Dynamic Table Question

[Stan Sainte-Rose]

Hi,

I use this bit of code to generate dynamic tables in the page load section
....
Dim ntable as New Table
For i = 1993 To 2008
ntable = New Table
ntable.ID = "Q" + i.ToString
....
....
Next

How to use the properties of each table ?
I would like to set visible and not visible some of them using their ID.

Stan, I'd add the tables to a hashtable so that you can access them back
that way:

Dim tables as HashTable(15)
for i = 1993 to 2008
dim table as new Table()
...
Controls.Add(table)
tables.Add(i, table)
next

you can then access the table by the year:

dim table as Table = ctype(tables(1999), Table)
table.visible = false

Hi Karl
It seems the Dim tables as HashTable(15) is not correct..
:(

Maybe I have to reconsider my code.

Here s what I want to do (I works fine with ASP and I m trying to do it with
asp.net)

I need to load 16 tables, and hide 15 of them.
I have a another table where I display the years between 1993 to 2008
When I choose one year, I would like to hide all the table and just display
the table regarding the year.
Within asp, I m using Span and a javascript for hiding/showing the right
table.
Any help ?

Of course all the tables are dynamic and their content come from a database.
I don't have problems with the ado.net part..

Can you do this while inside the for loop?

Otherwise you can do ((Table)container.FindControl("Q" + i)).Visible =
false;. Where container is the object you added the table controls to. But I'm not sure if the container controls will be available immediately after
adding them.

Oopps..forgot the new
Try:
Dim tables as new Hashtable(15)

or, if you don't have System.Collections imported, try:
Dim tables As New System.Collections.Hashtable(15)

What ryan says about using FindControl will also work, but you should get
better performance this way, and you'll need to do less error checking.

Hi again

Stupid question...
Your procedure works fine..

But I have a problem..
When I look at the html source from the browser, the table is out the <Form>
tag.
How can I add the table between <Form> and </Form> knowing that my table has
input textbox and a submit button

Or, is there an elegant method to do it ?

When you did Controls.Add(table), you were accessing the Page's Control
property and adding the table to it Instead, you want to add the tables to
the Controls() property of the form, or a placeholder inside the form.

Not sure if you are using vs.net or not, but you should be able to to
Form1.Controls.Add(table) where Form1 is the ID of the form.

Thanks Karl,

Yes I m using VS.Net
In fact, I ve used a Panel control and I ve added the Table like this
Panel1.Controls.Add(tableau)
So, I will try yours..

However, I still have a little problem.
here's my code.
I would like to use the Page.Ispostback to avoid to reload the database and
I would like to update it when I click on the button.
If you have time to look at the code and tell me where I can add the
Ispostback command.
When the button is pressed and the database is update I would like to change
the button text to "Updated".
I think I will be able to change it to Update when one textbox will be
modified.
As I said, I m from ASP ... so.... :-)

Here's the code..
