view data using ID in asp.net - asp.net

Question

I want to view another page using
Response.redirect
but considering a customerID along with it. here is my button code:
protected void btnPlaceOrder_Click(object sender, EventArgs e)
{
string productids = string.Empty;
DataTable dt;
if (Session["MyCart"] != null)
{
dt = (DataTable)Session["MyCart"];
decimal totalPrice, totalProducts;
bool totalPriceConversionResult = decimal.TryParse(txtTotalPrice.Text, out totalPrice), totalProductsConversionResult = decimal.TryParse(txtTotalProducts.Text, out totalProducts);
ShoppingCart k = new ShoppingCart()
{
CustomerName = txtCustomerName.Text,
CustomerEmailID = txtCustomerEmailID.Text,
CustomerAddress = txtCustomerAddress.Text,
CustomerPhoneNo = txtCustomerPhoneNo.Text,
TotalProducts = totalProductsConversionResult ? Convert.ToInt32(totalProducts) : 0,
TotalPrice = totalPriceConversionResult ? Convert.ToInt32(totalPrice) : 0,
ProductList = productids,
PaymentMethod = rblPaymentMethod.SelectedItem.Text
};
DataTable dtResult = k.SaveCustomerDetails();
for (int i = 0; i < dt.Rows.Count; i++) // loop on how many products are added by the user
{
ShoppingCart SaveProducts = new ShoppingCart()
{
CustomerID = Convert.ToInt32(dtResult.Rows[0][0]),
ProductID = Convert.ToInt32(dt.Rows[i]["ProductID"]),
TotalProducts = Convert.ToInt32(dt.Rows[i]["ProductQuantity"]),
};
SaveProducts.SaveCustomerProducts();
}
Response.Redirect("Admin/OrderDetails.aspx?Id={0}");
What it does is that it gets all the user input then in the end, i want to show to the user his/her order summary. As you can see, i am trying to use Response.Redirect.
The problem is i want to use the current customerID when i use the
Response.Redirect("Admin/OrderDetails.aspx?Id={0}");
any tricks on this?

Answer 1

You have CustomerID already. Substitute {0} before redirecting with that value
var customerId = Convert.ToInt32(dtResult.Rows[0][0]);
Response.Redirect(String.Format("Admin/OrderDetails.aspx?Id={0}", customerId.ToString()));
