Hii,
Previously i had table and i set a default constrint to one of my column .
so , if not provided in linq class , then null was setting by default even though i set my default value to 4 in sql table,
Then i chnaged the property of that column from dbml , Set autogenrate to true .. and it was working..
now the problem is .. from other method when i try to give some other value for that column ...
it is throwing an error ..
A member that is computed or generated by the database cannot be changed.
i want to use default value when not prvided and my value when procvided it should get updated
