Get text from a <th> using c#

Question

Hi Everyone, I need to extract some text from a HTML table

I tried using

tblGridHeader.Rows[0].InnerText.ToString()

But I'm getting the error of

"HTMLTableRow" does not support InnerText property.

I also tried InnerHTML, and still no go.

I did try using the cells property, but I'm getting an error of

Specified argument was out of the range of valid values.

Note: I just tried the cells property on a static table and it worked. So I guess it's something to do with my table being dynamically populated?

Code from visual studio editor:

<div id="divGridHeader" runat="Server" style="width:771px; text-align:left; overflow:hidden; float:left">
            <table cellpadding="0" cellspacing="0" border="0" id="tblGridHeader" runat="Server">
                <tr id="trMonth" runat="Server" class="fixedHeader">
                </tr>   
                <tr id="trDaysOfWeek" runat="Server" class="fixedHeader">                    
                </tr>   
                <tr id="trDaysInMonth" runat="Server" class="fixedHeader">                    
                </tr>
                <tr id="trFteLimit" runat="Server" class="fixedHeader" style="color:Black">                    
                </tr>                                             
            </table>
        </div> 

Code from browser:

<div id="ctl00_cphWorkforceScheduler_divGridHeader" style="overflow: hidden; width: 771px; text-align: left; float: left;">
<table id="ctl00_cphWorkforceScheduler_tblGridHeader" cellspacing="0" cellpadding="0" border="0" width="1085">

Etc, etc. I didn't paste everything since there's a lot of tags. Please assume that HTML is well formed.

Answer 1

Doesn't look like it's supported:

http://msdn.microsoft.com/en-us/library/system.web.ui.htmlcontrols.htmltablerow.innertext%28v=VS.71%29.aspx

Have you tried reading each of the row's cells?

something like this maybe?

string rowData;
foreach(HTMLTableCell c in tblGridHeader.Rows[0].Cells)
{
   rowData += c.InnerHtml; //or c.InnerText
}

Answer 2

I'm not a web guy, but a quick trip to MSDN revealed the HTMLTableRow.Cells property.

Answer 3

HTMLTableRow controls can't contain text, they can only contain other controls. What are you trying to do exactly? Chances are you should be looking at the Controls or Cells collection of HTMLTableRow, and then inspect the text (or further child controls) of its children.

Answer 4

Try something like

tblGridHeader.Rows[0].Cells[0].InnerText

Assuming you want the textual content from the row's first cell.

Answer 5

Try tblGridHeader.Rows[0].Cells[0].InnerText;

Answer 6

If you have runat="server" to the TD,you can read it in the codebehind

 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="MyProject.UI" %>
 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head runat="server">
 <title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
  <table>
    <tr>
      <td id="tdHere" runat="server">This is my content</td>
    </tr>
    <tr>
      <td>
          <asp:Button ID="btnPost" runat="server" Text="Post" onclick="btnPost_Click" />
          <asp:Label ID="lblMessage" runat="server" Text=""></asp:Label>
      </td>
    </tr>
  </table>
</div>
</form>
</body>  
</html>

and im codebehind

using System;

namespace MyProject.UI
{
  public partial class test : System.Web.UI.Page
  {
     protected void Page_Load(object sender, EventArgs e)
     {
     }

     protected void btnPost_Click(object sender, EventArgs e)
     {
        lblMessage.Text = tdHere.InnerHtml;
     }
  }
}

This is from a working example which i tested
