How do you perform addition of two columns in Aspnet?

Answer 1

In ASP.NET, you can perform addition of two columns by retrieving the data from a data source, such as a database, and then processing it in your code. For example, if you have a DataTable, you can loop through its rows and sum the values of the two columns using a simple loop. Here's a quick example in C#:

decimal total = 0;
foreach (DataRow row in dataTable.Rows)
{
    total += Convert.ToDecimal(row["Column1"]) + Convert.ToDecimal(row["Column2"]);
}

This will give you the total of the two columns for all rows in the DataTable.
