime: {1}",
                datastore.GetItem<string>(0, "description"),
                datastore.GetItemTime(0, "inputtime", DwBuffer.Primary, true));

            // Gets the modified value in the first row and in the description column and 
            // inputtime column of DataStore.
            // The inputtime column is time type.
            Console.WriteLine(
                "Modified value: Description: {0};\n" +
                "inputtime: {1}",
                datastore.GetItem<string>(0, "description"),
                datastore.GetItemTime(0, "inputtime", DwBuffer.Primary, false));

            /*This code produces the following output:
             
            Original value: Description: Calculus Description;
            inputtime: 08:08:08
            Modified value: Description: Calculus Description;
            inputtime: 12:12:12
            */
        }
    }
}
