当我选中复选框并在数量上写下数量的文本数量然后是那个textboes数量动态生成文本已更改。当我在动态文本框中编写序列号并插入数据库时。在数据库中，没有插入正确的序列号。这是我的插入代码
when i m checking the checkbox and write the number of quantity in quantity textboes then that number of textboes generating dynamically on text changed. when i write the serial no in the dynamic textboxes and insert into the database. In database the correct serial number is not inserting. this my insert code
protected void Button2_Click(object sender, EventArgs e)
{
for (int i = 0; i < GridView1.Rows.Count;i++ )
{
Label lab = (Label)GridView1.Rows[i].FindControl("Label1");
Label ColTotal = (Label)GridView1.FooterRow.FindControl("Label9");
TextBox quantity = (TextBox)GridView1.Rows[i].FindControl("TextBox2");
TextBox TAmount = (TextBox)GridView1.Rows[i].FindControl("TextBox3");
string amount = quantity.Text;
DropDownList ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
CheckBox chk = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("Checkbox1");
if (chk.Checked == true)
{
if (quantity.Text != "")
{
for (int j = 0; j < Convert.ToInt16(quantity.Text); j++)
{
con.Open();
string query1 = "insert into Inventory ([Invoice Number],Product,[Serial Number],Amount,Status) values('" + TextBox5.Text + "', '" + lab.Text + "','" + Request.Form["Textbox" + j.ToString().Trim()] + "','" + Convert.ToInt32(TAmount.Text) / Convert.ToInt32(quantity.Text) + "','" + ddl.SelectedValue + "')";
SqlCommand cmd = new SqlCommand(query1, con);
cmd.ExecuteNonQuery();
con.Close();
}
}
con.Open();
string query = "insert into FSPL_Inventory ([Invoice Number],[Date],[Total Amount]) values('" + TextBox5.Text + "','" + Label7.Text + "','" + ColTotal.Text + "')";
