Hi,

I am creating a form in .net windows application. Just watch the below codes.These codes for update process.

 private void imgbtnUpdate1_Click(object sender, EventArgs e)
        {
            if ((txtPhoneNo.Text != "") && (dtpDateofRecharge.Text != "") && (cmbOperator.Text != "") && (txtAmount.Text != ""))
            {
                DialogResult dr = MessageBox.Show("Do you Want to Update?","Question",MessageBoxButtons.YesNo,MessageBoxIcon.Question);
                if (dr == DialogResult.Yes)
                {
                    con.Open();
                    SqlCommand cmd = new SqlCommand("update phonebill set PhoneNo='"+txtPhoneNo.Text+"',DateOfRecharge='"+dtpDateofRecharge.Value+"',
Operator='"+cmbOperator.Text+"',Amount='"+txtAmount.Text+"' where PhoneNo='"+txtPhoneNo.Text+"'",con);
                    cmd.ExecuteNonQuery();
                    con.Close();
                    MessageBox.Show("Updated Successfully","Information",MessageBoxButtons.OK,MessageBoxIcon.Information);                                      
                }
            }
        }

private void dgvPhone_CellEnter(object sender, DataGridViewCellEventArgs e)
       {
           txtPhoneNo.Text=dgvPhone.Rows[e.RowIndex].Cells["PhoneNo"].Value.ToString();
           dtpDateofRecharge.Text=dgvPhone.Rows[e.RowIndex].Cells["DateOfRecharge"].Value.ToString();
           cmbOperator.Text=dgvPhone.Rows[e.RowIndex].Cells["Operator"].Value.ToString();
           txtAmount.Text=dgvPhone.Rows[e.RowIndex].Cells["Amount"].Value.ToString();
       }

现在我的问题是，如果我在表格2中使用datagridview，如何通过使用单元格输入事件将这些数据放置在表格1中的相应文本框中.

请帮助我.

谢谢，

推荐答案

可能有两种方法可以完成此任务
>通过设置属性访问两个文本框
>将其公开

创建具有文本框的Next表单的对象.
Form2 f2 = new Form2();
现在在单元格输入事件中，您可以使用代码

there may be two methods to do this task
>access two text boxes by setting properties
>make them public

Create the object of Next form which have text boxes.
Form2 f2=new Form2();
now on cell enter event you can use the code

 f2.textbox1.text=dgvPhone.Rows[e.RowIndex].Cells["data1"].Value.ToString();
f2.textbox2.text=dgvPhone.Rows[e.RowIndex].Cells["data2"].Value.ToString();
f2.show();
