Hi Carl

Could you have the URL's to the registration form appended with query string data ? e.g. registration.aspx?courseID=1234

Then on page load of the user control you could check for the query string data and do stuff accordingly.

Cheers

If you're .net user control is on the course detail page, then you can use the umbraco.NodeFactory.Node.GetCurrent(); to get the current node.  You can then use the 'node' object to get information about that particular course.

If the registration form is on a different page, then you can pass the node id of the node containing all the courses and iterate through them to fill your drop down list.

To do this in your usercontrol create a public property that's an int e.g. 'CoursesNodeId'.  In the macro for your usercontrol, create a macro parameter with the same name e.g.  'CoursesNodeId'.

Then your code needs to do something like:

protected void Page_Load(object sender, EventArgs e)

        {

            if (!Page.IsPostBack)

            {

                LoadCourses();

            }

        }

        private void LoadCourses()

        {

            Node coursesNode = new Node(CoursesNodeId);

            foreach (Node course in coursesNode.Children)

            {

                ddlCourses.Items.Add(new ListItem(course.Name, course.Id.ToString()));

            }

        }

        public int CoursesNodeId

        {

            get;

            set;

        }

Hope that's what your after

Thanks Nigal, Thats a good idea. I could grab the @nodeName on the net control registration page with

Request.QueryString["@nodeName"];

My concern is the course names are rather long. Is there a way to pass the @id in the quary and then use the node node factory net control to find the @nodeName or any other information related to that node?

If so, this just might be what I was looking for

Thank you

This will pass the node id: Request.QueryString["@id"];

Then you can use

Node courseNode = new Node(int.Parse(Request.QueryString["id"]))

string nodeName = courseNode.Name;

Hey Euan,

Thanks for your reply. You are very close. The only point is I don't want a drop down list on the registration form. I'm only using a manual drop down now because I don't know which course they are intrested in (I'm typing each course in)

All the courses are on a course list template with a xslt course list macro

The registration page is a net control on its own page. Currently the two do not communicate with each other.

Ah, I see.

In that case, your best bet is to do what Nigel suggested and pass the node id in the query string.  Then you can use the API as above to get the node information

Thanks Nigal and Euan,

I will try Nigal's solution tonight and update with the complete code to help others.

Hello, I'm running into another issue as I'm setting up my @id to pass.

Which is the best way to pass the ID using XSLT?

The registration form is located at http://somesite.com/register.aspx

The goal is for each course to pass its id so it looks like this http://somesite.com/register.aspx?course=1234 etc, etc

and I would catch the ID using Request.QueryString["id"]

I was trying something like this, but got stuck

          <xsl:element name=”a”>

                <xsl:attribute name=”href”>

                  <xsl:value-of select=””/>

                </xsl:attribute>

            <xsl:value-of select=”./”/>

          </xsl:element>

Assuming that the page you are linking from is the relevant course node, you could use something like

<a>

<xsl:attribute name="href">

<xsl:text>/register.aspx?id=</xsl:text>

<xsl:value-of select="$currentPage/@id"/>

</xsl:attribute>

Click here to register

</a>

Thanks Euan,

Thats the tricky part...sorta. Another issue popped up. My layout looks like this

Courses ID 1234

- Course A  ID 1020

- Course B ID 2010

- Course C ID 2014

When I click on "register now" on any course 1234 shows up (the parent)

Any Ideas?

Thank you in advance!

OK, I'm assuming what you're doing to display the courses is something like

<xsl:for-each select="$currentPage/courseNode">

<ul>

<li>

<xsl:value-of select="umbraco.GetXmlNodeById(@id)/@nodeName"/>

<a>

<xsl:attribute name="href">

<xsl:text>/register.aspx?id=</xsl:text>

<xsl:value-of select="@id"/>

</xsl:attribute>

Click here to register

</a>

</li>

</ul>

</xsl:for-each>

I've put the updated line in bold and red - if you are doing it the way I'm guessing this should fix your problem

Thanks for this blog post. You consistently write a intriguing post. Thanks!
