How to change back color of window form using Track Bars in C#?

Hello Friends! In this article we will learn that how build or make 3 different Track Bars in C# using window forms. These track bars will use to set the background color of the form. These kind of applications will realy increase your love for c#. So Open your Visual Studio and try to make app like this and follow my article step by step.

Here is the screenshot of that track bar app that I built with different tools available in tool box for window forms:

So in the above picture you can see different tools that I have used with final out put. These tools can be drag and drop from toolbox as I mentioned previously.

Lets try to code this application.

Source Code C#:

___________________________________________________________________________

using System;

using System.Drawing;

using System.Windows.Forms;

namespace TR_Track_Bar

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void trackBar1_Scroll(object sender, EventArgs e)

        {

            //store the track bar1 current value to the label1 text

            label1.Text = trackBar1.Value.ToString();

            //change the background of form according to the current value of all 3 bars

            BackColor = Color.FromArgb(hScrollBar1.Value, hScrollBar2.Value, trackBar1.Value);

        }

        private void hScrollBar1_Scroll(object sender, ScrollEventArgs e)

        {

            //store the scroll bar1 current value to the label2 text

            label2.Text = hScrollBar1.Value.ToString();

            //change the background of form according to the current value of all 3 bars

            BackColor = Color.FromArgb(hScrollBar1.Value, hScrollBar2.Value, trackBar1.Value);

        }

        private void hScrollBar2_Scroll(object sender, ScrollEventArgs e)

        {

            //store the scroll bar2 current value to the label3

            label3.Text = hScrollBar2.Value.ToString();

            //change the background of form according to the current value of all 3 bars

            BackColor = Color.FromArgb(hScrollBar1.Value, hScrollBar2.Value, trackBar1.Value);

        }

    }

}

In above code one thing to remember that Argb stands for Alpha, red, green and blue will take all 3 bars values as RGB values and change the background color of window form according to these values.

Here is the final output when you run you code.
