get values from dynamically added user controls

[jburnage]

I need help in getting the values from a dynamically added user control when a user submits a form. The controls are added to a placeholder and this all works fine - but its looping through the controls that i'm having trouble with.

Its the "case 1:" statement that i need help with

cheers in advance for any help

my code is as follows.

// a Property that manages a counter stored in ViewState
protected int NumberOfSchemeC ontrols
{
get{return (int)ViewState["NumControl s"];}
set{ViewState["NumControl s"] = value;}
}

if(!Page.IsPost Back)
//Initiate the counter of dynamically added scheme controls
this.NumberOfSc hemeControls = 0;
else
//Scheme Controls must be repeatedly be created on postback
this.createSche meControls();


private void createSchemeCon trols()
{
int count = this.NumberOfSc hemeControls;

for(int i = 0; i < count; i++)
{
scheme uc = (scheme) this.Page.LoadC ontrol("scheme. ascx");
uc.ID = "ControlID_ " + i.ToString();
//Add the Controls to the container of your choice
PlaceHolder1.Co ntrols.Add(uc);
}
}

private void addSchemeContro l()
{
scheme uc = (scheme) this.Page.LoadC ontrol("scheme. ascx");
uc.ID = "ControlID_ " + NumberOfSchemeC ontrols.ToStrin g();

PlaceHolder1.Co ntrols.Add(uc);
this.NumberOfSc hemeControls++;
}


private void bntMoreSchemes_ Click(object sender, System.EventArg s e)
{
this.addSchemeC ontrol();
}


private void btnSend_Click(o bject sender, System.EventArg s e)
{
try
{
user = Opra.piano.Help erClasses.UserH elper.GetUser(U ser.Identity.Na me);
MailMessage mail = new MailMessage();
mail.To = "james.burnage@ someDomain.com" ;
mail.Cc = user.Email;
mail.Subject = "Basic search request submission";
mail.From = user.Email;
mail.BodyFormat = System.Web.Mail .MailFormat.Htm l;
string[] FormFields = new string[2];
StringBuilder tableBody = new StringBuilder(" <table>");
string mailBody;

FormFields[0] ="<strong>" "</strong>";
FormFields[1] ="<strong>" "</strong>";


for(int i = 0; i < 2; i++)
{
tableBody.Appen d("<tr><td class='title'>" + FormFields[i] + "</td><td class='response '>");
switch(i)
{

case 0:
tableBody.Appen d("<h2>Detail s here</h2>");
break;
case 1:
foreach (Control ctrl in PlaceHolder1.Co ntrols)
{

}
break;

}
}
