using code behind model how have conditional code in aspx

[Support]

Hello:
USing the code behind model, i do not understand how to do a conditinal
space in the aspx page. For example: I have two tables, under condition 1 I
want table 1 to show and under condition 2 I want table 2 to show. Place
holders wont work for me. In the old asp environment, this was easy because
both presentation and logic were in the same file but I do not understand
how to do this.
I guess in the vb/dll, I could do a response.write but if your table a
complex it is a pain to do it that way.
Should I use DIVs and set their visibility ? (I am concerned about browser
support - this needs to work for all browsers...)
Thanks
Terry

You can conditionally set the visibility of your controls. Your table
should have a runat="server" attribute, and have an ID so you can refer
to it from your codebehind (or put it inside some container, like a
PlaceHolder). Then its just a matter of setting the Visible property.

On a side node: in 2.0 there'll be a multiview control which makes it a
more convenient to switch between views.

Use the Visible porperty. It also to tell if the control should be rendered.
If set to false no HTML code is written....

Don't call Response.Write -- that's the old way

You can just set the Visible propery of the control so that it will or won't
render to the browser. All server side controls have this property -- including
the PlaceHolder and HtmlTable controls.

This code behind is such a mess....

I am using a table as a data entry placement structure so you are suggesting
I must write at each load the table structure, the labels, the textboxes and
populate them, etc...
Dim r As HtmlTableRow
Dim c As HtmlTableCell

BUT I really would like to use an existing - completed - table structure
and render it visible or not... like using a DIV but serverside ... if I use
runat="server" it appears I must re-write this table every time ...etc....

This is a complex daqtaentry table with many fields and validation...

I am confused! sorry / Is there a way I can "Blockout" table2 ?

<table id="table1">
<tr><td>Title</td><td><asp:textbox id="tbvcENGPORTALPEOPLEtitle"
runat="server" size="40"></asp:textbox></td></tr>
<tr><td>First Name</td><td><asp:textbox id="tbvcENGPORTALPEOPLEFirstName"
runat="server" size="40"></asp:textbox></td></tr>
</table>

<table id="table2">
<tr><td>More Info</td><td><asp:textbox id="tbvcENGPORTALPEOPLEmoreinfo"
runat="server" size="40"></asp:textbox></td></tr>
<tr><td>More Infor Again</td><td><asp:textbox
id="tbvcENGPORTALPEOPLEmoreinforagain" runat="server"
size="40"></asp:textbox></td></tr>
</table>
