ASP.NET Get html table

Question

I have a table on my ASP.net page something like this:

<table runat="server" id="resultsTable"></table>

I am dynamically adding content to the table and it works great. However, I want to get HTML tables after adding dynamic content, i.e. Something like this (formatting is not important, I just added)

<table runat="server" id="resultsTable">
  <tr>
    <td>Hello!</td>
  </tr>
  <tr>
    <td>Goodbye!</td>
  </tr>
</table>

I need the result as a string. Obviously, I could make a loop and build my own data table, but I would prefer not to, if at all possible.

    }

Answer 4

There are several ways I can think of how to do this. It would be easy to surround the table in a. Then on the vb / C # side, just call hold.innerhtml and it will return a string.

Answer 5

I used the OnLoadfollowing table to HTML string conversion in my page method :

    string html;
    using (var writer = new StringWriter())
    using (var xmlwriter = new HtmlTextWriter(writer))
    {
        this.resultsTable.RenderControl(xmlwriter);
        html = writer.ToString();
    }

Take a look at HTMLAgilityPack (several SO posts link to it.)
