Drag And Drop/Mouse Move using Selenium WebDriver

Javascript based drag and drop which works across browsers.

Mouse move stopped working after version 2.3 while using RemoteWebDriver in selenium.
The below function drags element 1 to element 2 position and releases the mouse down.

public void dragdrop(By ByFrom, By ByTo) {
	WebElement LocatorFrom = driver.findElement(ByFrom);
	WebElement LocatorTo = driver.findElement(ByTo);
	String xto=Integer.toString(LocatorTo.getLocation().x);
	String yto=Integer.toString(LocatorTo.getLocation().y);
	((JavascriptExecutor)driver).executeScript("function simulate(f,c,d,e){var b,a=null;for(b in eventMatchers)if(eventMatchers[b].test(c)){a=b;break}if(!a)return!1;document.createEvent?(b=document.createEvent(a),a==\"HTMLEvents\"?b.initEvent(c,!0,!0):b.initMouseEvent(c,!0,!0,document.defaultView,0,d,e,d,e,!1,!1,!1,!1,0,null),f.dispatchEvent(b)):(a=document.createEventObject(),a.detail=0,a.screenX=d,a.screenY=e,a.clientX=d,a.clientY=e,a.ctrlKey=!1,a.altKey=!1,a.shiftKey=!1,a.metaKey=!1,a.button=1,f.fireEvent(\"on\"+c,a));return!0} var eventMatchers={HTMLEvents:/^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,MouseEvents:/^(?:click|dblclick|mouse(?:down|up|over|move|out))$/}; " +
	"simulate(arguments[0],\"mousedown\",0,0); simulate(arguments[0],\"mousemove\",arguments[1],arguments[2]); simulate(arguments[0],\"mouseup\",arguments[1],arguments[2]); ",
	LocatorFrom,xto,yto);
}

To only simulate a mousemove -
xto – is the x position of the element, yto – is the y position of the element, LocatorFrom – is the from WebElement

((JavascriptExecutor)driver).executeScript("function simulate(f,c,d,e){var b,a=null;for(b in eventMatchers)if(eventMatchers[b].test(c)){a=b;break}if(!a)return!1;document.createEvent?(b=document.createEvent(a),a==\"HTMLEvents\"?b.initEvent(c,!0,!0):b.initMouseEvent(c,!0,!0,document.defaultView,0,d,e,d,e,!1,!1,!1,!1,0,null),f.dispatchEvent(b)):(a=document.createEventObject(),a.detail=0,a.screenX=d,a.screenY=e,a.clientX=d,a.clientY=e,a.ctrlKey=!1,a.altKey=!1,a.shiftKey=!1,a.metaKey=!1,a.button=1,f.fireEvent(\"on\"+c,a));return!0} var eventMatchers={HTMLEvents:/^(?:load|unload|abort|error|select|change|submit|reset|focus|blur|resize|scroll)$/,MouseEvents:/^(?:click|dblclick|mouse(?:down|up|over|move|out))$/}; " +
 "simulate(arguments[0],\"mousemove\",arguments[1],arguments[2]);",LocatorFrom,xto,yto);
