在不使用按钮的情况下单击网格视图行时，不会显示模式弹出窗口

当点击网格视图行时，我需要显示一个模式弹出窗口（没有任何按钮），我通过点击网格视图来显示弹出窗口，但不知道将值绑定到模式弹出窗口中显示的文本框。。所以我需要的帮助

1. 将网格视图行（单击时）值绑定到模式弹出文本框
2. 只有当点击编辑按钮（位于模式弹出窗口底部）时，模式弹出文本框才可编辑
3. 编辑工作完成后，单击保存按钮（位于编辑按钮旁边的底部）时应保存编辑后的数据

protected void grid_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            GridViewRow row = e.Row;
            if (row.DataItem == null)
            {
                return;
            }
            try
            {
                switch (e.Row.RowType)
                {
                    case DataControlRowType.Header:
                        break;
                    case DataControlRowType.DataRow:
                        e.Row.Attributes.Add("onmouseover", "this.style.cursor='hand'");
                        e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(grid, "Select$" + e.Row.RowIndex.ToString()));
                        e.Row.Attributes.Add("onclick", String.Format("javascript:$find('{0}').show();", ModalPopupExtender2.ClientID));

                        TextBox1.Text = grid.SelectedRow.Cells[0].Text;
                        TextBox2.Text = grid.SelectedRow.Cells[1].Text;
                        TextBox3.Text = grid.SelectedRow.Cells[2].Text;
                        TextBox4.Text = grid.SelectedRow.Cells[3].Text;
                        TextBox5.Text = grid.SelectedRow.Cells[4].Text;
                        ModalPopupExtender2.Show();
                        break;
                }
            }
            catch
            {
                return;
            }
        }

由于我是asp.net的新手，请试着帮我提一些建议。

textBoxid.DataBindings.Add(new Binding("Text", customersBindingSource, "ID"));
textBoxname.DataBindings.Add(new Binding("Text", customersBindingSource, "NAME"));
textBoxcity.DataBindings.Add(new Binding("Text", customersBindingSource, "City"));

private void EditButton_Click(object sender, EventArgs e)
        {
            if (textBoxid.ReadOnly == true)
            {
                textBoxid.ReadOnly = false;
                //how many text boxes you have, do the same here
            }
            else
            {
                textBoxid.ReadOnly = true;
                //how many text boxes you have, do the same here
            }
        }
