如何清除gridview中的先前值 [英] how to clear previous value in the gridview
问题描述
在Gridview中如下
房间课程房间课程
11 LGTF 21 PH1
编辑（链接按钮）编辑（链接按钮）
12 RM 22 ERS
编辑（链接按钮）编辑（链接按钮）
13 REO 23 PH2
编辑（链接按钮）编辑（链接按钮）
当我点击弹出的编辑链接按钮时课程将显示在下拉列表中。
如果用户想要更改特定房间的课程，请单击编辑（链接按钮）并在下拉列表中选择课程，点击确定。在gridview中，更改课程将在gridview中显示。
例如，11号房间LGTF在那里，如果用户想要改变路线从LGTF到PH1意味着，在21号房间已经分配了PH1课程，那个房间21路PH1将在网格视图中被清除。
我怎么能在asp.net中使用csharp。
