数据Beteen表单C# [英] Data Beteen forms c#

问题描述

你好，

我正在编写一个小的调度程序应用程序.在这种情况下，我需要将3个字段的数据从子级移回父级表单.代码如下.

Hello,

I am writing a small scheduler application. In this i need to move 3 fields of data from child back to parent form. code is as follows.

private void calendar1_DoubleClick(object sender, EventArgs e)
        {
         AppointmentDialog _appDialog = new AppointmentDialog(MembersDT);
            
            if (_appDialog.ShowDialog() == DialogResult.OK)
            {
   DataRowView drv = (DataRowView)mycombo.SelectedItem;
                textBox1.Text = drv.Row.ItemArray[0].ToString();
                textBox2.Text = drv.Row.ItemArray[1].ToString();
                textBox3.Text = drv.Row.ItemArray[2].ToString();
            }
        }

现在我在textbox1，textbox2，textbox3中有三个字段.我需要它们以父级形式进行更新.请提出建议.

推荐答案

正确的方法:

将这3个值声明为AppointmentDialog类的公共成员.
当DialogResult.OK时，则从AppointmentDialog类复制.

Declare those 3 values as public members of the AppointmentDialog class.
When DialogResult.OK then copy from the AppointmentDialog class.

public static string FirstValue ="";
public static string SecondValue ="";
public static string ThirdValue ="";

private void calendar1_DoubleClick(object sender, EventArgs e)
{
   AppointmentDialog _appDialog = new AppointmentDialog(MembersDT);

   if (_appDialog.ShowDialog() == DialogResult.OK)
   {
      DataRowView drv = (DataRowView)mycombo.SelectedItem;
      textBox1.Text = drv.Row.ItemArray[0].ToString();
      textBox2.Text = drv.Row.ItemArray[1].ToString();
      textBox3.Text = drv.Row.ItemArray[2].ToString();
      FirstValue    = drv.Row.ItemArray[0].ToString();
      SecondValue   = drv.Row.ItemArray[1].ToString();
      ThirdValue    = drv.Row.ItemArray[2].ToString();
   }
}

现在您可以使用子表单名称从父表单获取
示例:

now you can get from parent form using child form name
Example:

Child.FirstValue;
