I have many textboxes that are created dynamically as child controls of my
custom control.

I know that I must recreate them after each postback and also know that I
can use the ViewState property to save the state of my controls.

What I dont know is when to save the values into viewstate. I want to save
the text in the textboxes. Since it is the user that enters the text into
those, I need some event like OnJustBeforePostBack to save the latest values
in the textboxes.

Any help will be appreciated.
Thanks in advance...

Whenever a event takes place, i.e when user presses the submit button, you
should store the values of your textboxes to the viewstate. I think that
should be safe enough...

I guess that will not be enough because the OnClick event handler of the
button is executed AFTER the postback so my dynamic control is already gone
and recreated and so its value is already wiped out.

In my situation there is no DB. I store the info that is used to create the
TextBox also in the ViewState.
After reading the article I tried something. I put the following code...

protected override void OnLoad(EventArgs e)

{

base.OnLoad (e);

TrialCtrl= new TextBox();

this.Controls.Add( TryCtrl );

TrialCtrl.ID = "trialctrl";

}



....into my class as an OnLoad event handler and it worked and also didn't
work. What worked is that the value that the user enters into the TextBox
survives the first PostBack, but not the others. After the second and
following postbacks the text is lost again. ... makes no sense ?!?? Any idea
why this happens ?

the article talk about creating the control in the OnLoad event handler. And
since the OnLoad event handler runs after the LoadViewState stage, I can
have my data in the viewstate that will be used to create the controls.
If I can get the code below run as it should run, I guess creating the
controls in the OnLoad event handler will solve my problem...

I am afraid not, as I said earlier, the value in the textbox(TrialCtrl)
survives the first PostBack but not the second one or the ones after that...
After the second postback the text in the textbox is gone and any other
thing you write there after that stage doesn't persist through postbacks any
more.

I made a simple aspx page an put this in my onload
TrialCtrl= new TextBox();
form.Controls.Add( TrialCtrl );
TrialCtrl.ID = "trialctrl";
with public TextBox TrialCtrl; declared.
It works good for me... the values stays there after every postback...
I think they way you are overloading and inheritting has some problems..
You were saying you are overloading right?
Lets look into that.. cause the above code i showed u works perfectly fine...

you are right. It works well on a clean page. Something I do is probaby
making it fail. I will try to figure out what it is and get back to you.
