Hello,
We have just added the RadComboBox to a page in our site for Country selection, to replace the existing lookup based on the Ajax Control Toolkit Auto Complete Extender (as clients has commented that this was too slow).
The ComboBox is loaded during Page_Load with a list Countries from the database (237 rows), in the same way that you would load a normal ASP.NET DropDownList. The definition for the ComboBox in the page markup us as follows:
It works absolutely fine running under IE7 and IE8, the response is pretty much instant. However it is painfully slow under IE6. It takes 1 or 2 seconds after entering any characters for the list to be displayed and the matching item selected. This is a problem for us as most of our clients (unfortunately) are running IE6!
Is this a known problem? Any advice on how we can improve the perfomance?
Thanks in advance.

Hi Marcus,
This is strange as I modified this demo (locally on my side) by binding the RadComboBox three times to the SqlDataSource on the page (which resulted in 3 x 91 Items to load in RCB) and tried the MarkFirstMatch functionality in IE6 - it worked as fast as in IE7.
Is there something that I am missing?
