In this case the Type of the value to be assigned to the NumericUpDown Control is important to specify.

If what you retrieve from the database is a Double, or string, it will require conversion to Type Decimal; if it's an Int, it will not.

on top of ProgramFox solution....

another simple and common way is like

Solution 1

Instead of this:

C#

s5 = dr[6].ToString();

Try this:

C#

s5 = dr.GetInt32(6);

You also need to change the type of s5 from string to int.

If the value in the database is not an int, but a double, use GetDouble, and if the value is a decimal, use GetDecimal.
