Concurrency violation: the UpdateCommand affected 0 of the expected 1 records. Visual C# 2010

Question

i\'m sorry. i wouldn\'t post this if i weren\'t out of ideas. i\'ve tried everything in the forums, but to no avail.

so i have 2 tables. both are empty at the beginn

Answer 1

i have the same problem. but i am using Visual studio 2010 with C# and windows form. i solved my problem by placing "this.contactDBDataSet.AcceptChanges(); before "this.tableAdapterManager.UpdateAll(this.contactDBDataSet);". here is the sample.

private void peopleBindingNavigatorSaveItem_Click_2(object sender, EventArgs e)
{
    this.Validate();
    this.peopleBindingSource.EndEdit();
    this.contactDBDataSet.AcceptChanges();// added by Humayoo
    this.tableAdapterManager.UpdateAll(this.contactDBDataSet);


}
