I lost my mind reading capability recently so I need you to elaborate what are you trying to accomplish. your want a group of components to do what? -- "A scholar who cherishes the love of comfort is not fit to be deemed a scholar." -- Lao-Tzu (570?-490?

It's usually done with frames in a TScrollbox, for example. You add frames as needed at run-time. The main difference compared with a TDBCtrlGrid is Windows resource usage. A TDBCtrlGrid has only one set of "real" controls, on the currently active pane for the active record. All others are just images, so they do not use window handles. A scrollbox full of frames uses a lot more window handles since all frames are "live". Fortunately that is not a big problem on todays Windows installations, but if you need to be able to handle a *lot* of such frames at once (to display a large list of objects, for example) it would pay to turn the design into a fixed number of frames (just enough to fill the visible area of a host panel) that display different objects as the user scrolls through the list (basically like a TDBGrid handles its rows).
