Hi, in VCL DbGrid there is the possibility for a column to pick up a customized editor (a dialog), by setting the column ButtonStyle to cbsEllipsis and managing the OnEditButtonClick event.
UniGUI already implements various DbGrid editors (UniEdit, UniCombo, UniDBLoockUpComboBox, NumEdit, etc.).
In some cases, especially when there are many values to choose from, I think that the ellipsis button that could open a specialized dialog is the best solution. (and maybe it is not too difficult to implement...)
Thanks
Andrea
