Multi Column Combo Box

Question

Hello,

 

I wanted to develop multi column combo in asp.net. I also need add search facility in it. How can I achieve this? If anyone has code then please send.

Is there any third party control available for multi column combo ?

Telrik having it , but I do not wanna purchase all control . I need to purchase only combo box.

If any other 3rd party controls are available , from which I can purchase only combo then please tell me.

-Thanks.
