How to bind Generic Dictionary with dropdown list

I was searching for binding the dictionary with dropdown list, the solution I found was consist of binding the Key as ‘DataValueField’ and value as ‘DataTextField’ of dictionary object.

But my problem was to bind the object (value collection of the dictionary)as datasource and its property to the dropdown ‘DataValueField’ and ‘DataTextField’.

The beauty of Generic dictionary object is that it can return you the value collection by using ‘Values’ property of the dictionary.

So here is the example.

<asp:DropDownList

ID="ddlCustomer"

runat="server"

DataSource='<%#Customers.Values%>'

DataTextField="Name"

DataValueField="ID">

</asp:DropDownList>

Couple of days back, I was using ASP.Net Menu Control. I saw the way it generates html its difficult to apply styles (css). I got stuck with the same problem. but thanks to control adapter it made my life easy.

The control adapters are the coolest thing, it let you change the HTML markup produced by ASP.NET controls. So, why invent a new control to generate the markup the way you want.

For the detail information about the control adapters and the downloads just refer: http://www.asp.net/CSSAdapters/Default.aspx
