How to add an anchor<a> dinamically to an object in C#?

HI experts;

I have a WebUsercontrol (Num1.ascx) that contains a placeholder(MyPlaceholder).
This placeholder will contain a WebUser control(Num2.ascx) loading it up dinamically using C#.

The Num2.ascx contain 2 controls. One is a Label and the other one is a Drop Down List.
The information for this control are loaded from database(this part is done).

What I am trying to do:

I want to add dinamically an anchor <a> to Num2.ascx through the codebehind in Num1.ascx.
This is the anchor:
<a id="informationLinkPass" href="javascript:OpenDiv('Div2',
'ctl00_ctl00_ContentPlaceHolder1_MainContent_txtPassword');"><img alt="Click for Information" title="Click for Information" src="images/common/InformationIconTransparent.png"/></a>

What I have so far:

I created an object(object1) in Num1.ascx that will load  the Num2.ascx dinamically :
      Num2 object1= (Num2)Page.LoadControl(@"~/Controls/Num2.ascx");

It is in this object "object1"  where  I need to add the element anchor<a>. Later on I will add this object to my placeholder in Num1.ascx, so it can be display in the page :
 - MyPlaceholder.Controls.Add(object1);

What "object1" need to have after this operation are the following controls::
- Label
- Drop Down List
- Anchor (new control add it in dinamycally with some properties)

Could you give me an example using my code how can I add the anchor dinamically to this object?
Thank you




Num1.ascx:
        <div id="re1">
            <ul class="re2">
                <asp:PlaceHolder ID="MyPlaceholder" runat="server"></asp:PlaceHolder>
            </ul>
        </div>
 
Num2.ascx:
        <li>
             <asp:Label ID="lblQuestion" runat="server" Text="Question?"></asp:Label>    
             <p><asp:DropDownList ID="ddlAnswers" runat="server"></asp:DropDownList></p>    
        </li>

well, maybe that won't work for you... it depends which version of .Net you're using.

HI I am using c#  net2.0:
    HtmlAnchor NewAnchorControl = new HtmlAnchor();
                    NewAnchorControl.Name = "informationLinkWork";
                    NewAnchorControl.HRef = "javascript:OpenDiv('Div2',   'ctl00_ctl00_ContentPlaceHolder1_MainContent_txtPassword');";

Am I going in the right path? How can I add <img> to an anchor?
<img alt="Click for Information" title="Click for Information" src="images/common/InformationIconTransparent.png"/>

Thanks

I'm not a pro with HTML and ASP, but I think the following will work, though it may be a work-around to an "official" way of doing something. I suggest using the InnerText property, as shown in the following code snippet.

Also, the word you're looking for is spelled dynamically, not dinamically. www.dictionary.com, spelling is essential for professionalism :)
anchorName.InnerText = "<img src="source" alt="alt" title="title">";

Whoops, forgot a couple things. The code snippet should be as follows, instead
anchorName.InnerText = "<img src=\"SourcePath\" alt=\"Alternate Text\" title=\"Title\" />";
