Question

我有两个表（kala，接收）和两个winforms（kala，接收），我想当我填写接收表格（specialy txtqty）并插入数据时，它（txtqty）添加到kala表字段（txtkqty）。如何在接收表格中的按钮后面写这个代码。接待表格：

private void btninsert_Click(object sender, EventArgs e)
        {
            string check = br.createreceipt(int.Parse(txtreceptcode.Text),
                                            int.Parse(comboBox_kala.SelectedValue.ToString()),
                                            int.Parse(comboBox_suplier.SelectedValue.ToString()
                                                ), int.Parse(txtqty.Text), DateTime.Parse(dateTimePicker_recept.Text));
            if (check == "true")
            {
                dtrecept = br.getdata();
                dataGridViewrecept.DataSource = dtrecept;
                txtreceptcode.Text = null;
                txtqty.Text = null;
            }


        }

kala表格

 private void btnkalainsert_Click(object sender, EventArgs e)
        {
            string check = bk.createkala(int.Parse(txtkalacode.Text), txtkalaname.Text, int.Parse(txtkqty.Text),
                                         int.Parse(txtkalapoint.Text));
            if (check=="true")
            {
                dt = bk.Getdata();
                dataGridViewkala.DataSource = dt;
            }
            else
            {
                MessageBox.Show(check);
            }

Answer 1

您可以使用此解决方案：

Form frm = Application.OpenForms["formName"];  
TextBox txt = (TextBox)frm.Controls.Find("textboxName",true)[0];  
txt.Text = "yourValue";

请注意，此代码不安全，请自行执行安全部件（尝试捕获可能是很好的方法，您也可以通过检查if / else块中容易出错的部分来实现）
