Question

I am trying to ensure that the text in my control derived from TextBox is always formatted as currency.

I have overridden the Text property like this.

   public override string Text     {         get         {             return base.Text;         }         set         {                             double tempDollarAmount = 0;             string tempVal = value.Replace('$', '').Replace(',','');             if (double.TryParse(tempVal, out tempDollarAmount))             {                 base.Text = string.Format('C', tempDollarAmount);             }             else             {                                  base.Text = '$0.00';             }                         }     } 

Results:

• If I pass the value ‘Text’ (AmountControl.Text = ‘Text’;) , the text of the control on my test page is set to ‘$0.00’, as expected.
• If I pass the value 7 (AmountControl.Text = ‘7’;) , I expect to see ‘$7.00’, but the text of the control on my test page is set to ‘C’.

I assume that I am missing something very simple here. Is it something about the property? Or am I using the string format method incorrectly?

Answer 1

Instead of ‘C’ put ‘{0:c}’
