How to implement thousand seperator for text-boxes in ASP.NET C# (500 pt)

double value;

value = 1234567890;
Console.WriteLine(value.ToString("#,#", CultureInfo.InvariantCulture));    
// Displays 1,234,567,890      

How can we apply this to all the textboxes?

two Solutions:

1> Implement a Ajax Mask Edit Extender (Out of the Box functionality) and attach it to ur text box ,a more professional approach as it will help u if tomorrow ur site switches for different language then ur Currency Format Will Change.

2> A More easy approcah ,create a Custom Function to return a Number format

txtBox.text = ReturnFormat(NumToBeDisplayed);

string RetrunFormat(int Num)
{
  return Num.ToString("N");

}

txtBox.text = ReturnFormat(NumToBeDisplayed);
 
string RetrunFormat(int Num)
{
  return Num.ToString("N");
 
}

Hi DreamsTech,

I tried the solution that you gave. But it inserts two 0s after decimal.(e.g. 13,000.00) How can I remove those so that I get (e.g. 13,000) ?

Thanks!

Also, I would want this to happen when the cursor is out of the textbox. How to do that?
