The problem is you're trying to put text into a field that iwll only have decimal values. Unless you redesign your data structure, there is no solution to your problem.

Before cascading the number, you need to validate the null and the type of variable as follows:

C#

if (dataRow.IsNull("Amount") or (dataRow["Amount"] as Decimal) != null)
{
  decimal result = Convert.ToDecimal(dataRow["Amount"-);
}
