ListControl.SelectedValue Property

If a property is not specified in ValueMember, SelectedValue returns the results of the ToString method of the object.

SelectedIndex , SelectedValue, and FormattingEnabled are related as follows:

• If FormattingEnabled is false, SelectedIndex will not be set to -1 when SelectedValue is blank.

• If FormattingEnabled is true, SelectedIndex will be set to -1 when SelectedValue is blank.

The following code example shows the SelectedValue returning the value of the property specified by the ValueMember property. This code is an excerpt from the example shown in the ListControl class overview. See ListControl for the whole code listing.

private void ListBox1_SelectedValueChanged(object sender, EventArgs e)
{
    if (ListBox1.SelectedIndex != -1)
    {
        textBox1.Text = ListBox1.SelectedValue.ToString();
        // If we also wanted to get the displayed text we could use
        // the SelectedItem item property:
        // string s = ((USState)ListBox1.SelectedItem).LongName;
    }
}
