Hi
In UniDbGrid ,columns don't get CustomConstraint.
I Create UniDbGrid in Runtime and set fields,But UniDbGrid columns don't have CustomConstraint that Field in dataset has.
I write below code
For i := Columns.Count - 1 DownTo 0 do
Columns[i].Field.CustomConstraint:=ASource.DataSet.Fields[i].CustomConstraint;
But Show below Error
First chance exception at $0040BF8A. Exception class $C0000005 with message 'access violation at 0x0040bf8a: write of address 0x00000094'. Process P.exe (5616)
Best Regards.
