如何使用crud操作动态创建网格视图或如何使用Gridview动态创建多个网格视图

Question

多个gridview（工作代码）的c＃代码。这将创建多个网格视图，但删除和编辑不起作用。

     GridView gv = new GridView();
               // gv.DeleteMethod("DeleteData");
                gv.ID = "_gridview" + categoryId;
                gv.AutoGenerateEditButton = true;
                gv.AutoGenerateDeleteButton = true;
                gv.DataSource = objSpearController.GetSpearSiteDetails(siteID, categoryId);
                gv.DataBind();
                GridPlaceHolder.Controls.Add(gv);
                GridPlaceHolder.Controls.Add(new LiteralControl("<br />"));
                gv.BackColor = System.Drawing.Color.FromName(resourceSet.GetString(categoryId.ToString()));
                gv.RowDeleting += new GridViewDeleteEventHandler(gv_RowDeleting);

上述代码的事件处理程序。抱歉错误。我是初学者。

       public void gv_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        GridView gv = (GridView)sender;
        try
        {
            int SiteId = int.Parse(ddlSiteName.SelectedValue);
            int result = objSpearController.deleteSbdData(SiteId);
            LoadSpearSiteNames();
            ddlCategory.SelectedIndex = 0;
        }
        catch (Exception ex)
        {
            lblError.Text = ex + "error";
        }
    }
