我可以创建asp:PostBackTrigger吗?因为这是我的要求。附加信息。我使用syncfusion(ej1不是ej2)网格。这里我只有div块(multigrid)。所有元素都是动态创建的。因为这是我们的要求。我们通过Example1.json创建datatable。
我的aspx代码:

<form id="form1" runat="server">
     <asp:ScriptManager ID="scritPANEID" runat="server"></asp:ScriptManager>
    <div>
          <asp:UpdatePanel runat="server" ID="multigridupdate" UpdateMode="Conditional">
        <ContentTemplate>
            <div runat="server" id="multigrid">
            </div>
        </ContentTemplate>
    </asp:UpdatePanel>
    </div>
</form>

字符串
我后面的代码是:

public static String root_path = AppDomain.CurrentDomain.BaseDirectory;
public static String rootUrl = "http://localhost:52733/";
public static DataTable dataTable = new DataTable();
public static string linkColName = "PARTY_ID";
Grid Data_Grids = new Grid();
protected void Page_Load(object sender, EventArgs e)
{
    
    string dt = File.ReadAllText(root_path + @"DataSet\Example1.json");
    DataTable datatab = UseNewtonsoftJson(dt);
    BindDataSource();
    
}
public static DataTable UseNewtonsoftJson(string sampleJson)
{

    if (string.IsNullOrWhiteSpace(sampleJson))
    {
        return dataTable;
    }
    dataTable = JsonConvert.DeserializeObject<DataTable>(sampleJson);
    return dataTable;
}
public void BindDataSource()
{
    Data_Grids.ID = "GridSample";
    Data_Grids.EditSettings.AllowEditing = true;
    Data_Grids.EditSettings.EditMode = Syncfusion.JavaScript.EditMode.Batch;
    Data_Grids.ToolbarSettings.ShowToolbar = true;
    Data_Grids.ToolbarSettings.ToolbarItems = new List<string> { "update", "cancel", "excelExport", "pdfExport" };
    Data_Grids.DataSource = dataTable;
    Data_Grids.ServerPdfExporting += FlatGrid_ServerPdfExporting;
    Data_Grids.ServerExcelExporting += FlatGrid_ServerExcelExporting;
    Data_Grids.DataBind();
    multigrid.Controls.Add(Data_Grids);
    multigridupdate.Update();
}


这里我想动态地创建触发器,因为

您可以通过使用RegisterAsyncPostBackControl方法来实现这一点。
参考下面的代码示例,

protected void Page_Load(object sender, EventArgs e)
  {
   ScriptManager scriptManager = ScriptManager.GetCurrent(this);
   if (scriptManager != null && Data_Grids != null)
   {
     //here register post back control id
     scriptManager.RegisterAsyncPostBackControl(Data_Grids);
   }
 BindSource();       
 }
