jqgrid不加載所有行

Question

我使用了以下內容：ASP .Net 2008 3.5 Webforms/Teradata Database。 使用的瀏覽器：IE 9，火狐

我能夠加載多達1700行，但不是整個2000+的記錄。 沒有錯誤返回請幫我解決這個問題。請指教，如果我錯過了任何低於參考和代碼：

我想你有純粹的服務器端問題。您使用返回JSON數據的WebMethod。您可以通過在web.config的相應位置添加諸如jsonSerialization maxJsonLength="50000000"/>之類的內容來增加限制。有關更多詳情，請參閱the answer。

我建議你另外在jqGrid中包含loadError回調以查看錯誤，例如「使用JSON JavaScriptSerializer進行序列化或反序列化時出錯」，他的字符串長度超過了maxJsonLength屬性設置的值。請參閱the old answer以瞭解使用詳情loadError回撥。
