GridView点击更新按钮两次才会触发

我的GridView中一列命令列,编辑更新,点击编辑按钮后,会正常转为编辑状态,但是再点击更新按钮时,第一次点击,此行中所有输入框中的内容会清空,而且不会触发RowUpdating事件,第二次点击时才会触发RowUpdating事件.

GridView中有两列是模板列,数据绑定也能正常显示.

请问这种情况是什么原因呢

第一次点击更新按钮仅会触发PageLoad事件,第二次点击会触发PageLoad事件和RowUpdating事件

#4

第二次只需要在哪个事件触发

#5

奇怪了,我在另一个页面中又新建了一个不同的,还是同样的情况,是不是数据源的问题?

#6

自己顶一下

貌似是数据没有及时更新释放

释放?怎么释放呢?你的意思是数据连接没有关闭?

LZ是用的MULTVIEW控件？

#10

Command指令？Update和Edit？

#11

刚在vs2010中试了一下没有问题

确认父控件的ID 是否明确

#12

没遇到过这种情况。。。。

用的是GridView啊

是的,点击编辑按钮之后,进入编辑模式,显示更新和取消按钮,点击更新按钮就会有异常
