I have one form for filling details and in this form i have one radio button...On selectedindexchange, if value is No then nothing happen and if value is Yes then i want to show a small form(name2) to user.

<table>
<tr>
<td>
Are you known by any other names or aliases?*: 
<asp:RadioButtonList ID="RadioButtonList1" runat="server"    RepeatDirection="Horizontal"                          onselectedindexchanged="RadioButtonList1_SelectedIndexChanged">
<asp:ListItem Value="Yes">Yes</asp:ListItem>
<asp:ListItem Value="No" Selected="True">No</asp:ListItem>
</asp:RadioButtonList>
</td>
</tr>
<tr id="name2" style="visibility:hidden">
<td>
Other names or aliases?*: 
<asp:TextBox ID="TextBox3" CssClass="textboxhalf" runat="server"></asp:TextBox>
</td>
</tr>
</table>

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (RadioButtonList1.SelectedValue == "1")
        {
            TextBox3.Visible = true;
        }
        else
        {
            
            TextBox3.Visible = false;
        }
    }

In code behind i able to access this textbox3...so i can make it visible or hide but i cannot access table row id(name2). I want to show/hide whole table row with id name2. Is that possible by only C#?
