ASP.NET DropDownList Extension

Question

I am trying to create my own control that inherits from DropDownList.

I need to add a new property to the ListItem (in the item collection).

<cc1:MyDropDownList ID="MyDropDownList1" runat="server">   
   <asp:ListItem myProperty="true" text="sometext" ... />                     

</cc1: MyDropDownList>    

How can i do this?

Answer 1

Even if you inherit DropDownList, you cannot add this property because you have to add it to the ListItem control.
But the problem is that the ListItem class is sealed, so you cannot inherit it.

Answer 2

Can you extend the capabilities of the client side with jQuery?
