双击GridView问题

[ouyang4683]

e.Row.Attributes.Add("onDblClick", "javascript:__doPostBack('GridView1','Select$" + e.Row.RowIndex + "')");


老提示：缺少对象
e.Row.Attributes.Add("onDblClick", "javascript:__doPostBack('GridView1','Select$12')");
还是错

为什么啊

应该是js错误，检查下 id GridView1的sener和Select$(e.Row.RowIndex)

js是系统自动生成的。

好像是onDblClick（）吧

把onDblClick贴出来看看。

lz这是做什么呀 双击某一行？

缺少对象是因为你没能Select这一列,或者你把这一列给Visible = false;

[criedshy]

你要把那列设置为客户端的不可见 而不是服务端的不可见,不然在客户端就找不到__doPostBack('GridView1','Select$" + e.Row.RowIndex + "')这个方法了

我是在页面里双击的啊

这跟隐藏有什么关系。。。都看不到也点不到啊

[yangzhangyu832]

学习。。顶。。

[吕津]

有点意思。

[Jinglecat]

缺少 __doPostBack 函数 ？

放一个隐藏的Button到页面上

<asp:button runat=server style=display:none UseSubmitBehavior=false />
