Slow to get element with TestStack.White

Question

So what I'm doing is using the .Exist<T> method in TestStack.White to see if an error dialog box exists. The problem I'm having is that finding it is EXTREMELY slow. This is due to the fact the the program has a data table in it with over 400 items, and then sub items of those items. I'm not really sure how I can make this search quicker, here's the box I'm trying to see if exists:

And here is the code I'm using to pull it:

private bool GrabErrorOrExucute()
        {
            using (CoreAppXmlConfiguration.Instance.ApplyTemporarySetting(s => s.BusyTimeout = 500))
            {
                if (_mainWindow.Exists(SearchCriteria.ByAutomationId("65535")))
                {
                    var error = _mainWindow.Get(
                        SearchCriteria
                            .ByAutomationId(
                                "65535")); 
                    MessageBox.Show("Error has been thrown while getting rates, it will be displayed now...",
                        "Error While Getting Rates", MessageBoxButtons.OK, MessageBoxIcon.Error,
                        MessageBoxDefaultButton.Button1, MessageBoxOptions.DefaultDesktopOnly);
                    MessageBox.Show(error.Name, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error,
                        MessageBoxDefaultButton.Button1, MessageBoxOptions.DefaultDesktopOnly);


                    var okbtn = _mainWindow.Get<Button>(SearchCriteria.ByAutomationId("2"));
                    ratestat.Text = "Error While Getting Rate...";
                    Stop();
                    return true;
                }


                return false;
            }
        }

This can take well over 10-15 minutes minutes because of the table that is in the program. Here's what the table looks like (Which goes from 1 to ~400). How do I make this faster?:

Answer 1

Try to use: CoreAppXmlConfiguration.Instance.RawElementBasedSearch = true; somewhere before test. Another option is to limit search depth: CoreAppXmlConfiguration.Instance.RawElementBasedSearch = true;

For me theese two aproaches allow good performance compared to default
