Take one class level static variable for querystring.
And use it for manipulating it.

C#

static string Qstring = "default.aspx?";
bool ifBoth = false;
//here check whether both are selected or not and manipulate ifBoth as per selection

    if (ifBoth)
    {
        Qstring += (("cat" + valueForCategory) + ("&Area" + valueForArea));
    }
    else
    {
        if (CategoryChoosen)
        {
            Qstring += ("cat" + valueForCategory);
        }
        else if(AreaChoosen)
        {
            Qstring += ("Area" + valueForArea);
        }
    }

Hey there,

Try this:
change your a elements to this.

XML

<a id="aCat" href="default.aspx?cat=shoes" runat="server">Choose Category</a>
            <a id="aArea" href="default.aspx?area=california" runat="server">Choose Area</a>

and on Page_Load event of the page, add this code, it will add cat QueryString to the second link when first link is clicked, if its not already added.
and I suppose that default.aspx is the same page where your links exist:

C#

if (Request.QueryString["cat"] != null)
                {
                    if (!aArea.HRef.Contains("cat="))
                    {
                        aArea.HRef = aArea.HRef + "&cat=" + Request.QueryString["cat"].ToString();
                    }
                }

Hope this is what you were looking for, do let me know if it works for you.

Azee...
