我希望我的网格视图复选框始终选中在asp.net中选中复选框true

Question

我有一个表t1和表t2。我的gridview填充了t1的值。如果选中复选框，则在每行的t1复选框t1将整行插入t2表并保存数据。 我希望我插入的行数据保存在t2中并与t1一起使用，然后检查比较行的复选框。 任何hwlp将不胜感激：

    for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
    {
        GridViewRow row = GridView1.Rows[i];
        CheckBox Chbox = (CheckBox)row.FindControl("chb1");

        if (Chbox.Checked == true)
        { 
            select++;
        }
    }
    if (select == 0)
    {

    }

    for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
    {

        string id = GridView1.Rows[i].Cells[1].Text;
        string name = GridView1.Rows[i].Cells[2].Text;
        string City = GridView1.Rows[i].Cells[3].Text;
        string Age = GridView1.Rows[i].Cells[4].Text;
        GridViewRow row = GridView1.Rows[i];
        CheckBox Chbox = (CheckBox)row.FindControl("chb1");


        if (Chbox.Checked == true)
        {
            con.Open();
            com = new SqlCommand("insert into info2 values('" + id + "','" + name + "','" + City + "','" + Age + "')", con);
            com.ExecuteNonQuery();
            con.Close();
            foreach (GridViewRow grow in GridView1.Rows)
            {

                int id1 = Convert.ToInt32(GridView1.DataKeys[row.RowIndex].Value);

                con.Open();
                com = new SqlCommand("Select * FROM info where id='" + id1 + "'", con);
                SqlDataReader dr = com.ExecuteReader();
                CheckBox ChkBoxRows = (CheckBox)row.FindControl("chbl1");
                if (dr.Read())
                {

                    Response.Write(GridView1.Rows[i].Cells[2].ToString());

                }


                //if (dr = 1)
                //{
                //    Chbox.Checked = true;

                //}
                //else
                //{
                //    Chbox.Checked = true;
                //}


                //com.ExecuteNonQuery();
                con.Close();
