Insert an Array Element at Specific Position in Windows Store App

In this article I explain how to insert an element at specific position in Windows Store App.

Introduction

In my previous article I described how to Delete specific element of an array and in this article I explain how to insert an element at a specific position and also do not increate the size of the array.

Use the following procedure to create it.

Step 1

First of all you must create a new Windows Store Application.

  • Open Visual Studio 2012
  • "File" -> "New" -> "Project..."
  • Choose "Template" -> "Visual C#" -> "Window Store app"
  • Choose "Blank App (XAML)" then rename the application

    Step 2

    Write the following XAML code in "Mainpage.Xaml" (that is available in Solution Explorer):

    <Page

        x:Class="delete_specific_element_from_array.MainPage"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:local="using:delete_specific_element_from_array"

        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

        mc:Ignorable="d">

     

        <Grid Background="red">

            <Grid.RowDefinitions>

                <RowDefinition Height="72*"/>

                <RowDefinition Height="38*"/>

                <RowDefinition Height="42*"/>

                <RowDefinition Height="35*"/>

                <RowDefinition Height="40*"/>

                <RowDefinition Height="79*"/>

                <RowDefinition Height="36*"/>

                <RowDefinition Height="33*"/>

                <RowDefinition Height="40*"/>

                <RowDefinition Height="42*"/>

                <RowDefinition Height="311*"/>

            </Grid.RowDefinitions>

            <Grid.ColumnDefinitions>

                <ColumnDefinition Width="248*"/>

                <ColumnDefinition Width="407*"/>

                <ColumnDefinition Width="257*"/>

                <ColumnDefinition Width="454*"/>

            </Grid.ColumnDefinitions>

           

            <TextBlock Text="Enter Element of an array" FontFamily="Arial" Grid.Column="1" Grid.Row="2" Foreground="White" FontSize="20" FontWeight="ExtraBold" ></TextBlock>

            <TextBox x:Name="textbox1" Grid.Column="2" Grid.Row="2" Width="200" HorizontalAlignment="Left" VerticalAlignment="Top" Height="32"></TextBox>

            <Button x:Name="button1" Content="Insert" Grid.Column="2" Grid.Row="3" Background="Yellow" Foreground="Black" Width="97" Height="35" Click="button1_Click" ></Button>

            <TextBlock x:Name="text1" FontFamily="Arial" Grid.Column="3" Grid.Row="2" FontSize="20" FontWeight="ExtraBold" ></TextBlock>

            <Button x:Name="button2" Content="show array element" Background="Yellow" Foreground="Black" Grid.Column="2" Grid.Row="4" Height="40" Width="171" Click="button2_Click"/>

            <TextBlock x:Name="text2" FontFamily="Arial" Grid.Column="1" Grid.Row="5" FontSize="20" FontWeight="ExtraBold" ></TextBlock>

            <TextBlock Text="Enter the position for insert Number" FontFamily="Arial" Grid.Column="1" Grid.Row="6" FontSize="20" FontWeight="ExtraBold" Grid.RowSpan="2" ></TextBlock>

            <TextBox x:Name="textbox2" Grid.Column="2" Grid.Row="6" Width="200" HorizontalAlignment="Left" VerticalAlignment="Top" Height="32"></TextBox>

            <Button x:Name="button3" Content="Inset at position" Grid.Column="2" Grid.Row="8" Background="Yellow" Foreground="Black" Width="200" Height="35" Margin="0,5,0,0" Click="button3_Click" />

            <Button x:Name="button4" Content=" Show after Delete array element" Grid.Column="2" Grid.Row="8" Background="Yellow" Foreground="Black" Width="257" Height="35" Margin="0,38,0,9" Click="button4_Click" Grid.RowSpan="2" />

            <TextBlock Text="Enter Element to insert" FontFamily="Arial" Grid.Column="1" Grid.Row="7" FontSize="20" FontWeight="ExtraBold" Grid.RowSpan="2" ></TextBlock>

            <TextBlock x:Name="text3" FontFamily="Arial" Grid.Column="1" Grid.Row="10" FontSize="20" FontWeight="ExtraBold" ></TextBlock>

            <TextBox x:Name="textbox3" Grid.Column="2" Grid.Row="7" Width="200" HorizontalAlignment="Left" VerticalAlignment="Top" Height="32" />

        </Grid>

    </Page>

    Step 3

    Now write the following C# code for the button within "Mainpage.Xaml.cs".

    using System;

    using System.Collections.Generic;

    using System.IO;

    using System.Linq;

    using Windows.Foundation;

    using Windows.Foundation.Collections;

    using Windows.UI.Xaml;

    using Windows.UI.Xaml.Controls;

    using Windows.UI.Xaml.Controls.Primitives;

    using Windows.UI.Xaml.Data;

    using Windows.UI.Xaml.Input;

    using Windows.UI.Xaml.Media;

    using Windows.UI.Xaml.Navigation;

     

    namespace delete_specific_element_from_array

    {

        public sealed partial class MainPage : Page

        {

            public MainPage()

            {

                this.InitializeComponent();

            }

            protected override void OnNavigatedTo(NavigationEventArgs e)

            {

            }

            int[] arr = new int[5];

            int i = 0;

            private void button1_Click(object sender, RoutedEventArgs e)

            {

                if (i < arr.Length)

                {

                    arr[i] = int.Parse(textbox1.Text);

                    i++;

                    textbox1.Text = " ";

                }

                else

                {

                    text1.Text = "Sorry array can contain only 5 element";

                }

            }

     

            private void button2_Click(object sender, RoutedEventArgs e)

            {

                for (int i = 0; i < arr.Length; i++)

                {

                    text2.Text += arr[i] + " ";

                }

            }

     

            private void button3_Click(object sender, RoutedEventArgs e)

            {

                int pos = int.Parse(textbox2.Text);

                if (pos <= arr.Length)

                {

                    int value = int.Parse(textbox3.Text);           

                        arr[pos] = value;

                }

              

            }

            private void button4_Click(object sender, RoutedEventArgs e)

            {

                foreach (int a in arr)

                {

                    text3.Text += a + " ";

                }

            }

        }

    }

     

    Step 4

    Now Run your app.
