selected checkbox in wpf

Question

how i can get those selected checkbox in a stackpanel

Not sure what your scenario is, but if these checkboxes represent data points (e.g. which purchase orders are approved) rather than being controls with a specific behavioural purpose, it's easier and more idiomatic in WPF to use a databound ItemsControl or ListBox, with the CheckBox as part of its DataTemplate. — itowlson

You can query the children of the stackpanel.

IEnumerable<CheckBox> selectedBoxes =
    from checkbox in this.stackPanel1.Children.OfType<CheckBox>()
    where checkbox.IsChecked.Value
    select checkbox;

foreach (CheckBox box in selectedBoxes)
{
    // do something 
}

Same query in lambda form

IEnumerable<CheckBox> selectedBoxes =
    this.stackPanel1.Children.OfType<CheckBox>()
    .Where(cb => cb.IsChecked.Value);

You can make this easier with the OfType operator: from cb in stackPanel1.Children.OfType<CheckBox>() where cb.IsChecked.Value select cb. Saves the test in the where clause and the repeated casts.
