private void tblPointsBindingNavigatorSaveItem_Click(object sender, EventArgs e)
{
this.Validate();
this.tblPointsBindingSource.EndEdit();
this.tableAdapterManager.UpdateAll(this._9thXIPointsDataSet1);
int test = 0;
test += Convert.ToInt32(pointsTextBox.Text);
label1.Text = test.ToString();
}
现在是我的代码,但它只显示 1 行的值,但我希望它显示每一行并为添加的每个新行加起来
