You can do it like this. Add client of your control in one hidden field and then access it like;

C#

<asp:hiddenfield id="hdnNameTextBox" runat="server" xmlns:asp="#unknown" />

    void FormView1_DataBound(object sender, EventArgs e)
    {
      hdnNameTextBox.Value = ((TextBox)FormView1.FindControl("TextBoxId")).ClientID;
    }

Now use the hidden fields value.

Java

var id = document.getElementById('hdnNameTextBox').value;

var txt =  document.getElementById(id);
