我有一个带有网格视图的ASP.Net网页。我想根据下拉列表的选择过滤网格视图数据。我在另一个页面上正常工作。问题页面上的区别在于我需要过滤的列是int而不是varchar。当我加载页面时，我收到错误消息：输入字符串格式不正确。ASP.Net SQLDataSource筛选器 - 输入字符串格式不正确
我已经粘贴下面的下拉列表和数据源的代码。这一定是一个共同的要求，所以我想我错过了明显的东西......？试图通过谷歌寻找解决方案时，其他人也有同样的问题。可以在http://www.velocityreviews.com/forums/t123088-problem-in-filterparameters.html找到非常类似的帖子，不幸的是，加文的决议对我没有帮助。
非常感谢，
Rob。
