Check if frame is in specified position .net maui

Question

is it possible to check if there is anything in the specified position of a grid?

for example:

if (Frame in Grid.Position(1,7))

{

Console.Write("Specified position is already in use.");

}

I am trying to make a map editor for my own custom game, but frames keep overlapping when you resize it, and I want a way to prevent that from happening.

Hello, Your main purpose is to determine if the point will be in the frame, right? If so, you could try to get the left top point of the frame, and calculate the position of the frame, then judge if the (1,7) point is in the position of frame.

For example:

 public Point GetScreenCoords( VisualElement view)
    {//Get the point in screen, or you can get the Offset in the Parent view according to your needs.

        var result = new Point(view.X, view.Y);
        while (view.Parent is VisualElement parent)
        {
            result = result.Offset(parent.X, parent.Y);
            view = parent;
        }
        return result;
    }

private void OnCounterClicked(object sender, EventArgs e)
      {
        var result = GetScreenCoords(MyFrame);
        double a = result.X + MyFrame.Width;
        double b = result.Y + MyFrame.Height;//calculate the range
        if ((result.X<1 && 1 < a) && (result.Y<7 && 7< b))
            {
                  Console.WriteLine("Specified position is already in use.");
            }
    }
