I have a RadComboBox within the ItemTemplate of a DetailsView. When using EnableAutomaticLoadOnDemand, all records are initially loaded into the ComboBox. The same ComboBox initially loads no records if I move it outside the DetailsView. Is this a bug with DetailsView? Any known workarounds? I'd rather not use EnableLoadOnDemand and have to code each ComboBox. Code for the offending page is below. There is no code behind for this page.

On edit: looks like updating to the latest version fixed it.

Hi Derek,

I tried to reproduce the issue using the code provided, but unfortunately without success.
Could you please find the test page attached and give it a try?
Maybe there is something different in your implementation that causes the issue?

All the best,
