ASP.NET - How to show menu in asp.net on button click

I need to show menu on button click 

Please help ASAP 

Hide the menu with your css display:none and then use jquery to display it:

$(document).ready(function() {
$(yourclass/idhere).toggle();
});

Thanks

Sure (not tested but this should work)

protected void yourMenu_MenuItemDataBound(object sender, MenuEventArgs e)
{
 // Add a client-side onclick event handler to the "Home" menu item...
 if ( e.Item.Text == "Home" )
 {
   e.Item.Attributes.Add("onclick", "return getFile();");
 }
}
