Hi all,
My software have many layout files (*.lyt, *.xml) of UltraWingrid to customize UI (about 300 files). When I upgrade Infragistics from version 8.1 to 8.3, method Grid.DisplayLayout.Load throw excepion.
I have open layout file (*.lyt, *.xml) and see that: Layout file contain version: "...Infragistics.Win.UltraWinGrid.UltraGrid, Infragistics2.Win.UltraWinGrid.v8.1, Version=8.1.20081.1000..."
What must I do to convert Layout file (*.lyt) to lastest version 8.3 or avoid this error?
Thanks in advance!
What is the exception you are getting?
A layout file should be backward compatible with prior versions of the grid, you should not have to do anything to make it work.
Hi Mike,
Thanks for your answer. Don't you see: "Exception: Object reference not set... " in subject?
I view inner exception, that is NullReferenceException from LoadLayoutHelper.
In fact, layout file doesn't backwar compatible. I have try use UltraGrid 7.3 load layout UltraGrid, this exception still exist.
In history, version Infragistics 6.x doesn't have this error
If you try with your Project, You can see. Orelse, I will give you my project with my layout files.
Thanks
