I have a combox in my wpf application with three items:

```
<ComboBoxItem Tag="some value">Text</ComboBoxItem>
<ComboBoxItem Tag="some value2">Text2</ComboBoxItem>
<ComboBoxItem Tag="some value3">Text3</ComboBoxItem>

```

I want to get a selected text or value at runtime. When I do this:

```
myComboBox.SelectedValue.ToString()

```

it returns this:

```
System.Windows.Controls.ComboBoxItem: Text2

```

How can I get a selected text or value?
