密钥启动文本框不起作用 [英] Key up event of a textbox is not working

问题描述

嗨dere，



i我在winapp工作。有2个文本框，1个下拉列表，1个日期时间选择器。我必须通过按下从1个控件移动到另一个控件输入。我的第一个控件是Paymode（下拉），第二个是PayDate（datetimepicker），第三个是PayAmount（文本框），第四个是Cred / CheqNo（文本框）。



因此，当我选择paymode中的现金时，它在第一时间完美地移动，当我在paymode中选择信用时，它会在第二次移动到下一个控制。有时它在日期控制附近，有时接近payamount。



它以前工作得很好，但现在还没有工作。已经检查了表格的关键预览属性..这将是我不明白的问题。请帮我解决这个..



i我发给你的代码，

hi dere,

i am working in winapp.Have taken 2 textbox with 1 dropdown n 1 datetime picker.I have to move from 1 control to another by pressing enter.My first control is Paymode(dropdown),2nd one is PayDate(datetimepicker),then 3rd one is PayAmount(Textbox) and fourth one is Cred/CheqNo(Textbox).

private void txtPayAmnt_KeyUp(object sender, KeyEventArgs e)
       {
           if (e.KeyCode == Keys.Enter)
           {
               if (cmbPayMode.SelectedIndex == 0)
               {
                   MessageBox.Show("Please  Select  the  PayMode..", "Restaurant", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                   cmbPayMode.Focus();
                   if (cmbPayMode.Focus())
                   {
                       cmbPayMode.FlatStyle = FlatStyle.Popup;
                       cmbPayMode.BackColor = System.Drawing.Color.Brown;
                       cmbPayMode.ForeColor = System.Drawing.Color.White;
                   }
               }
               else if (cmbPayMode.SelectedIndex != 1)
               {
                  txtCredChq.Focus();
               }
               else
               {
                   int j = dgvPayDetails.CurrentRow.Index;
                   dgvPayDetails.Rows[j].Cells[0].Value = cmbPayMode.Text;
                   dgvPayDetails.Rows[j].Cells[1].Value = txtPayAmnt.Text;
                   dgvPayDetails.Rows[j].Cells[2].Value = txtCredChq.Text;
                   dgvPayDetails.Rows[j].Cells[3].Value = dtpPayDt.Text;
                   dgvPayDetails.Rows.Add();
                   dgvPayDetails.CurrentCell = dgvPayDetails.Rows[j + 1].Cells[0];
                   cmbPayMode.SelectedIndex = 0;
                   txtPayAmnt.Text = "";
                   txtCredChq.Text = "";
               }
           }
       }

谢谢..

Thanks..

推荐答案

这似乎是一个算法问题：



如果触发 cmbPayMode.SelectedIndex == 0 然后触发 cmbPayMode.SelectedIndex！= 1



唯一将触发 else 的情况是 cmbPayMode.SelectedIndex == 1

It's seems to be a problem of algorithm :

If cmbPayMode.SelectedIndex==0 is triggered then cmbPayMode.SelectedIndex != 1 is triggered too

The only case that the else will be triggered is if cmbPayMode.SelectedIndex == 1
