Get selected value from combo box in C# WPF

Question

I have just started using WPF forms instead of Windows Forms forms. In a Windows Forms form I could just do:

ComboBox.SelectedValue.toString();

Answer 1

It works for me:

System.Data.DataRowView typeItem = (System.Data.DataRowView)ComboBoxName.SelectedItem;
string value = typeItem.DataView.ToTable("a").Rows[0][0].ToString();

Answer 2

I have figured it out a bit of a strange way of doing it compared to the old WF forms:

ComboBoxItem typeItem = (ComboBoxItem)cboType.SelectedItem;
string value = typeItem.Content.ToString();

Answer 3

Create a ComboBox SelectionChanged Event and set ItemsSource="{Binding}" in the WPF design:

Code:

private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    string ob = ((DataRowView)comboBox1.SelectedItem).Row.ItemArray[0].ToString();
    MessageBox.Show(ob);
}
