Display different type of controls from code behind in C#

[bernie77]

Originally, I have the a panel with a drop down list and a radio button list (2 controls). Now user requests the capability to dynamically show the second control depending on user selection in the first control (drop down list). Sometimes the 2nd control can be a radiobuttonlist , sometimes the 2nd control can be another dropdownlist. How can I use code behind (in C#) to display the appropriate control at proper place of the panel?

Any suggestion is welcomed!

<asp:Panel ID="plMyPanel" runat="server">
<table border="0" cellpadding="0" width = "750px" id="table1" runat="server">
<tr>
<td align="right" style="width:20 %"><asp:Labe l ID ="lblOption1 " runat="server" Font-Bold="True" Width="83px"></asp:Label></td>
<td align="left" style="width: 51%"> <asp:DropDownLi st ID="ddlOption1 " Width = "410px" runat="server" CausesValidatio n="true"> </td>
<td style="width: 30%">&nbsp;</td>
</tr>
<tr>
<td valign="top" align="right" style="width:20 %; height: 34px;"><asp:Lab el ID ="lblOption2 " runat="server" Font-Bold="true"></asp:Label></td>
<td align="left" style="width:51 %">

you have to create control dynamically and add it to your panel.........a nd its easy enough....

 DropDownlist myddl; 
myddl=New DropDownlist();
Panel1.Controls.Add(myddl);
