Thanks for writing and for the attached screenshots.
This behavior seems to be related to the native ScrollViewer
component which we are internally using in RadDataBoundListBox
. It appears that the ScrollViewer
does not apply an initial scroll offset to reflect the size change of the element which has been expanded.
We will perform some additional investigations and if we encounter something that we could do on our side to address this - we will include it in an Internal Build for you.
Let us know should you have additional questions.
