LookupEdit 的具体设置

 //单击回车按钮跳转下一个控件 this.lookUpEdit1.EnterMoveNextControl = true;  //添加一个按钮，类型选择Delete，用来删除选中项 this.lookUpEdit1.Properties.Buttons.AddRange(new DevExpress.XtraEditors.Controls.EditorButton[] { new DevExpress.XtraEditors.Controls.EditorButton(DevExpress.XtraEditors.Controls.ButtonPredefines.Combo), new DevExpress.XtraEditors.Controls.EditorButton(DevExpress.XtraEditors.Controls.ButtonPredefines.Delete, "删除", -1, true, true, false, DevExpress.XtraEditors.ImageLocation.MiddleCenter, null, new DevExpress.Utils.KeyShortcut(System.Windows.Forms.Keys.Delete), serializableAppearanceObject1, "删除选中项", "Delete", null, true)}); //在输入框按任一可见字符键时立即弹出下拉窗体 this.lookUpEdit1.Properties.ImmediatePopup = true;  this.lookUpEdit1.Properties.NullText = "[请输入……]"; //不用显示表头 this.lookUpEdit1.Properties.ShowHeader = false;  //允许选择编辑 this.lookUpEdit1.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.Standard;  this.lookUpEdit1.Properties.ButtonClick += new DevExpress.XtraEditors.Controls.ButtonPressedEventHandler(this.lookUpEdit1_Properties_ButtonClick);

下面是Delete按钮的事件，设置LookupEdit的EditValue为null就可以清除选中的数据

        private void lookUpEdit1_Properties_ButtonClick(object sender, ButtonPressedEventArgs e)        {            if (e.Button.Kind== ButtonPredefines.Delete)                lookUpCompanyName.EditValue = null;        }

最后给lookUpEdit1的数据源Properties.DataSource 赋值就行了。
