Really? How can it not already be! 😭 One goes to all the hard work to set out a responsive layout to find out that not all elements will work. I mean seriously...
Er.... So all I did was add the DataTable to the form and then set the x, y, width and height props to the 'parent' container's x, y, width and height values.... (e.g. Height = MainSectionContainer1_3.Height). Seems to work. I do wonder why this is isn't natively supported MSFT... 🤔
This is still not working. Adding a DataTable to a Container control (i.e. when the Container is the currently selected control) - either by the Insert menu or Copy/Paste does NOT work correctly. It results in the DataTable being inserted as a sibling of the Container. As an aside, Gallery controls work correctly.
