Hi,
when using an AdvComboBox with a Label in a Gridpanel, the label is displayed not where it should be (TopLeft) and the height of the control seems to be different like LabeledEdit.
This is how the TGridPanel incorrectly treats controls where a secondary child control is generated. We found no way to change this TGridPanel behavior. We see the same wrong behavior in fact with the standard VCL TLabeledEdit. We suggest to put a control like TAdvComboBox on a container control ( like a TPanel) in the TGridPanel.
