IDataStore.RemoveAt(int index) Method

.NET Standard 2.x

Removes the row according to the specified index from the primary buffer of the DataStore. The index is the same as the zero-based row number.

Namespace: DWNet.Data

Assembly: DWNet.Data.dll

Syntax

  public void RemoveAt(int index);

Parameters

index System.Int32

The zero-based index of the row to remove.

Remarks

The RemoveAt method will call the OnRowDeleting method before removing the row, and then call the OnRowDeleted method after removing the row.

Examples

The following code example demonstrates how to remove the DataStore record according to the specified index number.

using DWNet.Data;
using System;

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

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

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

            datastore.Retrieve();

            Console.WriteLine("Before RemoveAt, Rowcount: {0}", datastore.RowCount);

            // Removes the first record of datastore
            datastore.RemoveAt(0);

            Console.WriteLine("After RemoveAt, Rowcount: {0}", datastore.RowCount);

            /*This code produces the following output:
             
            Before RemoveAt, Rowcount: 4
            After RemoveAt, Rowcount: 3
            */
        }
    }
}
