Rather than sending mouse events, you can Invoke it through the InvokePattern like so:

public void InvokeAutomationElement(AutomationElement automationElement)
{
    var invokePattern = automationElement.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern;
    invokePattern.Invoke();
}

Not all windows support Invoke pattern – Max Dec 12 '12 at 12:56

This is true, but I'm guessing that if you can click on it you can do it with automation (and not mouse clicking). If it doesn't support the Invoke pattern, it probably supports the `SelectionItemPattern`, so you can `Select` it. – Levi Dec 15 '12 at 02:25
I've seen windows which only support WindowPattern and TransformPattern. From the question I cannot tell why the click is performed. It can be that Stacker wants to bring the window to focus (just a guess). So there's might be no immediate activity that is going to be "invoked". – Max Dec 15 '12 at 23:32

try with:

AutomationElement child = walker.GetFirstChild(el);
System.Windows.Point p = child.GetClickablePoint();
Mouse.Move((int)p.X, (int)p.Y);
Mouse.Click(MouseButton.Left);

What should i reference to get access to Mouse class? – Stacker Apr 11 '12 at 13:29
I will try this , although i think that just getting the x and y to click will cause the problem of the mouse not aware what its clicking so the element could be not on top of the window and that would cause the click to be at no where – Stacker Apr 11 '12 at 14:05
If the element is hidden getclickablepoint does not return a valid point. I. Which case you can bring the window to the front first. – Cilvic Apr 12 '12 at 05:28
@Jack I don't know, you can ask to Stacker – andres descalzo Nov 14 '16 at 19:23
Nevermind it. I thought it was relevant to get the right clickable point but it isn't. – Jack Nov 14 '16 at 19:28

If the control has a "ClickablePoint" you can use this code

System.Windows.Point p = theButton.GetClickablePoint();
AutoItX3Lib.AutoItX3Class au3 = new AutoItX3Lib.AutoItX3Class();
au3.AutoItSetOption("MouseCoordMode", 0);
au3.MouseClick("LEFT", (int)p.X, (int)p.Y, 1, -1);

where AutoItX3Lib is the C# API for AutoIt (available on NuGet)
