在angular 4中添加和编辑DevExtreme网格时自定义弹出窗口

Question

我是angular 4的新手，我使用过devExtreme网格来显示数据，并使用REST API进行了所有的CRUD操作。我有能力绑定数据到数据网格，但我想自定义的添加和编辑模板弹出，因为有文件上传控制以及查找控制与图像我需要add.Please你能帮助我在这一点上。

import { Component, OnInit } from '@angular/core';
import {DataService} from 'app/app.DataService';
@Component({
  selector: 'app-manage-category',
  templateUrl: './manage-category.component.html',
  styleUrls: ['./manage-category.component.css'],
 providers:[DataService]
})
export class ManageCategoryComponent implements OnInit {
dtCategory: Categories[];
//events: Array<string> = [];
showHeaderFilter: boolean;
showFilterRow: boolean;
title:string;
  constructor(private _dataservice:DataService) {
      this.showHeaderFilter = true;
        this.showFilterRow=true;
 
   }

  ngOnInit() {
  this._dataservice.getCategories().subscribe(categories=>{this.dtCategory=categories});

}
 logEvent(eventName) {
   if(eventName==="InitNewRow")
   {
     
   }
  }
}

interface Categories {     
    CategoryID: number; 
    CategoryIcon: string;
    CreatedBy:string;
    CreatedDate:Date;
    CategoryName:string; 
    IsActive:boolean;
}
