You have a terrible problem getting the ‘width’ property of a column under control. This is a problem because it is a basic functionality of the DataGrid. Again, there is something wrong in version 6.3.1.2....
See the picture. If the properties ‘width’ of the columns are set so that they do not fill the whole area, then.... empty space is filled with the last column.
It looks funny, but this is probably already the 4th version of the component , which works badly.
Why don't you do a trivial test like add 3 columns to adapter, add 3 columns to grid before publishing? Then set the width property so that the columns don't fill the whole working area, and then check the different DPI.
