有关GridView中ImageButton控件后台代码弹出对话框如何写
这是我前台的 <asp:GridView> 的相关信息，其中<asp:ImageButton ID="ImageButton2" CommandName="UserUpdate" runat="server" ImageUrl="~/images/edit.PNG" CommandArgument='<%# Eval("userid") %>' /> 这句是用来转向修改界面的。
<asp:GridView ID="gvUserManage" runat="server" AllowPaging="True" Width="100%" CellPadding="1"
BorderWidth="1px" AutoGenerateColumns="False" RowStyle-HorizontalAlign="Center"

</PagerTemplate>
</asp:GridView>
这是后台代码：
#region 转发至修改页面
protected void gvUserManage_RowCommand(object sender, GridViewCommandEventArgs e)
{
///转发至修改页面
if (e.CommandName.ToString() == "UserUpdate")
{
Response.Redirect("UpdateUser.aspx?userid="+e.CommandArgument.ToString());
}
}
#endregion
现在我想弹出一个修改的对话框而不是一个新的界面，于是我将
Response.Redirect("UpdateUser.aspx?userid="+e.CommandArgument.ToString());
改为 Response.Redirect("<script type='text/javascript'>window.showModalDialog('../WebApp/System/UpdateUser.aspx? userid=' + e.CommandArgument.ToString(), 'window', 'dialogWidth:400px;DialogHeight=405px;status:no;scroll=yes;help:no')</script>");
其中WebApp是我项目里的一级文件，System是它下面的二级文件，UpdateUser是System下面的一个.aspx.
运行结果出现乱码，我估计是文件路径的问题，试了好多变还是没改过来，求解，在线等！
[解决办法]
Response.Write("<script type='text/javascript'>window.showModalDialog('../WebApp/System/UpdateUser.aspx? userid=' + e.CommandArgument.ToString(), 'window', 'dialogWidth:400px;DialogHeight=405px;status:no;scroll=yes;help:no')</script>");
