I created two properties for button in master page

public Button test { get { return Button1; } }
public Button print { get { return Button4; } }

in child page:
Master.print.Click += DesignationGridLoad(); showing error cannot implicity covert system type to event handler.

where to create interface

Hi,
The best way to use master page control by creating one interface and inherit it in master page.
Create one interface

public interface IMasterPage
{
Button PrintButton { get; set; }
}

Inherit it and assign the property value

public partial class Sitemaster1 : System.Web.UI.MasterPage, IMasterPage
{
public Button PrintButton { get; set; }

protected void Page_Load(object sender, EventArgs e)
{
PrintButton = Button4;
}
}

in your child page

protected void Page_Load(object sender, EventArgs e)
{
IMasterPage masterPage = (IMasterPage)Page.Master;
if (masterPage != null) masterPage.PrintButton.Click += DesignationGridLoad();
}
