从服务器端数据绑定时,telerik Radgrid中的分页问题

标签: asp.net data-binding gridview radgrid telerik-grid

我有两个radgrid,对于第一个radgrid,我绑定来自serverside的数据,而对于第二个radgrid,我通过sqldatasource从clientside绑定数据。  我通过clientside绑定数据的radgrid2,pagination属性工作正常,我的网格每次都刷新。  但是主要的问题是当从服务器端绑定radgrid时我的分页属性不起作用,当我从服务器端绑定数据时,我必须设置为分页工作的任何属性,任何人都可以帮助找出问题。

这是我的aspx页面代码,其中包含radgrid

我有一个类似的问题,将RadGrid.DataSource设置为Linq查询。我会告诉你一些我尝试过的事情,以及我最终要做的事情。

首先,如果

 AllowCustomPaging = True

然后覆盖默认分页。尝试将AllowPaging设置为true,或将AllowCustomPaging设置为true,但不能同时设置为true。 Telerik控件变幻莫测! :)

我也尝试在MasterTableView中设置分页,但无济于事 我还添加了AllowViewstate并确保控件已链接到RadAjaxManager

<telerik:AjaxSetting AjaxControlID="RadGrid1">
       <UpdatedControls>
             <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
       </UpdatedControls>
 </telerik:AjaxSetting>

对我来说都没有用,但试一试。

我最终使用了Listview并为内部数据设置了模板化列,并且启用了分页,这一切都运行得很好。我知道这不是一个直接的答案,但它可能会给你一些新的想法。

我刚刚意识到我的网格中有AllowPaging="true"AllowCustomPaging="true"。删除其中一个修复了该问题。
