        <td class="GridItems"><%# DataBinder.Eval(Container.DataItem,"FirstName") %></td>

        <td class="GridItems"><%# DataBinder.Eval(Container.DataItem,"Designation") %></td>
        <td class="GridItems"><%# DataBinder.Eval(Container.DataItem,"Username") %></td>
        <td class="GridItems"><asp:ImageButton ID="updbtn"   ValidationGroup="Av" runat="server" ImageUrl="~/images/update.jpg"   CommandName="upd" CommandArgument=''<%# DataBinder.Eval(Container.DataItem,"UserId") %>'' /></td>
       </tr>
       </ItemTemplate>
       <FooterTemplate>
       </table>
       </FooterTemplate>
       </asp:Repeater>

如果我在转发器内部使用OnClientClick，则会出现异常，因为它找不到合适的会话对象

If i use OnClientClick inside repeater,it gives exception as it doesn''t find appropriate session object

推荐答案

当您第一次单击它时，它将客户端脚本绑定到弹出窗口.这就是为什么您必须再次单击它以获取弹出窗口的原因.
将upd.OnClientClick = "return PopUp()";更改为ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", "window.open(''urlhere'');", true);

When you first click it binds the client script to popup. And that is why you have to click it again to get the popup.

Change upd.OnClientClick = "return PopUp()"; to ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", "window.open(''urlhere'');", true);

您是否可以共享PopUp()js函数

can u share the PopUp()js function

2) 如果要像Bind()方法中那样填充转发器，请在更新后调用该方法.

2) If you are populating the repeater like in Bind() method call the method after updating.

private void Bind()
    {
        //connection command datatable...      
        Repeater1.DataSource = dt;
        Repeater1.DataBind();
    }
