I have a c1flexgrid form component one that gets data from a datatable. The user Is allowed to change the order of the columns.
My Question is, is it possible to safe the schema of the flexgrid, so that the user can load it the next time he open the Programm.
Yes, you can save the flexgrid [WinForms] information. Try using the SaveGrid/LoadGrid methods to save/load the grid information.
FlexGrid exposes many forms of saving/loading the data/information. To learn more about them the following documentation section should help: https://www.grapecity.com/componentone/docs/win/online-flexgrid/savingloadingandprinting.html
P.S.: GrapeCity has platform specific public forums as well to discuss such requirements. See: https://www.grapecity.com/forums
