HT retrieve values in html table from codebehind

[xzzy]

I have hit a wall with not being able to enumerate the items collection in a
table row.

given:

<table runat=server id=table1>
<tr>
<td id=AAA>HowToReferenceThisValue</td>

etc...

from code behind, how can I iterate thru / parse the html table to get AAA's
text => 'HowToReferenceThisValue'

HtmlTableCell cell = table1.Controls[0].Controls[0] as HtmlTableCell;

cell.InnerHtml would evaluate to 'HowToReferenceThisValue'
cell.ID would evaluate to server side id (AAA here)
cell.ClientID would evaluate to client-side id (which may be different
than server side depending on nesting level)

To access some html attribute other than id, use
cell.Attributes["NameOfAttribute"]

Iteration via IEnumerable would be like following (above mentioned
properties can be acessed after casting to HtmlTableRow or
HtmlTableCell if needed)

foreach (Control row in table1.Controls)
{
foreach (Control cell in control.Controls)
{
....
}
}

HtmlTableCell cell = table1.Controls[0].Controls[0] as HtmlTableCell;

cell.InnerHtml would evaluate to 'HowToReferenceThisValue'

++++++++++++++++++++++++++++++++++++++++++++++++++
Problem:
cell.InnerHtml is not a property of cell

further,
table1.Controls[0].Controls[0]
( System.Web.UI.HtmlControls.HtmlTableCell )
only lists the attributes, not the item

as far as I know, the items collection of
System.Web.UI.HtmlControls.HtmlTableCell is not enumerable

Problem:
cell.InnerHtml is not a property of cell

http://msdn.microsoft.com/library/d...lshtmlcontainercontrolclassinnerhtmltopic.asp

And HtmlTableCell inherits from HtmlContainerControl.
So yes, InnerHtml is a property of cell (HtmlTableCell to which I had
cast variable 'cell').

further,
table1.Controls[0].Controls[0]
( System.Web.UI.HtmlControls.HtmlTableCell )
only lists the attributes, not the item

Attributes is an AttributesCollection
http://msdn.microsoft.com/library/d...mlcontrolshtmlcontrolclassattributestopic.asp
which implements Item
http://msdn.microsoft.com/library/d...fsystemwebuiattributecollectionclasstopic.asp
So yes, you can use Item (on Attributes of course).

Problem:
as far as I know, the items collection of
System.Web.UI.HtmlControls.HtmlTableCell is not enumerable

Problem
1) HtmlTableCell does not have items collection (as you yourself said
few lines ago).
2) Whichever object has Items, that is enumerable, for the type of
unit of items.
3) I had enumerated Controls collections (not Items), which is, yes,
also enumerable

Why don't you please compile the code first and then comment.
I have compiled it and everything works as expected.
