c# - Get tag of selected item in WPF ComboBox

Question

I have combobox like this:

<ComboBox Name="ExpireAfterTimeComboBox" Margin="5" SelectedIndex="0">
    <ComboBoxItem Content="15 minutes" Tag="15" />
    <ComboBoxItem Content="30 minutes" Tag="30" />
    <ComboBoxItem Content="1 hour" Tag="60" />
    <ComboBoxItem Content="1 day" Tag="1440" />
</ComboBox>

How do I get Tag value in code?

writing something like ExpireAfterTimeComboBox.SelectedItem.Tag doesn't work.

Answer 1

You need to cast it to a type of ComboBoxItem.

  var selectedTag = ((ComboBoxItem)ExpireAfterTimeComboBox.SelectedItem).Tag.ToString();
