Don't do it. At least use masked edit control.
(You did not tag your application tag, so no more detailed answer.)

It's important to know exactly when you need to check the contents of the TextBox.

Do you want to check the contents every time two characters have been entered ? Or is there some behavior by the user that will trigger checking the contents ?

If checking is triggered by the user, then validating the text content is easier.

C#

formatmask(string str)
{
st=st.Trim();
if(st.Length>0 && st!=null)
{
if(!st.Contains('.'))
{
st=st+ '.';
st=st.PadRight(st.length+4 .'0');
}
else
{
string[] ds=st.split('.');
string aftervalue=ds[1].ToString();
if(aftervalue.Length<=4)
{
aftervalue=aftervalue.PadRight(4,'0');
}
st=ds[0].ToString()+"."+aftervalue;
}
}
rturn st;
}
}



protected void txt_TextChanged(onject sender,Eventraggs e))
{

txtformat.text=formatmask(txtformat.Text);
}
