The solution 1 is good. But see solution 2 regarding the mid point rounding.
Thank you.

Solution 2

The Parse method of Decimal explained here
Decimal.Parse Method (String)[^]
and the Round method of Math class explained here
Math.Round Method (Decimal, Int32, MidpointRounding)[^]
can be used as follows:

VB

getdetails.Parameters.Add("@dd_sell", SqlDbType.Float).Value =
Math.Round(decimal.Parse(txt_dd_sell.Text),2,MidpointRounding.AwayFromZero)

By default the Round method uses MidpointRounding.ToEven enumeration value, which means that if the value to be rounded is 2.555 it will be rounded off to 2.56 and if it is 2.565 then also it will be rounded off to 2.56 as 5 is the mid point. If the MidpointRounding.AwayFromZero is used then the above values will be rounded off to 2.56 and 2.57 respectively.
