Design :-

•  Generate theEventHandlers  optRed,optGreen,optBlue,optWhite,optCyan,optGold,optYellow,optBlack  CheckBoxes CheckedChanged Events
• Generate the EventHandlers for btnPrevious,btnNext Buttons Click Events
•  write the following code in Source[FormTabControl.cs] 

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 WABasics {     public partial class FormTabControl : Form     {         public FormTabControl()         {             InitializeComponent();         }         private void optRed_CheckedChanged(object sender, EventArgs e)         {             txtSample.BackColor = Color.Red;         }         private void optGreen_CheckedChanged(object sender, EventArgs e)         {             txtSample.BackColor = Color.Green;         }         private void optBlue_CheckedChanged(object sender, EventArgs e)         {             txtSample.BackColor = Color.Blue;         }         private void optWhite_CheckedChanged(object sender, EventArgs e)         {             txtSample.BackColor = Color.White;         }         private void btnNext_Click(object sender, EventArgs e)         {             tabControl1.SelectedIndex = tabControl1.SelectedIndex + 1;         }         private void Cyan_CheckedChanged(object sender, EventArgs e)         {             txtSample.ForeColor = Color.Cyan;         }         private void optGold_CheckedChanged(object sender, EventArgs e)         {             txtSample.ForeColor = Color.Gold;         }         private void Yellow_CheckedChanged(object sender, EventArgs e)         {             txtSample.ForeColor = Color.Yellow;         }         private void optBlack_CheckedChanged(object sender, EventArgs e)         {             txtSample.ForeColor = Color.Black;         }         private void btnPrevious_Click(object sender, EventArgs e)         {             tabControl1.SelectedIndex = tabControl1.SelectedIndex - 1;         }             } }

Result :-
