Hi,

See the ASP.NET page below:

How can I do a deep clone of the HTML Table "SourceTable" in VB.NET? My intention is duplicate it.

Thanks in advance, Camarate

maybe you should just use jQuery :)

here is a sample
<html>
<head>
			<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript" ></script>

<script>
$(document).ready(function() {
	var tbl = $("#SourceTable");
	var tblCount = $("#myTables table").length;
	alert(tblCount);
});
function addTable(){
	var tbl = $("#SourceTable");
	var tblCount = $("#myTables table").length;
	var newTbl = tbl.clone();
	newTbl.id = "SourceTable"+tblCount;
	newTbl.appendTo("#myTables");
}
</script>
</head>

<div id=myTables>
        <table id="SourceTable" runat="server" border="0" cellpadding="0" cellspacing="0" style="width: 300px; height: 90px;">
            <tr>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
            </tr>
            <tr>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
                <td style="vertical-align: middle; width: 100px; height: 30px; background-color: #ccffff; text-align: center">
                    Source Table
                </td>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
            </tr>
            <tr>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
                <td style="width: 100px; height: 30px; background-color: #ccffff">
                </td>
            </tr>
        </table>
</div>

<button onClick="addTable()">add</button>

Dim str as StringBuilder = "<table id=""SourceTable"" runat=""server"" border=""0"" cellpadding=""0"" cellspacing=""0"" style=""width: 300px; height: 90px;"">"

For i = 0 To 2
      str.Append(" <tr>")
      str.Append("<td style=""width: 100px; height: 30px; background-color: #ccffff""></td>")
      str.Append("<td style=""width: 100px; height: 30px; background-color: #ccffff""></td>")
      str.Append("<td style=""width: 100px; height: 30px; background-color: #ccffff""></td>")
      str.Append(" </tr>")
Next

str.Append(" </table>")
divMain.InnerHtml = str.Tostring()
         
             
place a divMain in your aspx

whats the purpose of this cloning?

HainKurtSr. System AnalystCommented:
or maybe you cfreate a new literalControl with html = SourceTable.InnerHtml and add that one to divs control collection (give an id to div and add runat=server)

<div id=myTables runat=server>
  <table id="SourceTable" runat="server"..>...</table>
</div>

myTables.controls.add (new LiteralContrrol(SourceTable.innerHTML));

may have some syntax issues, not tested...

Hi HainKurt,

Thanks for you reply.

Although not exactly what I wanted (to do this in a VB.NET code), your solution is very simple and smart. I will use it to get my target.

In relation to my purpose of this cloning is change, depending on certain conditions, the presentation order of HTML objects on the page. To illustrate, see the code below.
