Question

我有一个简单的asp.net gridview，其中AllowSorting设置为true。这是我在其他网页中多次使用的代码，没有任何问题。

在这种情况下，当我单击希望进行排序的列标题时，我什么也没得到。我在事件方法中设置了一个断点，但从未达到过该断点。我检查了属性事件，并正确设置了onSorting事件。我看不到任何明显的错误，其他任何人以前都遇到过这个问题吗？

protected void inputGrid_Sorting3(object sender, GridViewSortEventArgs e)
{

}

当我在inputGrid_Sorting3方法的顶部括号中设置一个断点时，当我单击可排序列a之一顶部的标题时，我再也找不到它。

好的，这就是问题所在。当您单击标题以对列进行排序时，首先到达代码页中的row命令方法，然后再到达sort方法。行命令代码被炸断并停止流向sort方法。我不知道在尝试对网格进行排序时会触发行命令事件。我暂时从.aspx页面中取出了更新面板代码，然后看到调试转到了行命令方法而不是sort方法。我在行命令方法代码周围放置了一个“ if”条件，以便它可以传递到sort方法。现在可以了。

单击列标题时，不执行ASP.net Gridview“ onSorting”事件
