解决方案

  on  rowdatabound事件注册您的控件  scriptmanager 
 
 LinkBut​​ton lb1 = e.Row.FindControl（  lnkbtnPhotoaddupload）< span class =code-keyword> as  LinkBut​​ton; 
 ScriptManager.GetCurrent（this）.RegisterPostBackControl（lb1）; 
 
  as   此和保持简单的scriptmanager 和把所有代码在 updatepanel 

Insted of

简单的scriptmanager使用

 <   asp：ToolkitScriptManager     ID   =  ToolkitScriptManager1    runat   =  server >  
 <   / asp：ToolkitScriptManage r  >  

现在可以使用

                                          </asp:UpdatePanel>

解决方案

on rowdatabound event register your control to scriptmanager

LinkButton lb1 = e.Row.FindControl("lnkbtnPhotoaddupload") as LinkButton;
                ScriptManager.GetCurrent(this).RegisterPostBackControl(lb1);

as like this and keep simple scriptmanager and put all the code in the updatepanel

Insted of
simple scriptmanager use

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
                </asp:ToolkitScriptManager>

it will work now
