推荐答案

^ ]和链接2 [

Link1[^]and Link2[^] might help you to solve your problem.

尝试 ^ ]:
1.将Gridview数据绑定置于!IsPostback条件. 2.将gridview的Viewstate设置为false


如果仍然无法解决，请看一下类似的讨论: http://www.dotnetspider.com /forum/162893-Gridview-problem.aspx [ ^ ]

它说:如果Columns集合包含不支持回调的列(例如TemplateField)，则会引发NotSupportedException异常.

知识库在这里: GridView.EnableSortingAndPagingCallbacks属性 [ ^ ]

Try couple of things[^]:
1. Put the Gridview data binding in !IsPostback condition.
2. Set Viewstate as false for the gridview


If this does not resolve then, have a look at this similar discussion: http://www.dotnetspider.com/forum/162893-Gridview-problem.aspx[^]

It says: If the Columns collection contains a column that does not support callbacks, such as TemplateField, a NotSupportedException exception is raised.

Knowledgebase is here: GridView.EnableSortingAndPagingCallbacks Property [^]
