如何将numericUpDown双向绑定到成员类

我需要twoway绑定configClass.RaMsize到numericUpDown。

BindField(this.upDownRamSize, "Value", configClass, "RaMsize");//all right this.upDownRamSize.Value = 1213;// configClass.RaMsize - not change - it's bad! 

方法：

 public static void BindField(Control control, string propertyName, object dataSource, string dataMember) { Binding bd; for (int index = control.DataBindings.Count - 1; (index == 0); index--) { bd = control.DataBindings[index]; if (bd.PropertyName == propertyName) control.DataBindings.Remove(bd); } control.DataBindings.Add(propertyName, dataSource, dataMember); } 

Answer 1

我假设ConfigClass看起来像：

 public class ConfigClass { public decimal RaMsize { get; set; } } 

所以改变control.DataBindings.Add(propertyName, dataSource, dataMember); 至：

 control.DataBindings.Add(propertyName, dataSource, dataMember, false, DataSourceUpdateMode.OnPropertyChanged); 

测试：

 BindField(this.upDownRamSize, "Value", configClass, "RaMsize"); this.upDownRamSize.Value = 1213;// configClass.RaMsize will also have 1213
