where have you defined 'table'?

Your table needs five columns, how many does it have?

meraj ali 6-Mar-23 9:02am

Table.Columns.Add("Num", typeof(int));
Table.Columns.Add("Product", typeof(string));
Table.Columns.Add("qty", typeof(int));
Table.Columns.Add("uprice", typeof(int));
Table.Columns.Add("totprice", typeof(int));
Table.Rows.Add(num,Product,qty,uprice,Totpric);
order add in to Gv but when enter anther product first going to clear

Solution 1

The error says that your table does not have that many columns. Fix your code so that it does have enough columns.

num = num + 1;
qty = Convert.ToInt32(QtyTb.Text);
totprice = qty * uprice;

Add these lines here          
                DataTable table = new DataTable();
                table.Columns.Add("Num", typeof(int));
                table.Columns.Add("Product", typeof(string));
                table.Columns.Add("qty", typeof(int));
                table.Columns.Add("uprice", typeof(int));
                table.Columns.Add("totprice", typeof(int));
then continue your code

table.Rows.Add(num,product,qty,uprice,totprice);
OrdersGv.DataSource = table;
flag = 0;
