converting to decimal

Jes Sie

9y7.5k.NET

I need assistance again ;( . I have this code snippet below which converts the textbox to a decimal:

private void ComputeTotalPremium()
{
try
{
int persons = Convert.ToInt32(txtTravellingPersons.Text);
decimal premium = Convert.ToDecimal(lblPremium.Text);
decimal Total;
Total = persons * premium;
txtTotalPremium.Text = Total.ToString("N2", CultureInfo.InvariantCulture);
}
catch (Exception ex)
{
if (ex is FormatException)
{
}
else
{
throw ex;
}
}
}

The value of txtTravellingPersons.Text is 1.

The original value of lblPremium.Text is 16.00, but when the value was converted to decimal (decimal premium) the 16.00 becomes 1600.

Please note that this piece of code was working ever since I'm using it but now it failed. Thanks for any assistance.

hi,

I think instead of N2 you ave to give F2 for decimal

try instead of

txtTotalPremium.Text = Total.ToString("N2", CultureInfo.InvariantCulture);

txtTotalPremium.Text = Total.ToString("F2");

Okay Hold On,

Then try VS 17, or else reinstall you VS15.

Thanks you.

Guys, thank you for all your effort. I guess the problem is my visual studio. I tried my code on the other computer and it worked.

Thank you, Sundar and Ramesh.

Still the same Sundar. I copied and pasted your code as seen below:

Hai,

OKay, then here I have pasted a code to convert to Decimal, Try this function. Paste this code in class and call the function will converting and let me to know what the output is,
public static Decimal ToDecimal(object num)

        {

            try

            {

                return decimal.Parse(num.ToString());

            }

            catch (Exception)

            {



                return 0;

            }

        }

Call the ToDemical method  while you convert.
Convert.ToDecimal(lblPremium.Text); change Convert.ToDecimal to

SampleClass.ToDecimal(),

paste this ToDecimal Method in that Class (In my case SampleClass) .

Thanks for all your responses. Sundar, I don't have a JS function relating to the affected textbox. The only JS function I made is the calendar but it points to a different textbox. I debug my application and below are the screenshots:

The value of the lblPremium.Text is from the database and the data type is decimal. From the original value of 16.00, it became 1600 after it converted to decimal. So, when I multiply the persons to the premium, it gives a different answer. It didn't even reach the Culture.Info yet.

I am using VS 2015.

Hi Sundar,

In text box we can store only string values and We cannot us JS validations in this application. Because its winform application. not a windows application
Sundaram Subramanian9y ago
txtTotalPremium.Text , you are assign the value to String. allocated the value as decimal.

Hi Hold,

Remove the cultureinfo.invariantculture line and try again
Sundaram Subramanian9y ago
Have you set any JS Function or any round off function for that particular textbox ?.

Or

any JS validations to get only numbers likewise ?.
