How to get values from dynamically created textboxes in asp.net

Question

I have created some dynamic TextBox in ASP.NET Web Forms. Please somebody tell me, how I can get the text values of corresponding textboxes and save them to database. Here is my code:

for (int i = 0; i < n; i++)
{
     MyTextBox.ID = "tb" + "" + ViewState["num"] + i;
     this.PlaceHolder1.Controls.Add(MyTextBox);
}

Use CssClass property of the asp:textbox and get by classname and postback using javascript. Values in dynamic textbox refreshes with every page load. — Polynomial Proton

That is not the way to get the values in code behind using ASP.NET. — VDWWD

You use FindControl:

    protected void Button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < n; i++)
        {
            TextBox tb = FindControl("tb" + ViewState["num"] + i) as TextBox;
            string value = tb.Text;
        }
    }
