Solution 1

check if your identity key has auto increment by 1 set to true or not in the database. if that is the case you can not manually change the identity value.

make auto increment by 1 to false from the table and try again. it should work.

this is right if you have set auto increment true than its not updating manually.

You can update the identity column manually by reseeding the identity column

SQL

-- Resets the current Identity value to maximum value
DBCC CHECKIDENT ('TestTable', RESEED, 11);

But don't forget to seed the column again after updating

SQL

-- Returns current Identity Value
DBCC CHECKIDENT ('TestTable', NORESEED);
