Hello Uday,

Please make a lost focus handler. Use this handler to set focus back to the
button. Here is an example I have made for you.

package KeyApp;
import System.Drawing.*;
import System.Collections.*;
import System.ComponentModel.*;
import System.Windows.Forms.*;
import System.Data.*;

public class Form1 extends System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Button button2;
private System.ComponentModel.Container components = null;

public Form1()
{
 InitializeComponent();
}

protected void Dispose(boolean disposing)
{
 if (disposing)
 {
  if (components != null)
  {
   components.Dispose();
  }
 }
 super.Dispose(disposing);
}

private void InitializeComponent()
{
 this.button1 = new System.Windows.Forms.Button();
 this.button2 = new System.Windows.Forms.Button();
 this.SuspendLayout();
 //
 // button1
 //
 this.button1.set_Location(new System.Drawing.Point(136, 96));
 this.button1.set_Name("button1");
 this.button1.set_TabIndex(0);
 this.button1.set_Text("button1");
 this.button1.add_KeyUp( new
System.Windows.Forms.KeyEventHandler(this.ButtKeyHandler) );
 this.button1.add_Leave( new System.EventHandler(this.focusme) );
 //
 // button2
 //
 this.button2.set_Location(new System.Drawing.Point(136, 176));
 this.button2.set_Name("button2");
 this.button2.set_TabIndex(1);
 this.button2.set_Text("button2");
 this.button2.add_Click( new System.EventHandler(this.button2_Click) );
 //
 // Form1
 //
 this.set_AutoScaleBaseSize(new System.Drawing.Size(5, 13));
 this.set_ClientSize(new System.Drawing.Size(616, 486));
 this.get_Controls().Add(this.button2);
 this.get_Controls().Add(this.button1);
 this.set_Name("Form1");
 this.set_Text("Form1");
 this.add_KeyUp( new
System.Windows.Forms.KeyEventHandler(this.KeyHandler) );
 this.ResumeLayout(false);
}

/**
 * The main entry point for the application.
 */
/** @attribute System.STAThread() */
public static void main(String[] args)
{
 Application.Run(new Form1());
}

private void KeyHandler (Object sender, System.Windows.Forms.KeyEventArgs
e)
{
 ButtKeyHandler( sender, e );
}

private void ButtKeyHandler (Object sender,
System.Windows.Forms.KeyEventArgs e)
{
 // Left
 if ( e.get_KeyValue() == 39 )
 {
  this.button1.set_Location( new System.Drawing.Point(
   this.button1.get_Location().get_X() + 5,
   this.button1.get_Location().get_Y()) );
 }

 // down
 if ( e.get_KeyValue() == 40 )
 {
  this.button1.set_Location( new System.Drawing.Point(
   this.button1.get_Location().get_X(),
   this.button1.get_Location().get_Y() + 5) );
 }

 // Right
 if ( e.get_KeyValue() == 37 )
 {
  this.button1.set_Location( new System.Drawing.Point(
   this.button1.get_Location().get_X() - 5,
   this.button1.get_Location().get_Y()) );
 }

 // Up
 if ( e.get_KeyValue() == 38 )
 {
  this.button1.set_Location( new System.Drawing.Point(
   this.button1.get_Location().get_X(),
   this.button1.get_Location().get_Y() - 5) );
 }
 this.button1.Focus();
}

// Sets the focus back to the button.
private void focusme (Object sender, System.EventArgs e)
{
 this.button1.Focus();
}

private void button2_Click (Object sender, System.EventArgs e)
{
 System.Windows.Forms.MessageBox.Show("I'm button 2");
}
}
