When you're getting an error always say what line the error happens on, and use the debugger to step through your code as it will help solve these issues. If the error is on this line

C#

CustomerID = Convert.ToInt32(dtResult.Rows[0][0]),

Then chances are dtResult has no rows in it. Did you mean

C#

CustomerID = Convert.ToInt32(dt.Rows[0][0]),

instead?

Solution 4

kindly check parameters which are you passing through code are matching to tables parameters and datatype. If you are using procedure then execute it by adding parameters which are u taking @ run time..You will find out the problem easily.

Solution 1

It simply means that the number of rows is zero. Before addressing some element of the array or a collection by index, you can check up the length of it, number of elements.

Solution 3

I think its a copy/paste mistake.
look at your code and correct following line of code

change below line to

C#

CustomerID = Convert.ToInt32(dtResult.Rows[0][0]),

This line

C#

CustomerID = Convert.ToInt32(dt.Rows[0][0]),

Solution 5

Please check the row count of the "dtResult" , if it is not used by mistake else change it to dt.Rows[0][0]...

string productids = string.Empty;
DataTable dt;

if (Session["MyCart"] != null)
{
dt = (DataTable)Session["MyCart"];

tkbsonsmerchant k = new tkbsonsmerchant()
{
CustomerName = txtCustomerName.Text,
CustomerEmailID = txtCustomerEmailID.Text,
CustomerAddress = txtCustomerAddress.Text,
CustomerPhoneNo = txtCustomerPhoneNo.Text,
TotalPrice = Convert.ToInt32(txtTotalPrice.Text),
ProductList = productids,
PaymentMethod = rblPaymentMethod.SelectedItem.Text
};

DataTable dtResult = k.SaveCustomerDetails();

for (int i = 0; i < dt.Rows.Count; i++)
{
tkbsonsmerchant SaveProducts = new tkbsonsmerchant()
{

//BELOW LIEN HERE IS ERROR CAME - INDEX OUT OF RANGE EXCEPTION WAS UNHANDLED BY USER CODE - THERE IS ROW AT POSITION 0.
CustomerID = Convert.ToInt32(dtResult.Rows[0][0]),
ProductID = Convert.ToInt32(dt.Rows[i]["ProductID"]),
};
SaveProducts.SaveCustomerProducts();
}

Session.Clear();

lblTransactionNo.Text = "Your Transaction No :-" + dtResult.Rows[0][0];

pnlOrderPlacedSuccessfully.Visible = true;

sendOrderPlacedAlert(txtCustomerName.Text, txtCustomerEmailID.Text, Convert.ToString(dtResult.Rows[0][0]));

txtCustomerAddress.Text = string.Empty;
txtCustomerEmailID.Text = string.Empty;
txtCustomerName.Text = string.Empty;
txtCustomerPhoneNo.Text = string.Empty;
txtTotalPrice.Text = "0";
txtTotalProducts.Text = "0";
