Can you debug the code? I still don't understand after removing the ColumnCount property you still facing the same issue.

I got my result sir

foreach (DataGridViewRow row in dataGridView2.Rows)
{

foreach (DataGridViewCell cell in row.Cells)
{
value1 = row.Cells[0].Value.ToString();
value2 = row.Cells[1].Value.ToString();
value3 = row.Cells[2].Value.ToString();
value4 = row.Cells[3].Value.ToString();
value5 = row.Cells[4].Value.ToString();
cmd = new SqlCommand("insert into rule2 values ('" + value1.ToString() + "','" + value2.ToString() + "','" + value3.ToString() + "','" + value4.ToString() + "','" + value5.ToString() + "')", cn.con);
cmd.ExecuteNonQuery();
cmd.Dispose();
//MessageBox.Show("Execute Process!!");
}

MessageBox.Show("Process Complited");

Try the below coding(edit this as per your project)

protected void Button1_Click1(object sender, EventArgs e)
   {
       string a = Request.QueryString["var"];
       // TextBox1.Text = "";
       foreach (GridViewRow gvr in GridView1.Rows)
       {
           if (gvr.RowType == DataControlRowType.DataRow)
           {
               CheckBox cb = (CheckBox)(gvr.FindControl("CheckBox1"));
               if (cb.Checked == true)
               {   SqlConnection cn = new SqlConnection("Data Source=FABSYSXX-PC; Initial Catalog=rule; User Id=sa; Pwd=saadmin");
           cn.Open();
           SqlCommand cmd = new SqlCommand("Insert into Trans values('" + Session["count"].ToString() + "','" + gvr.Cells[1].Text + "','" + gvr.Cells[2].Text + "','" + gvr.Cells[3].Text + "','" + a + "')", cn); //Write Your Query to insert into database table

                   int iCount = cmd.ExecuteNonQuery();

                   cn.Close();
                   //TextBox1.Text = TextBox1.Text + "," + gvr.Cells[1].Text;
                  // TextBox2.Text = TextBox2.Text + "," + gvr.Cells[2].Text;
               }

           }

       }
       Response.Write("<SCRIPT>alert('Transcation completed Successfully!!!! ')</SCRIPT>");
