Winforms在调用之后和值更改事件之后重置数字更新值为0

Question

我在WinForms中的数字更新控件上有一个值更改事件，我在需要时更改了值。它的价值改变如下：

  private void numericUpDown1_ValueChanged(object sender, EventArgs e)
        {
            if (InvokeRequired)
            {
                // after we've done all the processing, 
                this.Invoke(new MethodInvoker(delegate {
                    this.lblNumberOfTransactionsFetched.Text = "Fetched:  " + numericUpDown1.Value + " out of "  + this._sortedList.Count() + " transactions";
                }));
                return;
            }
        }

基本上我在async方法的形式上显示一个结果，该方法向PayPal发出网络请求，并且每次按下按钮时我都会尝试重置此值：

private async void materialRaisedButton3_Click(object sender, EventArgs e)
    {
   // Reset the numeric updown value to 0 again before it's displayed on the form again      
  }

我怎样才能做到这一点？

编辑：@Trey这是触发事件时我正在调用的实际代码：

  private async void materialRaisedButton3_Click(object sender, EventArgs e)
        {
            this.materialListView1.Items.Clear();
            Application.DoEvents();

            _detail = new List<TransactionDetails>();
             _sortedList = new List<Transactions>();
             var startDate = (dateFrom.Value.Year + "-" + dateFrom.Value.Date.Month + "-" + this.dateFrom.Value.Date.Day + "T00:00:00Z");
            var endDate = (dateTo.Value.Year + "-" + dateTo.Value.Date.Month + "-" + this.dateTo.Value.Date.Day + "T23:59:00Z");
            if (DateTime.Parse(startDate) > DateTime.Parse(endDate))
            {
                MessageBox.Show("Start date cannot be higher than end date!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
                return;
            }
            else if (DateTime.Parse(startDate) < DateTime.Parse(endDate))
            {


                lista = new List<TransactionSearchResponseType>();
                transactions = new List<Transactions>();
                loadingCircle1.Visible = true;
                loadingCircle1.Active = true;
                lblWait.Visible = true;
                this.materialRaisedButton3.Enabled = false;
                await DoTask(startDate, endDate);
                _sortedList = transactions.DistinctBy(x => x.TransactionID).OrderByDescending(x => x.TimeStamp).ToList();

                this.lblNumberOfTransactionsFetched.Visible = true;

                for (int i = 0; i < _sortedList.Count(); i++)
                {
                    await GetTransactionDetails(_sortedList[i].TransactionID, _sortedList[i].TimeZone);
                }

                foreach (var item in _sortedList)
                {
                    var itemInB = _detail.Where(x => x.TransactionID == item.TransactionID).FirstOrDefault();

                    if (itemInB != null)
                        item.transactionDetails.Add(itemInB);
                 }
                loadingCircle1.Active = false;
                loadingCircle1.Visible = false;
                lblWait.Visible = false;
                seedListView(_sortedList);

                listOfTransactionDetailsCSV = new List<TransactionDetails>();
                foreach (var item in _sortedList)
                {
                    listOfTransactionDetailsCSV.Add(item.transactionDetails[0]);
                }

                lblNumberOfTransactionsFetched.Visible = false;

                this.materialRaisedButton3.Enabled = true;
            }
        }
