Database problem in C#

[pr0g4fun]

I am building an application for a football club with a database and I have this problem:

 private void finansijeBindingNavigatorSaveItem_Click(object sender, EventArgs e)
        {
            this.Validate();
            this.finansijeBindingSource.EndEdit();
            this.tableAdapterManager.UpdateAll(this.fudbalski_klubDataSet1);
        }

When I run this, and either add, delete or edit the data, then save and close the form and go back into the application, the data was not saved.

Does anyone know how to fix this?

Thanks!

Could you post the SQL part?
