//Line 83
    System.Windows.Controls.Grid chartTraderGrid = ((Window.GetWindow(ChartControl.Parent).FindFirst("ChartWindowChartTraderControl") as ChartTrader).Content as System.Windows.Controls.Grid).Children[0] as System.Windows.Controls.Grid;




            BuyMarketButton = chartTraderGrid.FindFirst("ChartTraderControlQuickBuyMarketButton") as System.Windows.Controls.Button;

            SellMarketButton = chartTraderGrid.FindFirst("ChartTraderControlQuickSellMarketButton") as System.Windows.Controls.Button;

            Print(chartTraderGrid.RowDefinitions.Count);​

I have several questions that I haven't found an answer to:

1. Is it possible to find the names "ChartTraderControlQuickSellMarketButton, ChartTraderControlQuickBuyMarketButton..." without using Inspect?
2. How do I iterate through the elements (next, previous,last)?
3. I have add this line:

    Print(chartTraderGrid.RowDefinitions.Count);

   The result is 11, but I don't know how it found 11 rows in the chart.
   
   thank for your help

Hello aekzof,

You would need to use inspect or Accessibility Insights to locate ids in the platform. That is the easiest way to locate ids by selecting a specific control. Unless you know C#/ WPF very well to write your own C# logic to navigate the visual tree that would be the only way. This is something you could research in external C# websites if you wanted to learn more about automation ids and the WPF visual tree.

Your print is printing the count of the definitions in the grid, there are 11 rows in your current grid. The grid you are looking at is the chart trader control which has many rows and columns to support the other WPF controls it contains.

You can learn more about using WPF grids in external C#/WPF learning resources.
