What I have tried:

frm_employees emp_form = new frm_employees();
            emp_form.txt_empid.Text = txt_emp_code.Text;
            emp_form.Show();

推荐答案

参考这个例子



子表单

refer this example

Child Form

public partial class FormChildEmployee : Form
    {
        public frm_employees ParentFormObject { get; set; }  // create a property for parent form

        public FormChildEmployee()
        {
            InitializeComponent();
        }
         
        private void btnSelect_Click(object sender, EventArgs e)
        {
            ParentFormObject.txt_empid.Text = txt_emp_code.Text; // assign the child's textbox value to the parent form Textbox without creating new instance
        }
    }

在父表格中

in Parent Form

// opening the child pop up on button click in parent form
private void btnOpenPopUpChild_Click(object sender, EventArgs e)
       {
           FormChildEmployee objChild = new FormChildEmployee();
           objChild.ParentFormObject = this; // initialise this object( parent form ) to the property created.
           objChild.Show();
       }

注意：将父表单文本框（ txt_empid ）设为设计视图中的公共修饰符。

您正在尝试使用子形式将数据传回给它的父？

这很简单 - 所有你需要的是一个事件（也许是一个属性）。

见这里：在两种形式之间传递信息，第2部分：儿童到父母 [ ^ ]

Your are trying to have a "child" form which passes data back to it's "parent"?
That's pretty simple - all you need is an event (and maybe a property).
