Examples
The following example shows how to use the SelectedIndex property to determine whether an item is selected in a ListView control. This code example is part of a larger example provided for the DeleteItem method.
protected void DeleteButton_Click(object sender, EventArgs e)
{
//Check if an item is selected to delete it.
if (ContactsListView.SelectedIndex >= 0)
ContactsListView.DeleteItem(ContactsListView.SelectedIndex);
else
Message.Text = "No contact was selected.";
}
Protected Sub DeleteButton_Click(ByVal sender As Object, ByVal e As EventArgs)
' Check if an item is selected to delete it.
If ContactsListView.SelectedIndex >= 0 Then
ContactsListView.DeleteItem(ContactsListView.SelectedIndex)
Else
Message.Text = "No contact was selected."
End If
End Sub
Remarks
Use the SelectedIndex property to determine the index of the currently selected item in a ListView control. You can also use this property to programmatically select an item in the control. (However, if you manually data-bind the ListView control, you might have to handle reading or setting this property manually as well.)
