DevExpress控件的一些快捷操作

用的DevExpress控件时，有一些操作并不太方便，根据我自己需要的封装了一些控件的事件，调用的时候直接绑定控件的事件就可以了

例如:

this.ComboBoxEdit.KeyDown += CtrlBase.ComboBoxEdit_KeyDown;
            this.LookUpEdit.KeyDown +=CtrlBase.LookUpEdit_KeyDown;
            this.TextEdit.KeyDown += CtrlBase.TextEdit_KeyDown;
            this.searchLookUpEdit.KeyDown += CtrlBase.searchLookUpEdit_KeyDown;
            this.MemoEdit.KeyDown += CtrlBase.MemoEdit_KeyDown;

1:实现回车跳转下一个控件

首先把需要跳转的控件的TabIndex属性设置为连续的数字，这些数字控制跳转顺序，一般都是从1开始。

然后给控件绑定写好的事件，(如下图)就可以实现回车跳转到下一个控件

2:实现ComboBoxEdit、LookUpEdit控件↓键调出下拉列表

只需要给ComboBoxEdit、LookUpEdit绑定写好事件就可以实现了

3:把绑定的事件封装在一个类里,方便下次调用

  public class CtrlBase
    {
        public static void ComboBoxEdit_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                SendKeys.Send("{TAB}");  //按Enter键时调用按Tab键时候的默认方法。
            }
            if (e.KeyCode == Keys.Down)
            {
                DevExpress.XtraEditors.ComboBoxEdit combobox = sender as DevExpress.XtraEditors.ComboBoxEdit;
                combobox.ShowPopup();   //按↓键的时候展开下拉列表
            }
        }
        public static void TextEdit_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                SendKeys.Send("{TAB}");
            }
        }
        public static void LookUpEdit_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                SendKeys.Send("{TAB}");
            }
            if (e.KeyCode == Keys.Down)
            {
                DevExpress.XtraEditors.LookUpEdit lookUp = sender as DevExpress.XtraEditors.LookUpEdit;
                lookUp.ShowPopup();//展开下拉列表
            }
        }
        public static void searchLookUpEdit_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                SendKeys.Send("{TAB}");
            }
        }
        public static void MemoEdit_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Down)
            {
                SendKeys.Send("{TAB}");//↓键
            }
        }
    }
