Dear Telerik,
we are using a Telerik RadCombobox to pull in a data-bound list of documents to choose from as follows. However, the list is getting really huge at the moment (>700) and we don't really want to go down the route of load-on-demand, because of performance.
The Combobox sits in a pop-up control as well and due to the height of the Combobox (with name and description), the list gets cut off after a few hundred elements in FireFox (latest) although the markup is fine.
I've tried to programatically set the height of the drop down using the cbDocument.Height = Unit.Pixel(cbDocument.Items.Count * 50) method, but it overflows.
This only seems to happen in firefox and not in IE7, Chrome, etc...
Typically when this happens, a black border appears around the corners. Please contact me if you need anymore information
