我是角度材料设计的新手，我想显示带有页眉和页脚的日期选择器

import {DateAdapter, MAT_DATE_FORMATS, MatDateFormats} from '@angular/material/core';
import {Subject} from 'rxjs';

  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class DatepickerCustomHeaderExample {
  exampleHeader = ExampleHeader;
}

@Component({
  selector: 'example-header',
  styles: [`
    .example-header {
      display: flex;
      align-items: center;
      padding: 0.5em;
    }

    .example-header-label {
      flex: 1;
      height: 1em;
      font-weight: 500;

我正在编写一个ASP.NET页面,它从数据库中读取数据并需要在HTML表格中显示它.我不想使用gridView.

这是我尝试使用c#的代码:

    protected void Page_Load(object sender, EventArgs e)
    {
    DataTable dt = new DataTable();
        List<UserDetails> details = new List<UserDetails>();

        using (SqlConnection con = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=Sample;Trusted_Connection=True;"))
        {
            using (SqlCommand cmd = new SqlCommand("select TOP 10 ImageFile,ProductName,Features from Product_category", con))
            {
                con.Open();
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                da.Fill(dt);
                foreach (DataRow dtrow in dt.Rows)
                {
                    UserDetails user = new UserDetails();
                    user.UserId = dtrow["ImageFile"].ToString();
                    user.UserName = dtrow["ProductName"].ToString();
                    user.Location = dtrow["Features"].ToString();
                    details.Add(user);
                }
            }
        }
        return details.ToArray();
    }
