GridLookUpEdit 简单应用

在属性列表中 Properties  -> view  即可打开设计器进行编辑

后台代码：

 DataTable dtt = stu.StuGetFind(sxml, 1, 50).Tables[0];
            DataView dv = new DataView(dtt);
            dtt = dv.ToTable(true, new string[] { "Stu_ID", "Stu_Number", "Stu_Name" });
            //绑定
            gridlup.Properties.DataSource = dtt;
            gridlup.Properties.ValueMember = "Stu_ID";
            gridlup.Properties.DisplayMember = "Stu_Name";

            this.gridlup.Properties.View.OptionsBehavior.AutoPopulateColumns = false;
            //默认值
            this.gridlup.Properties.NullText = "------请选择------";
            //文本居中对齐
            this.gridlup.Properties.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
            this.gridlup.Properties.AllowNullInput = DevExpress.Utils.DefaultBoolean.True;
            this.gridlup.Properties.View.BestFitColumns();

            //显示不显示grid上第一个空行,也是用于检索的应用
            this.gridlup.Properties.View.OptionsView.ShowAutoFilterRow = true;

            //以下两行是为了更好的用户体验
            this.gridlup.Properties.AutoComplete = false;
            this.gridlup.Properties.ImmediatePopup = true;
            this.gridlup.Properties.PopupFilterMode = DevExpress.XtraEditors.PopupFilterMode.Contains;
            //是否可以输入内容进行检索（还是只能使用选择输入）
            this.gridlup.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.Standard;
            //是否显示底部
            this.gridlup.Properties.ShowFooter = false;
