placeholders

@ Abhay and Laks... Thank you ...:)
I had coded in C# a placeholder like this.. 
...but I cannot do anything with it...I also tried adding a hyperlink and when I give it a text value it comes up as an "error  creating control"...
Not sure what to do now...Please help...

Place holder syntax

    EnableTheming="True|False"
    EnableViewState="True|False"
    ID="string"
    OnDataBinding="DataBinding event handler"
    OnDisposed="Disposed event handler"
    OnInit="Init event handler"
    OnLoad="Load event handler"
    OnPreRender="PreRender event handler"
    OnUnload="Unload event handler"
    runat="server"
    SkinID="string"
    Visible="True|False"
/>

Try as below

PlaceHolder plh = new PlaceHolder();
 plh.Controls.Add(new LiteralControl("txtEmpName"));
 placeHolder.Controls.Add(holder);
