它没有将数据绑定到gridview，有人可以告诉我解决方案吗?

it is not binding the data to gridview can any one tell me the solution

推荐答案

如果它没有绑定，那么就有可能没有查询结果中的数据.

如果没有，请提供完整的错误消息，以便我们轻松识别.

谢谢.

If it''s not binding then there may be chance that There''s no data in Query result.

If not then provide full error message so that It can be easy for us to identify.

Thanks.
