Re: Pb: passing values between pages using NavigateUrl

Hello, Thanks for your helps, I tried NavigateUrl='<%# "GestionCommande.aspx?groupe=" & DataBinder.Eval(Container.DataItem, "groupe")%>'

a) by replacing '&' with:

nothing => errors: missing ) missing ;

'+' or ',' => error CS: 'System.Web.UI.Page' does not have a definition for 'DataItem' and no 'DataItem' extension method accepting
the first argument with 'System.Web.UI.Page' type can be found (a Using directive or assembly reference missed?)

b) by replacing <%# %> with

<%= %> => here's what I got when I click on the link

http://localhost/GDA/%3C%=%20%22OrderManagement.aspx?group=%22%20&%20DataBinder.Eval(Container.DataItem,%20%22groupe%22)%%3E

c) by replacing NavigateUrl='<%# "GestionCommande.aspx?groupe=" & DataBinder.Eval(Container.DataItem, "groupe")%>' with

NavigateUrl='<%= "GestionCommande.aspx?groupe=" + Request.Params["groupe"]%>' => here's what I got when I click on the link:

http://localhost/GDA/%3C%=%20%22OrderManagement.aspx?groupe=%22%20+%20Request.Params[%22groupe%22]%%3E

That's really strange, s.o has the same pb? Both methods cannot resolve. Here's my solution (it works for my application): I put variables into Session. Here's how it works (to people who do not knows):

page 1: Session["group"]= group;

page 2: string group=Session["group"]

Session variable is still avaible throught out the application (between pages), you can get it at anytime.

Thanks

<% ... %> operator allows you to execute a statement but it does evalute/return an expression to be expanded in your asp. That's why you get the UrlEncoded source string instead of its evaluated form.

Try <%= ... %> instead and it should work fine.

<asp:HyperLink id="DemandeurLink" runat="server"
Text="Gestion des commandes" NavigateUrl='<%= "OrderManagement.aspx?group=" + Request.Params["group"]%>'/>

If you chose to use <%# ... %> instead, then you also need to call DataBind() form your code behind.

NavigateUrl='<%#"OrderManagement.aspx?group=" & DataBinder.Eval(Container.DataItem, "group")%>'

Pb: passing values between pages using NavigateUrl

tng — Thu, 02 Jul 2009 13:00:08 GMT

Hello,

I'm not sure if I'm in the right place to post this question, here's my pb:

I have a login.aspx.cs page where I get a value & pass it in the url, like this:

Response.Redirect("Welcome.aspx?group=" + group + "&user=" + Login1.UserName.ToString(), false);

Then in the Welcome.aspx page I have 3 links: ProjectManagement, SupplierManagement, OrderManagement. Some of them can be shown or hidden, according to the group that I got from the url, as shown:

<asp:HyperLink id="DemandeurLink" runat="server"
Text="Gestion des commandes" NavigateUrl='<% "OrderManagement.aspx?group=" + Request.Params["group"]%>'/>

<asp:HyperLink id="BuyerLink" runat="server"
Text="Gestion des commandes" NavigateUrl='<% "SupplierManagement.aspx?group=" + Request.Params["group"]%>'/>

<asp:HyperLink id="AdminLink" runat="server"
Text="Gestion des commandes" NavigateUrl='<% "ProjectManagement.aspx?group=" + Request.Params["group"]%>'/>

It means that I want to transfer group variable twice: from the login page to the welcome page, and them from the welcome page to one of 3 links below. The pb is when I click on one of these 3 links, I do not have what I expected, but:

http://localhost/GDA/%3C%%20%22OrderManagement.aspx?group=%22%20+%20Request.Params[%22group%22]%%3E

What cause the pb? What have I done wrong?

I also tried (help from google):

NavigateUrl='<%#"OrderManagement.aspx?group=" & DataBinder.Eval(Container.DataItem, "group")%>'

but I got a compile error:

error CS: 'System.Web.UI.Page' does not have a definition for 'DataItem' and no 'DataItem' extension method accepting
the first argument with 'System.Web.UI.Page' type can be found (a directive or assembly reference missed?)

So, what should I do, please help!!!

Thanks,
