Request.QueryString help needed

[William_firefold]

I have a conlib on the frontpage which loads products 200 at a time. It uses most of the code from the "featured products" conlib with minor adjustments:

Code: Select all

    protected void Page_Load(object sender, EventArgs e)
    {
        _GlobalDisablePurchase = Token.Instance.Store.Settings.ProductPurchasingDisabled;
        if (!string.IsNullOrEmpty(this.Caption)) CaptionLabel.Text = this.Caption;
        ProductList.RepeatColumns = this.Columns;
	pager=AlwaysConvert.ToInt(Request.QueryString["p"]);////////////////////
        ProductList.DataSource = ProductDataSource.LoadForStore(200,200* pager);//////////////////////
        ProductList.DataBind();
    }

I am having trouble figuring out how to make a link at the bottom of the page with http://_________/?p+1 (ie the next page) in the href field.

Code: Select all

<asp:HyperLink ID="nextlink" runat="server" NavigateUrl='<%# getnextpageurl()%>'>Next</asp:HyperLink>

wasnt working for me for some reason.
Anyone know how to do this? Maybe Im just not formatting my hyperlink properly. Any advice appreciated.

Your hyperlink markup looks correct. Where's the code-behind for the getnextpageurl() function?

Should it be <%= getnextpageurl()%> instead of <%# getnextpageurl()%>?

They both might work (or not work) if something is calling DataBind on the page, otherwise the %# syntax will never be resolved.

This is the function I am trying to create:

Code: Select all

protected string getnextpageurl()
    {
	int pager=AlwaysConvert.ToInt(Request.QueryString["p"]);
        return "http://new.website.com/?p="+(pager+1).ToString();
    }

When i used <%= getnextpageurl()%>
It set the link address to this : http://new.website.com/ConLib/custom/<%= getnextpageurl() %>
When I use <%# getnextpageurl()%> the link has no address at all.

Hmmm I'm not sure the server-side hyperlink control supports substitution on the NavigateUrl.

Try leaving the NavigateUrl blank in the HTML and assigning it the correct value during Page_Load()

Code: Select all

.
.
.
int pager=AlwaysConvert.ToInt(Request.QueryString["p"]);
if (pager > 0)
   nextlink.NavigateUrl = "http://new.website.com/?p="+(pager+1).ToString();
else
   nextlink.Visible = false;
.
.

That fixed it.
Thanks Joe.
