I would like to dynamically create ASP tables using VB to dynamically populate the data and provide unique IDs and then assign it to a Literal in Passthrough mode.

How can I go about qualifying my code with quotation marks around ASP parameters and having VB.Net accept/concatinate my string properly? I know the vb is being triggered because I also have a label change.

Sample of my code:

htmlText = "<asp:TableRow ID=""TR1C" & intC.ToString() & """>"

CraneTables.Text = htmlText.ToString()

(In the ASP page)
<asp:Literal ID="CraneTables" Mode="PassThrough" EnableViewState="false" runat="server"></asp:Literal>

Open in new window

I'm not an expert in ASP, so if there is a better way for me to do this can you please provide some examples. I am trying to keep it all in the code behind because I will also be pulling in data from multiple MS SQL queries and have Create/Update/Delete tied into it.

Thank you.

This:

htmlText = "<asp:TableRow ID=""TR1C" & intC.ToString() & """>"

Open in new window

...is not going to work. You cannot create server-side controls via a string. Such controls need to be present in the markup at the time the view engine runs. Aside from that, your approach seems complicated. Why not just create a table in your code-behind?

e.g.

Code-behind

Dim t As New Table()
Dim r As New TableRow()
Dim c As New TableCell()

c.Text = "Hello World!"
r.Cells.Add(c)
t.Rows.Add(r)
t.ID = "TR1C" + i.ToString()
Me.placeholder1.Controls.Add(t)

Open in new window

Markup

<asp:Placehodler ID="placeholder1" runat="server"></asp:Placeholder>

Open in new window

This is a great way to display data and control it.
