You can create and get the value of dynamically created text box in web forms using the below code

Web-forms .aspx HTML code

<asp:Panel ID="pnlTextBoxes" runat="server">
<hr />
<asp:Button ID="btnAdd" runat="server" Text="Add New" OnClick="AddTextBox" />
<asp:Button ID="btnGet" runat="server" Text="Get Values" OnClick="GetTextBoxValues" />

C# Code behind

//retain the dynamic TextBoxes across PostBacks
protected void Page_PreInit(object sender, EventArgs e)
    List<string> keys = Request.Form.AllKeys.Where(key => key.Contains("txtDynamic")).ToList();
    int i = 1;
    foreach (string key in keys)
        this.CreateTextBox("txtDynamic" + i);

protected void AddTextBox(object sender, EventArgs e)
    int index = pnlTextBoxes.Controls.OfType<TextBox>().ToList().Count + 1;
    this.CreateTextBox("txtDynamic" + index);
private void CreateTextBox(string id)
    TextBox txt = new TextBox();
    txt.ID = id;
    Literal lt = new Literal();
    lt.Text = "<br />";

//Get Value of textbox
protected void GetTextBoxValues(object sender, EventArgs e)
    string message = "";
    foreach (TextBox textBox in pnlTextBoxes.Controls.OfType<TextBox>())
        message += textBox.ID + ": " + textBox.Text + "\\n";
    ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", "alert('" + message + "');", true);

The above code Adds textbox dynamically, and get it's value
