Thousand Seperator in TextBox

[freshonlineMax]

Hello Please help me to show thousand seperator in textbox like: 25000000>25,000,000 I found a formul like below at textchanged event: string myStr = textBox1.Text; TextBox1.Text = myStr.FormatString("#,###"); But it causes error at : Int a = Convert.ToInt16(TextBox1.Text); I want to seperate numbers in textbox anyway. I couldn't use "MaskedTextBox" Please help me. Regards

You could remove the "," before parsing (btw why aren't you using short.Parse?)

[0x3c0]

You can replace FormatString with ToString("N0"). And there are at least two problems with your parsing code. First of all, you convert TextBox1.Text to a 16-bit integer, then store it as a 32-bit integer. This constrains it to the value 65,535. That's far too small for the value you want. Additionally, you're using Convert.ToInt16. Use the method int.Parse() instead.

Hi, you can tell Parse and TryParse what it is you want to allow, e.g.:

int val;
bool OK=int.TryParse("12,345", NumberStyles.AllowThousands, null, out val);

Hello Tanks for your help. I used your code like below : Int64 val; bool ok; ok = Int64.TryParse(TextBox1.Text, NumberStyles.AllowThousands, null, out val); TextBox1.Text = Convert.ToInt64(val.ToString()).ToString("#,###"); The problem accures after typing more than 4 numbers. Because cursor qoes to the left side of numbers, For example i want to type 12345, after typing 4 in typing 5 it TextBox shows : 51,234 Can you help me on this? Regards

Hi again I solved it by below code: TextBox1.Select(TextBox1.Text.Length, 0); Bye

[Morteza Karimian Kelishadrokhi]

use this code: by this code,your problem is ok

private void textBox1_TextChanged(object sender, EventArgs e)
{
try
{
string ss = textBox1.Text.Replace(",", "");
int d = int.Parse(ss);
string gg = String.Format("{0:###,###,###}", d);
textBox1.Text = gg;

           textBox1.SelectionStart = textBox1.Text.Length;
       }
       catch
       {
       }

   }

try { string ss = textBox1.Text.Replace(",", ""); int d = int.Parse(ss); string gg = String.Format("{0:###,###,###}", d); textBox1.Text = gg; textBox1.SelectionStart = textBox1.Text.Length; } catch { }
