Why are you not saving the id's when you create the text boxes?

i create one text box, user will enter number of text boxes, that text boxes will be visible.

if i will enter "5" in that textbox, 5 textboxes will visible.user enter his information in that text boxes , that text will be save in db.

And so? What does that have to do with you saving the id's of the text boxes when you create them?

And how are we supposed to know that? How are we supposed to know what you have done when you have not shown us what you have done?

text changed event

protected void TextBox2_TextChanged(object sender, EventArgs e)
{
t1 = Convert.ToInt32(TextBox2.Text);
for (int i = 0; i < t1; i++)
{
TextBox textBox = new TextBox();
textBox.ID = "mytxt" + i;
textBox.Style[HtmlTextWriterStyle.Top] = "10px";
textBox.Style[HtmlTextWriterStyle.Left] = "50px";
pnlQuestions.Controls.Add(textBox);
TextBox txtpaper = new TextBox();
txtpaper.ID = "pap" + i;
txtpaper.Style[HtmlTextWriterStyle.Top] = "10px";
txtpaper.Style[HtmlTextWriterStyle.Left] = "50px";
pnlQuestions.Controls.Add(txtpaper);
Literal lt = new Literal();
lt.Text = "<br />";
pnlQuestions.Controls.Add(lt);
InitializeComponent();
}
}

button click

t1 = Convert.ToInt32(TextBox2.Text);
for (int i = 0; i < t1; i++)
{
string ID = "mytxt" + i;
TextBox txtbx =pnlQuestions.FindControl("mytxt" + i) as TextBox;
}

this my code

Most likely reason that you cannot find the controls again is because when you click the button, you are getting a postback and the controls do not exist anymore.
