Question : Asp.Net I am having problem trying to access a page & passing it querystring value.

I have a Link Button in a gridview column 'update Images" see picture.
the template code is;
          <asp:TemplateField HeaderText="Update Images"  ItemStyle-HorizontalAlign="Center" HeaderStyle-ForeColor="Blue" ControlStyle-Width="20">
           <ItemTemplate>
          <asp:Linkbutton ID="lbkPAssID"  OnClientClick='<%# "popup(""Update.aspx?" & DataBinder.Eval(Container.DataItem, "Id") & ""","""");return false;" %>' runat="server" Text='<%# Bind("Id") %>' />
          </ItemTemplate>
          </asp:TemplateField>
---------------------------------------------------
the Update.aspx  is at the same level as GridView page.
But it does not come up into view?

I do not know? what is wrong I really do not need the popup...

what I do need ..is to bring up the update.aspx page and to be able to pass the query string (id) value to its code behind page....

Answer : Asp.Net I am having problem trying to access a page & passing it querystring value.

In order to use the "header()" function in line 26 below, the PHP code Must come first with not even a space before it.  Even a space before it will be sent to the browser and then headers Can't be sent.  "$headers" is a variable to hold the 'header' info for the email message.  The "header" from the "header()" function is the one that the server sends to the browser to tell it what is coming.  'header' in both cases refers to something Before the actual message or information.
