Question

如何让label控件的text属性随着combolistbox的选项变化而变化

Answer 1

You could use Data Binding. The following is a simple sample since I am still learning Data Binding.
cotr{
InitializeComponent();
m_CustomersBindingSource.DataSource = GetTestCustomerCollection(); // return BindingList<Customer>
...
comboBox1.DataSource = m_CustomersBindingSource; //System.Windows.Forms.BindingSource
comboBox1.DisplayMember = "CustomerName";
comboBox1.ValueMember = "CustomerId";
...
textBox1.DataBindings.Add( "Text", m_CustomersBindingSource, "CustomerName" );
}
