I am Created UserControl explicitly have code below :-
namespace test_CreateUserControl
{

public partial class UserControl1 : UserControl
{
// public event EventHandler StatusChanged;
public event EventHandler InnerButtonClick;
public UserControl1()
{
InitializeComponent();
InnerButton.Click +=new EventHandler(InnerButton_Click);
}
private void InnerButton_Click(Object sender, EventArgs e)
{
if (InnerButtonClick != null)
{
InnerButtonClick(InnerButton, e);

}
}
/* protected virtual void OnStatusChanged(EventArgs e)
{
EventHandler eh = StatusChanged;
if (eh != null)
{
eh(this, e);
}
}

private void Button1_Click(object sender, EventArgs e)
{
OnStatusChanged(new EventArgs());
}*/
}
}

Then successfully usercontrol added with tool then code again in Form1

namespace test_CreatePannel
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private System.Windows.Forms.Button Button1;
private System.Windows.Forms.Button Button2;
private System.Windows.Forms.Button Button3;
private void userControl11_Load(object sender, EventArgs e)
{
label1.Text = "UserControl loaded";
}

private void InnerButton(object sender, EventArgs e)
{
label1.Text = "This is Clicked by inner Button";
