Solution 1

The Value property of a NumericUpDown is not a string - it's a decimal value, so you don;t need to try and parse it.
Equally, it can be set to be always a valid integer by leaving the DecimalPlaces property at zero - all you need to do then is cast it to an int

so basically just remove TryParse and keep int

OriginalGriff 5-Feb-14 11:00am

Well, yes - but you don;t need the if test at all, because the user can't enter an invalid value! :laugh:

Solution 2

The value of a NumericUpDown is always a decimal, never a string. So you'll need to cast it to an int:

C#

int MINLENGTH = (int)numericUpDownLowerLimit.Value;
int MAXLENGTH = (int)numericUpDownUpperLimit.Value;
