There are two ways to bind GridView data: one is automatic binding, and the other is manual binding. Automatic binding is not mentioned here, mainly explaining the steps and methods of manual binding
First, add the GridView object to the foreground page, and then go to the background
   Add a data source
   this.gvShowTenementsInfo.DataSource = tenementService.Select();
   Bind data sources
   this.gvShowTenementsInfo.DataBind();
Perform background data binding
After that, go to the source interface of the front desk page
Edit between <asp:GridView ID="gvShowTenementsInfo" runat="server"> and </asp:GridView> to manually add the columns that need to be showcased.
//这里是展示的集合
<Columns>
The HeaderText of the binding display data displays the header description field, and the DataField after it is used to bind the specific data source and display the data
      <asp:BoundField HeaderText="Household Name" DataField="tenName" />
  Here, ItemStyle-HorizontalAlign selects the arrangement style within the specific data column, such as centering, which needs to be manually added to each row
      <asp:TemplateField HeaderText="Whether to edit" ItemStyle-HorizontalAlign="Center">
         <ItemTemplate>
Here is the setting method in the template page, binding as many columns as you need
         <asp:Label ID="txtShow" runat="server" Text='<%# eval_r("tenName") %>' />
         </ItemTemplate>
      </asp:TemplateField>
      <asp:TemplateField HeaderText="whether to edit" >
         <ItemTemplate>
            Here is passing the object ID to be modified to the next page (Modify update page)
            <a href='UpdateTenementTypeInfo.aspx? id=<%# eval_r("tenId") %>'> edit</a>
         </ItemTemplate>
      </asp:TemplateField>
      </Columns>
