我有一个绑定到数据源的ComboBox但它不会更新绑定,直到控件失去焦点.如何在所选项目更改时获取更新绑定？在下面的屏幕截图中,我希望标签立即更新以反映新的选择.
一些代码：
public enum MyEnum
{
First,Second
}
public class MyData
{
public String Name { get; set; }
public MyEnum MyEnum { get; set; }
}
样品表格：
public SampleForm()
{
InitializeComponent ();
MyData data = new MyData () { Name = "Single Item" };
this.bindingSource1.DataSource = data;
this.comboBox1.DataSource = Enum.GetValues (typeof (MyEnum));
this.label2.DataBindings.Add ("Text",this.bindingSource1,"MyEnum",true,DataSourceUpdateMode.OnPropertyChanged);
this.comboBox1.DataBindings.Add (new System.Windows.Forms.Binding ("SelectedItem",true));
this.comboBox1.DataBindings.Add (new System.Windows.Forms.Binding ("SelectedValue",true));
}
