Hello,

in my init I am adding some controls into a
placeholder. The complete procedure looks like this:

Dim iLoop As Integer = 0
Dim table As New Table
table.BackColor = System.Drawing.Color.Gainsboro
table.CellPadding = 2
table.CellSpacing = 0

Dim tr As New TableRow

For iLoop = 0 To dsHeaderLinks.Tables(0).Rows
().Count() - 1
Dim td As New TableCell
td.ID = dsHeaderLinks.Tables(0).Rows(iLoop)
("ID")

If iLoop = 0 Then
td.Attributes.Add("class", "SelectedCell")
Else
td.Attributes.Add
("class", "UnSelectedCell")
End If

Dim link As New HyperLink
link.Font.Bold = True
link.Text = "  " &
dsHeaderLinks.Tables(0).Rows(iLoop)("LinkText")
& "  "
link.NavigateUrl = "/intranet" &
dsHeaderLinks.Tables(0).Rows(iLoop)("Link") & "?Index=" &
dsHeaderLinks.Tables(0).Rows(iLoop)("ID")
link.ToolTip = IIf(IsDBNull
(dsHeaderLinks.Tables(0).Rows(iLoop)("LinkTooltip")), "",
dsHeaderLinks.Tables(0).Rows(iLoop)("LinkTooltip"))

td.Controls.Add(link)
tr.Controls.Add(td)
Next

table.Controls.Add(tr)
HeaderMenuHolder.Controls.Add(table)

Now in my pageload I need to get access to the Tablecells,
so that I can set a new class for them. What would be the
best way to do that?

Thanks
 
The best way would be to hold on to a referene to them...it'll be faster and
cleaner.

private cells as new ArrayList()

OnInit
.....
tr.Controls.Add(td)
cells.Add(td)
....
end oninit

OnLoad
for each cell as HtmlTableCell in cells
cell....
next
end onload

Hi,

why are you using Controls collection to add cells in rows?
You should use:
tr.Cells.Add(td)
instead of:
tr.Controls.Add(td)

Then, you can declare the htmltable variable at Class-Level

Public Class MyControl
Dim table As New Table
...

In this way you can access it from both OnInit and OnLoad. Then you can
iterates its cells using Rows and Cells collections, for example:
table.Rows(rowindex).Cells(cellindex)
