Write c# array to aspx html page

How do I take my C# array and write it to an HTML table header?

From what I've read you should be able to use cnippets to get the variable but it's not working...

C# code

protected void Page_Load(object sender, EventArgs e)
        {
            string[] tableHeaders = {
                "Urgency", 
                "Picker", 
                "CARD", 
                "Case Order", 
                "CR #", 
                "Patient", 
                "Age", 
                "ASA", 
                "Anes Consult", 
                "Procedure", 
                "Booking Surgeon", 
                "Operating Surgeon", 
                "Ready Date", 
                "Ready Time", 
                "NPO Since", 
                "EST Time", 
                "Current Location", 
                "Postop Need", 
                "Booked by", 
                "Special Equipment", 
                "Comments"
            };
        }

HTML Code You'll see in my document.write line I try to call the tableHeaders variable. And I use the javascript row variable as a counter. 

<thead>
  <tr>
    <script type="text/javascript">
      for (var row = 0; row <= 21; row++) {
        document.write("+<%= tableHeaders[+row+] %>+")
      }
    </script>
   </tr>
 </thead>

I shouldn't have been trying to use Java-script to do this. The following worked perfectly. 

 <%
     for (int td = 0; td <= 20; td++)
     {
         Response.Write("<td>" + tableHeaders[td] + "</td>");
     }
 %>

Assuming you want to create actual header cells for your table, you should be able to do it all within c# code behind unless you have some need to dump things into JavaScript. Add an ID to your <tr> element and a runat attribute:

<thead>
    <tr ID="headerRow" runat="server">
    </tr>
</thead>

Then in your page load you can add each header element individually:

protected void Page_Load(object sender, EventArgs e)
{
    string[] tableHeaders = { // blah blah };

    foreach(var header in tableHeaders)
    {
        var tmp = new TableHeaderCell();
        tmp.ID = "TH_" + header;
        tmp.Text = header;
        headerRow.Cells.Add(tmp);
    }
}

Then when the page renders, it should render each one out as a <th> element within your row.

You are creating a local variable in Page_Load then trying to access it from the page script. You can make it a class member instead:

(outside of Page_Load or any other method):

private string[] tableHeaders = {
    "Urgency", 
    "Picker", 
    "CARD", 
    "Case Order", 
    "CR #", 
    "Patient", 
    "Age", 
    "ASA", 
    "Anes Consult", 
    "Procedure", 
    "Booking Surgeon", 
    "Operating Surgeon", 
    "Ready Date", 
    "Ready Time", 
    "NPO Since", 
    "EST Time", 
    "Current Location", 
    "Postop Need", 
    "Booked by", 
    "Special Equipment", 
    "Comments"
};
