    Hi I have several Rad Combo boxes that could potentially have tens of thousands of results in them and the performance of the combo boxes seems degrade after about 6000.

    now i accept the argument that is far to many result to have in a combo anyway so my idea to fixes this was to pre-populate the combo with say 100 results and then allow the user to type in to the combo and get the combo to repopulate with the top 100 result for the search they are doing.  

    problem is I needed to access the FilterText property to do this and it defined as a friend and will not let me access it. 

    anyone know of a way round this?

    Hi Mark,

    You could use combo's Load On Demand functionality. It loads data on small portions, offers filtering and you could get filtered text property on both client and the server. Please take a look at the Performance with WebServices online demo and the Load On Demand online documentation.
