I have this form in C#

I add an row, and update tableadapter. And then the primary key is 14098 in datagridview while the same row has 14117 on the server.

When i update again i get an dbconcurrency exception.

The primary key is int and autoincremeant is true, and seed/increment is set to 1 on both server and visual studio properties.

Please help

Solution 1

When you use identity column to autoincrement value on inserting data, it will always be incremented whether the data you wanted to insert was successfully inserted or not. As a result, the identity column will have some empty values. This page discusses the following problem. Link[^]

Solution 2

Ok, I have made a workaround by setting tableadapter fill right after tableadapter.update

Then the right primary key is used. But i think this is no good solution.
