Specify which xml file to load when link is clicked

Question

I would like it so when a link is clicked on the homepage it would load a particular xml file into the next page (the page is called category-list.apsx).

This category list page uses the Repeater Control method to display the xml details on the page. I used the example shown here:

http://www.w3schools.com/aspnet/aspnet_repeater.asp

So at the moment the repeater script looks like:

<script runat="server"> sub Page_Load if Not Page.IsPostBack then dim mycategories=New DataSet mycategories.ReadXml(MapPath("categories.xml")) categories.DataSource=mycategories categories.DataBind() end if end sub </script>

After doing some research I did find someone with the same problem and the solution was to insert #tags as part of the link on the homepage (i.e. category-list.apsx#company1results) and then some script on the list page to pick up the correct xml file:

<script type="text/javascript"> var old_onload = window.onload; // Play it safe by respecting onload handlers set by other scripts. window.onload=function() { var categories = document.location.href.substring(document.location.href.indexOf("#")+1); loadXMLDoc('XML/'+categories+'.xml'); old_onload(); } </script>

This was from the following link:

http://www.hotscripts.com/forums/javascript/45641-solved-specify-xml-file-load-when-click-link.html

How can I get these two scripts to connect with each other?

It's easier to use a querystring instead of a hash '#', because the querystring will be send server-side, so there is no need of client-side javascript.

So when you call category-list.apsx?cat=company1results, you can use the following code to switch between xml files:

Public Sub Page_Load() If Not Page.IsPostBack Then Dim cat As String = Request.QueryString("cat") Dim mycategories As DataSet = New DataSet() mycategories.ReadXml(MapPath(cat + ".xml")) categories.DataSource = mycategories categories.DataBind() End If End Sub

Is there a reason why you dim mycategories as dynamic?

Thank you for the reply Erwin - its currently popping up the following error - Compiler Error Message: BC30002: Type 'dynamic' is not defined. Line 22: Dim mycategories As dynamic = New DataSet()

@Jason: I think it is entirely unnecessary to define mycategories as dynamic. Simply change it to DataSet: Dim mycategories As DataSet = New DataSet()

That seems to work fine now thank you! Are you happy with this update Erwin? If so could you edit your code and I will mark it as correct

@DanielHilgarth I converted C# to VB.Net and I didn't pay attention to the output, but your update is fine by me, thanks!
