How to load an image into a PictureBox - PictureBox Example Part 1

In this mini tutorial I'll explain you how you can set the image to the PictureBox object using the Visual Studio IDE. There are several ways of doing this. The one mentioned here will load an image from a file using the filechooser.
I will explain other ways of loading images at runtime and from a resource object in future posts.

1. Create a Windows Form Application Project.
2. Drag a PictureBox Object to the window in the visual designer.
3. Set the PictureBox image property to the image file you want (select local resource and click "Import").
4. Done, Run your application.

 note: There is no code to add as this method only uses the Visual designer to accomplish this.

Screenshots below:

Create a Windows Form Application Project

Drag a PictureBox Object to the window in the visual designer.

Set the PictureBox image property to the image file you want.

Set the PictureBox image property to the image file you want (select local resource and click "Import").

Choose the file you want to load.

You can add more files to your resource if you want. Click Ok

The Image is displayed on the picturebox.

Run the Application (F5).

ComboBox Part 1 - adding items to the combobox

The ComboBox object provides the same benefits as a list does but it has the ability to expand and contract saving a lot of space in your windows form application.


In the next Quick Example, I'll show you how to add a ComboBox to a Windows Form Application and how to add items in it in two different ways.


1- By passing a range of items (in a list)
2- Adding a specific item by clicking a Button.

1. First, create a Windows Form Application Project

    2. Drag a ComboBox Object to your Window.

    3. Add some code:

     
     I created a List items to store some strings that will then be added at the Load event.
  List<string> items = new List<string>() { "1-Lucia", "2-Mauricio","3-Frank","4-Dog" };

   4. At the Load Event type this line.

    comboBox1.Items.AddRange(items.ToArray());

 5.Then I added a button to show another way of adding items to the combobox

 In the Button Event put this line:

 comboBox1.Items.Add(comboBox1.Items.Count+1+"-Item Added by Button");

FINISHED.

The full Code below (it is all commented)

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace ComboBoxTest

{

    public partial class Form1 : Form

    {

        //creates and initialize a list with strings

        //(could contain any type of object)

        List<string> items = new List<string>() { "1-Lucia", "2-Mauricio", "3-Frank", "4-Dog" };

       

        public Form1()

        {

            InitializeComponent();

        }//constructor

        //The action takes part in the Load event, it could be a button or any other event.

        private void Form1_Load(object sender, EventArgs e)

        {

            //here we load the combobox with the list

            comboBox1.Items.AddRange(items.ToArray());

            //we set the selected to "1-Lucia", it also work with any kind of objects.(it depends on

            //what you put in the list.

            comboBox1.SelectedItem = "1-Lucia";

        }

        private void button_add_Click(object sender, EventArgs e)

        {

            //here we add an item to the combobox manually

            //"comboBox1.Items.Count+1" is just to show the apropiate index in the list

            //it calculates how many items are in the combobox and increments the value by 1

            comboBox1.Items.Add(comboBox1.Items.Count+1+"-Item Added by Button");

        }

      

    }

}

Screenshots:

At this point the ComboBox contains the List.

 

After the add button was clicked. The combobox contains now a new item.

Part 2 will cover the remove method and other combobox specific properties.


See you in the next C# Quick Example.
