DevExpress中SearchLookUpEdit基础用法

1.绑定数据

searchProduct.Properties.ValueMember = "ID";
searchProduct.Properties.DisplayMember = "Code";
searchProduct.Properties.DataSource = orderDatas;
searchProduct.Properties.NullText = "下拉选择工单信息";
searchProduct.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.Standard;//空时的值
searchProduct.Properties.ImmediatePopup = true; //输入值是否马上弹出窗体
searchProduct.Properties.ValidateOnEnterKey = true;  //回车确认
searchLookUpEdit1View.BestFitColumns();

2.指定选择项

SearchLookUpEdit.EditValue = ID //控件默认选择内容

3.判断是否为空

if(searchProduct.Properties.NullText == "" || searchProduct.Properties.NullText == "下拉选择产品信息")
 {
     XMessageBoxHelper.ShowError("所属产品不能为空！");
     searchProduct.Focus();
     return;
 }
