DEV_XAF_添加按钮

1.代码添加

using System;
using System.Linq;
using System.Text;
using DevExpress.Xpo;
using DevExpress.ExpressApp;
using System.ComponentModel;
using DevExpress.ExpressApp.DC;
using DevExpress.Data.Filtering;
using DevExpress.Persistent.Base;
using System.Collections.Generic;
using DevExpress.ExpressApp.Model;
using DevExpress.Persistent.BaseImpl;
using DevExpress.Persistent.Validation;

namespace BKYDemo.Module.BusinessObjects
{
    [DefaultClassOptions]
    //[ImageName("BO_Contact")]
    [XafDisplayName("添加按钮")]
    [DefaultProperty("姓名")]
    //[DefaultListViewOptions(MasterDetailMode.ListViewOnly, false, NewItemRowPosition.None)]
    //[Persistent("DatabaseTableName")]
    // Specify more UI options using a declarative approach (https://documentation.devexpress.com/#eXpressAppFramework/CustomDocument112701).
    public class 员工信息 : BaseObject
    { // Inherit from a different class to provide a custom primary key, concurrency and deletion behavior, etc. (https://documentation.devexpress.com/eXpressAppFramework/CustomDocument113146.aspx).
        public 员工信息(Session session)
            : base(session)
        {
        }
        public override void AfterConstruction()
        {
            base.AfterConstruction();
            // Place your initialization code here (https://documentation.devexpress.com/eXpressAppFramework/CustomDocument112834.aspx).
        }

        //添加按钮 （在类上写）
        // 添加为空的时候才可以点击 TargetObjectsCriteria = "IsNullOrEmpty([婚否])"
        //添加一次只能选择一行  SelectionDependencyType = MethodActionSelectionDependencyType.RequireSingleObject
        [Action(Caption = "标记为已婚", AutoCommit = true, ConfirmationMessage = "是否确认？", TargetObjectsCriteria = "IsNullOrEmpty([婚否])",SelectionDependencyType = MethodActionSelectionDependencyType.RequireSingleObject)]
        public void 查询客户明细() {
            婚否 = "已婚";
            IObjectSpace os = DevExpress.ExpressApp.Xpo.XPObjectSpace.FindObjectSpaceByObject(this);
            os.CommitChanges();
        }


        private string _姓名;
        public string 姓名
        {
            get { return _姓名; }
            set { SetPropertyValue("姓名", ref _姓名, value); }
        }

        private string _婚否;
        public string 婚否
        {
            get { return _婚否; }
            set { SetPropertyValue("婚否", ref _婚否, value); }
        }

    }
}

2.添加Controlers添加

找到Controlers文件夹——添加View Controller类 —— 在工具箱中拖simpleAction如下图

 

 

 结果：

 

 

 3.为空或者是未婚的时候才可以点

            }
            列表已婚.Enabled.SetItemValue("ObjectsCriteris",unKnow);

        }

            }
            os.CommitChanges();
