[SOLVED] Why isn't the Mouse.DoubleClick functioning properly when the Coded UI test is executed via MTM?

Why isn't the Mouse.DoubleClick functioning properly when the Coded UI test is executed via MTM?

What I'm trying to is to double click on a row in a WPF datagrid. To achieve this I'm using the following code:

WpfTable invoiceList = new WpfTable(base.MainWindow);
invoiceList.SearchProperties.Add(WpfTable.PropertyNames.AutomationId, "datagridID");
invoiceList.WaitForControlReady(15000);

Mouse.DoubleClick(invoiceList.GetRow(0));

When I run this on my machine the test passes but when I run the same test via MTM I get the following error:

Test method org.Application.Automation.TestCases.CommentsTests.VerifyExistingCommentsTest threw exception: Microsoft.VisualStudio.TestTools.UITest.Extension.PlaybackFailureException: Cannot perform 'DoubleClick' on the control. Additional Details: TechnologyName: 'UIA' ControlType: 'Row' FrameworkId: 'WPF' ---> System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.

Could someone point in the right direction as to how I could fix this?

Solution

In case anyone else is facing this issue, I changed my code to the following to get it to work.

WpfControl row = invoiceList.GetRow(0);
row.WaitForControlReady();

Mouse.DoubleClick(new System.Drawing.Point(row.BoundingRectangle.X + row.BoundingRectangle.Width, row.BoundingRectangle.Y + row.BoundingRectangle.Height/2));

So instead of double clicking on the WpfRow object, I used the Mouse.DoubleClick(new System.Drawing.Point()) option and passed center point (i.e System.Drawing.Point) as the parameter. As to why the previous approach didn't work, I'm afraid I cannot explain.
