Hi,

C#

 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);

                    MessageBox.Show("Updated Successfully","Information",MessageBoxButtons.OK,MessageBoxIcon.Information);                                      
                }
            }
        }

C#

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();

hi,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

C#

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

Hi, where(location) should i create a object for form 2?

on cell enter event method

Viswanthan.M. 6-Aug-11 14:17pm

private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
Form2 f2 = new Form2();
f2.txtName.Text = dataGridView1.Rows[e.RowIndex].Cells["Name"].Value.ToString();
f2.txtId.Text = dataGridView1.Rows[e.RowIndex].Cells["Id"].Value.ToString();
f2.Show();
}

If i do like this , it continuously open form 2.

use form taht have textboxes on that.
may be Form1 or form2 ,as you take it in your application.
if you want to show values on next form by clicking cells again and again
then create an object of Form(with twotext boxes) on previous form load event
and use
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
f2.close();
f2=new Form2();
f2.txtName.Text = dataGridView1.Rows[e.RowIndex].Cells["Name"].Value.ToString();
f2.txtId.Text = dataGridView1.Rows[e.RowIndex].Cells["Id"].Value.ToString();
f2.Show();
}

I am using text boxes in form 1.In button click event in form 1, i use this code,
private void button4_Click(object sender, EventArgs e)
{
if ((txtName.Text != "") && (txtId.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 report set name='" + txtName.Text + "' where id='" + txtId.Text + "'", con);
cmd.ExecuteNonQuery();
con.Close();
MessageBox.Show("Updated Successfully", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);

}
}

}

In form 2,in cell enter event of datagridview, i use this code,

Form1 f2 = new Form1();
f2.txtName.Text = dataGridView1.Rows[e.RowIndex].Cells["Name"].Value.ToString();
f2.txtId.Text = dataGridView1.Rows[e.RowIndex].Cells["Id"].Value.ToString();
}

If use like this i will get form1 again and again,If i click any row in database of datagridview, i will get form 1 again and again.

Kindly help me
