标题: TextBox焦点切后TouchLeave事件换引起的“请稍候”提示框问题。

TextBox的TouchLeave事件中更新赋值了Label的Text属性。
打包版的APP中会出现”请稍候“提示框，影响体验。开发版的APP不会出现。
附件中我上传了2个版本的操作视频。

TextBox的TouchLeave事件代码如下：
private void txtAmount_TouchLeave(object sender, EventArgs e)
      {
         string Amount = txtAmount.Text;
         if (Amount != oldAmount)
         {
            if (Amount == "" || Amount == "0" || Amount == "0.0")
            {
                  txtAmount.Text = oldAmount;
            }
            else
            {
                  handleUI();
            }
         }
      }

      private void handleUI()
      {
         string WholePackRate = txtWholePackRate.Text;
         string WholeAmount = txtWholeAmount.Text;
         string Amount = txtAmount.Text;
         if (string.IsNullOrEmpty(WholePackRate) || string.IsNullOrEmpty(Amount))
            return;

         double dWholePackRate = 0, dAmount = 0;
         bool bFlag = double.TryParse(WholePackRate, out dWholePackRate);
         if (!bFlag) return;
         bFlag = double.TryParse(Amount, out dAmount);
         if (!bFlag) return;
         string s = Math.Ceiling(dAmount / dWholePackRate).ToString();
         txtWholeAmount.Text = s;

         if (lblTaskState.Text == "未执行")
         {
            lblTaskState.ForeColor = System.Drawing.Color.Red;
         }
      }

这边测试使用你提供的handleUI()方法,并未发生loading,是否是你这边更新了更多的内容.
