Hi
in the submit button click use the following code to retrieve texts from dynamically created textboxes

C#

protected void btnSubmit_Click(object sender, EventArgs e)
{
    TextBox txt;

    foreach (Control c in Panel1.Controls)
    {
        if (c.GetType() == typeof(TextBox))
        {
            txt = (TextBox)c;
            String str = txt.Text;
        }
    }

}

Hi,

Assign unique ID for each Textbox control.... for unique id use GUID generator

Please store the (dynamic) id of text box in a List<string> and then access the dynamically created text-box by its name...

Thanks,
Ullas Krishnan
