C# lamda expression to get list of values of cehcked items

[Aarsh]

At the moment I have to break down this simple operation in two parts, I am sure the would be a better way is hiding from me :

List<int> selectedValues= new List<int>();

.
.
.

IEnumerable<RadComboBoxItem> checkedItems = from checkedItem in cblMagistrateCourts.Items.ToList()
                                                                where checkedItem.Checked == true
                                                                select checkedItem;
                    foreach (RadComboBoxItem item in checkedItems)
                    {
                        if (item.Checked)
                            selectedValues.Add(Convert.ToInt32(item.Value));
                    }
