Convert a UIElement to an Object?

Question

How would I go about converting a UIElement to a, in this problem, CartesianChart (LiveCharts).

In this code, I check for a Grid for a CartesianChart and then I want to store it (in ch).

            CartesianChart ch;

            for (int i = 0; i < Grid.Children.Count; i++)
            {
                var temp = Grid.Children[i].GetType();
                if (temp.Name == "CartesianChart")
                {
                    ch = Grid.Children[i];
                }
            }
            ch.Name = "Chart";
            ch.Margin = new Thickness(0, 0, 250, 125);
            ch.Series = new SeriesCollection

It says are you missing a cast?, but I'm unsure of how to cast a UIElement to an Object.

Answer 1

You can use as operator

 ch = Grid.Children[i] as CartesianChart;

or cast operator

ch = (CartesianChart)Grid.Children[i];

The main difference between them is explained here

I would recommend to use first approach. It can look like

 CartesianChart ch = null; // this lets avoid a compiler warning about using uninitialized vars
 for (int i = 0; i < Grid.Children.Count; i++)
 {
    ch = Grid.Children[i] as CartesianChart;
    if (ch != null)
    {
       break;
    }
 }
 if (ch != null)
 {
     ch.Name = "Chart";
     ch.Margin = new Thickness(0, 0, 250, 125);
     ch.Series = new SeriesCollection ...
 }

Please take into account, this code will find a first CartesianChart in the grid (if you can have several ones, you should perform additional checks).
