How do I add thousand separators in default number format in ssrs?

Question

I got a bunch of numbers in different unit. I need to add thousand commas separators without affecting the decimal values. I want the decimal values to display as it is. I want the number format in following way

• 10000 ---> 10,000
• 56789.125 ---> 56,789.125
• 2000.1231 ---> 2,000.1231

Answer 1

From SSRS (right click text box-expression), specify this expression value:

=Format(Fields!ColumnName.Value, "#,###0.####")

This will format your number into maximum 4 digits on decimal point, depending on presence of decimal values after the point.

If you need to format number value from C# code before adding to SSRS, use:

String.Format("{0:#,###0.####}", ColumnName.ToString()); // assume ColumnName is your number variable here

Answer 2

I found this to be the simplest way:

myInteger.ToString("N0")

Or you can do like so:

myInteger.ToString("#,##0.00");

Try This:

static string FormatNumber(int num)
 {    
    return num.ToString("#,0");
 }
