using NameValueCollection how can I just get textbox contrl values? - asp.net

Question

How do I collect the values of JUST the text box controls?
Is there a way to specify this in ASP.NET 4.0?
ArrayList alAnswerList = new ArrayList();
int iCount = 0;
NameValueCollection frmCollect = Request.Form;
iCount = frmCollect.Count;
for (int i = 0; i <= iCount; i++)
{
alAnswerList.Add(frmCollect.GetValues(i));
}
I am trying to avoid hardcoding an exact index value to start getting values at.
Thanks!

Answer 1

Inside btnShowAnswers_Click, add the following code:
var answers = new List<string>();
if(dlHunt.Items.Count > 0)
{
foreach(DataListItem item in dlHunt.Items)
{
var textBox = (TextBox)item.FindControl("huntAnswerText");
answers.Add(textBox.Text);
}
}
// At this point you have your list of answers and can handle as you see fit

Answer 2

Try this:
// You might not be able access the controls directly here.
//As it might be on a master page,or Simple Page or a
//Content Page or an User Control. Either you have to use FindControl()
//or NamingContainer
foreach(Control c in Page.Controls)
{
if(c is TextBox)
{
var val = ((TextBox)c).Text; // or any other properties of textbox
}
}
