Winform下Textbox的样式(1)—TextBox_Bind

public class TextBox_Bind:TextBox
    {
        public DataView BindDataViewSource=null;
        public string BindField=null;
        public TextBox_Bind( ):base()
        {

        }
        public void Bind()
        {
            base.DataBindings .Add (new System .Windows .Forms .Binding ("Text",BindDataViewSource,BindField));
        }
        public virtual void Next()
        {
            base.BindingContext[BindDataViewSource].Position +=1;
        }
        public virtual void Forward()
        {
            base.BindingContext[BindDataViewSource].Position -=1;    
        }
        public virtual void MoveStart()
        {
            base.BindingContext[BindDataViewSource].Position=0;
        }
        public virtual void MoveEnd()
        {
            base.BindingContext [BindDataViewSource].Position=BindDataViewSource.Count ;
        }
        public virtual void MoveTo(int CurrentRecord)
        {
            if (CurrentRecord<BindDataViewSource.Count && CurrentRecord>=0)
            {
                base.BindingContext [BindDataViewSource].Position=CurrentRecord;
            }
        }
    }

TextBox_Bind类功能比较简单，只实现了自动绑定，记录移动。
