请问前辈们:我有一个 DataGridview 里面假设有 6笔资料 3攔  A  B  C
1
2
3
4
5
6我要如何做到用鼠标将这6笔资料任意上下移动对调呢?   
那里有范例可以看呢?感谢~

Answer 1

              A  B  C
[index0]   1  1  1
[index1]   2  2  2
[index2]   3  3  3
[index3]   4  4  4
[index4]   5  5  5 想要的效果,假设滑鼠点击[index0]左键不放,移动到[index4]才放开,资料应该变成如下：              A  B  C
[index0]   2  2  2
[index1]   3  3  3
[index2]   4  4  4
[index3]   5  5  5  
[index4]   1  1  1在ListBox 我可以作到,利用复制>删除>贴上
可是DataGridview有好几栏,搞不懂～求救阿！

Answer 2

你的datagridview的数据是绑定的么？是的话，先处理绑定的数据源，对换后再绑定

Answer 3

DataGridview 的事件搞不定阿～有没有参考范例
