Question

How do you access the children of a WPF Canvas class?

It is a cool class and I like how you are able to add children. But once they are there, how to you look at them for reading their state and content. I know it is easy if you put the children in XAML. But what if you have added children to the canvas dynamically at run time?

Solution

You can use the Children property.

Edit: Here is an example of iterating over the children and getting one by index:

foreach (UIElement child in canvas.Children)
{
    // ...
}
// Or: 
int index = 0;
var childByIndex = canvas.Children[index];
