  1. 确保WebAPI可以正常运行并可以返回所需的数据。

  2. 检查数据网格代码以确保正确设置数据源(dataSource)。例如:

import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';
import { GridDataResult, DataStateChangeEvent } from '@progress/kendo-angular-grid';

@Component({
  selector: 'app-grid',
  templateUrl: './grid.component.html'
})
export class GridComponent implements OnInit {
  public view: Observable;
  public gridData: any[];
  public dataState: any = {
    skip: 0,
    take: 5
  };

  constructor(private http: HttpClient) { }

  ngOnInit() {
    this.setGridData();
  }

  setGridData() {
    this.view = this.http
      .get('https://example.com/api/data')
      .pipe(
        map(res => {
          this.gridData = res;
          return {
            data: res.slice(this.dataState.skip, this.dataState.take + this.dataState.skip),
            total: this.gridData.length
          };
        })
      );
  }

  public dataStateChange(state: DataStateChangeEvent): void {
    this.dataState = state;
    this.setGridData();
  }
}
  1. 确保在数据源设置中使用正确的字段名。例如:

  
  
  

  1. 确保导入所需的模块。例如:
import { GridModule } from '@progress/kendo-angular-grid';
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [GridModule, HttpClientModule],
  declarations: [GridComponent],
  bootstrap: [GridComponent]
})
export class AppModule { }
  1. 确保在app.module.ts中添加数据网格模块。例如:
import { GridModule } from '@progress/kendo-angular-grid';
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';

import
