Saving using binding navigator

C#

Am I missing something here? I thought when you take and hit the save button on the premade bindingnavigator it will update all your records.

Here is what is strange. when i run the program in the developer and make a change and hit save it appears to save it. I close the program and load it again in the developer and the data is there. However; when I look in my database that the data is suppose to be written to, the data update does not exist. Am I suppose to add something to the click event other than the default of:

private void bookListBindingNavigatorSaveItem_Click(object sender, EventArgs e)
        {
            this.Validate();
            this.bookListBindingSource.EndEdit();
            this.tableAdapterManager.UpdateAll(this.bookdbDataSet);

        }
