datetime picker cntrol [英] datetime picker cntrol

问题描述

我使用以下代码在datetime选择器中设置null值。

dtInsuranceDate.Text = row [" DateInsured"]。ToString（）;我正在从数据库行中分配值

如果  dtInsuranceDate.Text = '01 -01-1900 '和 当我点击日期时间选择器以使用正确的日期更新值时， 我怎么能带来 当前日期 作为日历弹出窗口的默认值而不是
到01-01-1900。任何帮助将不胜感激

 
 dtInsuranceDate.Text = row [" DateInsured"]。ToString（）; 
 
 
 if（dtInsuranceDate.Value.ToShortDateString（）==" 01/01/1900"）
 {
 dtInsuranceDate.Format = DateTimePickerFormat.Custom; 
 dtInsuranceDate.CustomFormat ="英寸; 
 checkBox3.Checked = true; 
 
} 
 

感谢

嗨Pol，

>>如何在日历弹出窗口中将当前日期作为默认日期而不是01-01-1900。

您可以在if语句中设置当前日期：

 dtInsuranceDate.Text = row [" DateInsured"]。的ToString（）; 
 if（dtInsuranceDate.Value.ToShortDateString（）==" 01/01/1900"）
 {
 //dtInsuranceDate.Format = DateTimePickerFormat.Custom; 
 //dtInsuranceDate.CustomFormat ="英寸; 
 dtInsuranceDate.Format = DateTimePickerFormat.Long; 
 dtInsuranceDate.Value = DateTime.Now; 
 checkBox3.Checked = true; 
}

I am using the following code to set the null value in datetime picker.

dtInsuranceDate.Text = row["DateInsured"].ToString(); I am assigning the value from database row

If dtInsuranceDate.Text ='01-01-1900' and and   when I click the datetime picker to update the value with correct date ,  how can I bring the  current date  as default in the calendar popup rather than going to 01-01-1900. Any help would be appreciated

dtInsuranceDate.Text = row["DateInsured"].ToString();
                    if (dtInsuranceDate.Value.ToShortDateString() == "01/01/1900")
                    {
                        dtInsuranceDate.Format = DateTimePickerFormat.Custom;
                        dtInsuranceDate.CustomFormat = " ";
                        checkBox3.Checked = true;

                    }

With thanks

Hi Pol,

>>how can I bring the current date as default in the calendar popup rather than going to 01-01-1900.

You can set the current date in the if statement:

    dtInsuranceDate.Text = row["DateInsured"].ToString();
    if (dtInsuranceDate.Value.ToShortDateString() == "01/01/1900")
    {
        //dtInsuranceDate.Format = DateTimePickerFormat.Custom;
        //dtInsuranceDate.CustomFormat = " ";
        dtInsuranceDate.Format = DateTimePickerFormat.Long;
        dtInsuranceDate.Value = DateTime.Now;
        checkBox3.Checked = true;
    }
