问题描述

iam从两个文本框中添加列表框中的文本。如下所示

textbox2文本是某种文字

推荐答案

this is form1
private void listBox1_MouseDown(object sender, MouseEventArgs e)
        {
            try
            {
                listBox1.DoDragDrop(listBox1.Items[listBox1.SelectedIndex].ToString(), DragDropEffects.Move);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        private void txtBox1_DragEnter(object sender, DragEventArgs e)
        {
            try
            {
                if (e.Data.GetDataPresent(DataFormats.Text))
                {
                    e.Effect = DragDropEffects.Move;
                }
                else
                {
                    e.Effect = DragDropEffects.None;
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        private void txtBox1_DragDrop(object sender, DragEventArgs e)
        {
            txtwpAM1.Text = System.Convert.ToString(e.Data.GetData(DataFormats.Text).ToString());
        }

这是我的form2代码，用于添加项目，例如

textbox1是123和textbox2是某种文字

this is my form2 code for add items like
textbox1 is 123 and textbox2 is sometext

private void button1_Click(object sender, EventArgs e)
        {
            _form.AddListBoxItem(textBox2.Text + "D"+ " "+textBox1.Text);

            this.Close();
        }

当我从列表框项目中拖动它应该被触发123是textbox2而sometext是textbox1

when i drag from listbox item it should be fired 123 is textbox2 and sometext is textbox1
