The Anchor and Dock property is not relevant to the RadPopupContainer and should not be taken into account while calculating the size of the popup drop-down.

Workaround:

Avoid setting the Anchor and Dock properties of the RadPopupContainer.

Hi Progress Team,

I have encountered another issue in the RadPopupEditor control. For RadSpinEditor controls as well as for RadTextBox controls on the Popup container form, no value changed or validating/validation events are fired. For RadSpinEditor controls the ValueChanged event is fired when the spin buttons are used to change the value but when the user directly enters a value in the editor element and the control losts the focus (either by TAB or mouse click outside the control) the ValueChanged event is missing.

I have attached a small VS2017 project which illustrates the issue.

Thank you very much!

Regards,

Jürgen
