掩码文本框不保存月份的前导0 [英] Mask textbox not saving leading 0 of the month

问题描述

当我输入数据02/22/2019时，我有一个文本框掩码并保存到数据网格，网格显示正确的格式，但掩码文本框显示22/22/019。它正在删除前导数据0.数据源是Access数据库，它设置为日期时间。有什么问题？我也在代码中尝试了它但仍然得到了相同的结果。



结果保存在网格和数据库中= 02/22/2019

当我选择网格行时，它在掩码文本框中显示为22/22/019，错过了0.



任何帮助



我尝试了什么：

I have a Textbox mask when I enter the data 02/22/2019 and save to the datagrid the grid shows the correct format but the mask textbox shows 22/22/019. It's deleting the leading 0. Data source is Access database and it is set to date time. What is the issue? I have also tried it in code but still get the same results.

Results saved in Grid and database = 02/22/2019
When I select the grid row it shows in the mask textbox as 22/22/019, missing the 0.

Any help

What I have tried:

private void Form1_Load_1(object sender, EventArgs e)
        {      
 maskedTextBox1.Mask = "00/00/0000";

            maskedTextBox1.MaskInputRejected += new MaskInputRejectedEventHandler(maskedTextBox1_MaskInputRejected);
            maskedTextBox1.KeyDown += new KeyEventHandler(maskedTextBox1_KeyDown);
        }

        void maskedTextBox1_MaskInputRejected(object sender, MaskInputRejectedEventArgs e)
        {
            if (maskedTextBox1.MaskFull)
            {
                toolTip1.ToolTipTitle = "Input Rejected - Too Much Data";
                toolTip1.Show("You cannot enter any more data into the date field. Delete some characters in order to insert more data.", maskedTextBox1, 0, -20, 5000);
            }
            else if (e.Position == maskedTextBox1.Mask.Length)
            {
                toolTip1.ToolTipTitle = "Input Rejected - End of Field";
                toolTip1.Show("You cannot add extra characters to the end of this date field.", maskedTextBox1, 0, -20, 5000);
            }
            else
            {
                toolTip1.ToolTipTitle = "Input Rejected";
                toolTip1.Show("You can only add numeric characters (0-9) into this date field.", maskedTextBox1, 0, -20, 5000);
            }
        }

推荐答案

我找到了答案。



转到蒙版文本框的属性。选择DataBindings，然后选择Advanced。在对话框中间的格式类型列表框中选择自定义。在右侧的自定义格式框中输入MM / dd / yyyy。



我希望这有助于其他人

I have found the answer.

Go to Property of the masked text box. Select 'DataBindings', then 'Advanced'. Select 'Custom' in the 'Format Type' list box in the middle of the dialog box. Enter 'MM/dd/yyyy' in the 'Custom Format' box to the right.

I hope this helps others
