Question

一直试图解决这个问题大约一个小时！

我创建了一个有一个主要表单的应用程序，它在Program.cs中启动，就像这样

frmFleetMain frmW = new frmFleetMain();
frmW.iNIPathAndFile = GlobalInfo.iNIPathAndFile;
frmW.SetUser(GlobalInfo.Username);
Application.Run(frmW);

和在主窗体中启动的1个子窗体，如下所示

                if (recordid != "")
                {
                    frmFleetSave frmsave = new frmFleetSave();
                    frmsave.Rowid = int.Parse(recordid);
                    frmsave.ShowDialog();                        

                   dgvMain.Rows[rowindx].Cells[0].Style.BackColor = Color.Red;                       

               oFuel.Filter = FLEET_FUEL.ColumnNames.FUEL_SEQUENCE + " = "+recordid;
                    oFuel.FLEET_NO = int.Parse(GlobalInfo.FLEETNO);
                    oFuel.Filter = "";
                    GlobalInfo.FLEETNO = "";
                }

在frmsave的btnclose事件中，我有这段代码

if (GlobalInfo.FLEETNO == "")
{
   DialogResult result = MessageBox.Show("Record will not be updated!Click OK to try again or CANCEL to close.", "Warning", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation);
   if (result == DialogResult.Cancel)
   {                    
      this.Close();//this closes both forms -this is not what i want
   }
}
else
{
   this.Close();//this closes frmsave only-this is what i want:)
}

我无法弄清楚为什么会发生这种情况！帮助：）

求助：

 if (recordid != "")
                {
                    frmFleetSave frmsave = new frmFleetSave();
                    frmsave.Rowid = int.Parse(recordid);
                    frmsave.ShowDialog();

                    if (frmsave.ssave)//get a bool variable indicating we can save! :-P
                    {

                        oFuel.Filter = FLEET_FUEL.ColumnNames.FUEL_SEQUENCE + " = " + recordid;
                        oFuel.FLEET_NO = int.Parse(GlobalInfo.FLEETNO);
                        oFuel.Filter = "";
                        GlobalInfo.FLEETNO = "";
                    }

}

Answer 1

尝试将frmsave.ShowDialog();更改为frmsave.ShowDialog(this);

并将其他代码更改为：

        DialogResult result = MessageBox.Show(this, "Record will not be updated!Click OK to try again or CANCEL to close.", "Warning", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation);
        if (result == DialogResult.Cancel)
        {
            Close();
        }

这在我的电脑上工作正常......

}

This.close（）关闭主窗体以及
