双击GridView问题

Question

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

Answer 1

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

Answer 2

好像是onDblClick（）吧把onDblClick贴出来看看。

Answer 3

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

Answer 4

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

Asp.net 2.0 GridView的几个事件(如实现: 行的双击/单击/捕捉键盘按键/鼠标悬浮/移出效果)(示例代码下载):

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 />
