Ok, but you didn't answer my question. Answer that and maybe I can assist you.

Hmm, can you post a complete example to reproduce your problem? That way, I can debug it on my local computer and maybe give you some insight.

Until then, try this. Replace these:

dataGridView2.InvokeRequired
dataGridView2.Invoke

with these:

this.InvokeRequired
this.Invoke

Not sure that will work, but it's worth a try.

this.InvokeRequired<br />
this.Invoke

doesn't work (i don't need invoke "this" object)

and about examp

give me your email, and i'll send it to you

Either strip the zeros off the string or use Math.Round

JYIS, they aren't there! They don't exist!

Edit: I posted that before I saw that you were using Decimal rather than Double.

ToString:

"
The return value is formatted with the general numeric format specifier ("G"), and the NumberFormatInfo object for the current culture.
"

G:

"
The exception to the preceding rule is if the number is a Decimal and the precision specifier is omitted. In that case, fixed-point notation is always used and trailing zeroes are preserved.

The trailing zeroes? Yes they do. See here.

Just a minor point - in numeric terms, 1120.00120000 is exactly the same as 1120.0012. If you're doing a calculation using a decimal then it doesn't make much sense to round trim it.

Indeed, though there is a difference in some situations, such as when using ToString(). Try running this:

string strD = "192.0205000";
Decimal D = Decimal.Parse(strD);
MessageBox.Show(D.ToString());
// Outputs: 192.0205000

I never knew that the Decimal data type actually maintains the trailing zeroes. D'Oh! | :doh:

Excellent question! ~~And thanks for providing the answer.~~ I had no idea the Decimal data type stores trailing zeroes.

Just a bit of friendly advice... avoid using uppercase when not necessary, don't beg for help, and don't shorten words (e.g., "PLZ") except for common acronyms. To many people here at Code Project, it appears unprofessional. Other than that, though, great question. Thumbs Up | :thumbsup:

EDIT: It appears your answer is incorrect.

This is merely a quirk of the "G" format; when ToStringing a Decimal, use something along the lines of d.ToString ( "#.###############" ).

AspDotNetDev28-Apr-10 19:24

28-Apr-10 19:24

Good call. One can also use:

d.ToString("G29");

That's basically what the default is and I don't think it works.

After reading what everybody has said, I think you want this:

Decimal d = Decimal.Parse(Decimal.Parse("192.0205000").ToString("G29"));
