Property Value
The object that is the currently selected item or a null reference (Nothing in Visual Basic) if there is no currently selected item.
When you set the SelectedItem property to an object, the ComboBox attempts to make that object the currently selected one in the list. If the object is found in the list, it is displayed in the edit portion of the ComboBox and the SelectedIndex property is set to the corresponding index. If the object does not exist in the list the SelectedIndex property is left at its current value.
The following code example shows the usage of the SelectedIndex and the SelectedItem properties. The example is part of a complete code example in the ComboBox class overview.
Private Sub showSelectedButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim selectedIndex As Integer
selectedIndex = comboBox1.SelectedIndex
Dim selectedItem As Object
selectedItem = comboBox1.SelectedItem
MessageBox.Show("Selected Item Text: " & selectedItem.ToString() & Microsoft.VisualBasic.Constants.vbCrLf & _
"Index: " & selectedIndex.ToString())
End Sub
private void showSelectedButton_Click(object sender, System.EventArgs e) {
int selectedIndex = comboBox1.SelectedIndex;
Object selectedItem = comboBox1.SelectedItem;
MessageBox.Show("Selected Item Text: " + selectedItem.ToString() + "\n" +
"Index: " + selectedIndex.ToString());
}
void showSelectedButton_Click( Object^ sender, System::EventArgs^ e )
{
int selectedIndex = comboBox1->SelectedIndex;
Object^ selectedItem = comboBox1->SelectedItem;
MessageBox::Show( "Selected Item Text: " + selectedItem->ToString() + "\n" +
"Index: " + selectedIndex.ToString() );
}
private void showSelectedButton_Click(Object sender, System.EventArgs e)
{
int selectedIndex = comboBox1.get_SelectedIndex();
Object selectedItem = comboBox1.get_SelectedItem();
MessageBox.Show("Selected Item Text: " + selectedItem.ToString()
+ "\n" + "Index: " + ((Int32)selectedIndex).ToString());
} //showSelectedButton_Click
