Your validation easly made by various string functions,First you valid
the data then you can format the data as you like.
First input data Split into three value , Assume user give 45.0003
in the LLtextBox
Then you can split the value into two look the following C# code
string[] s ;
s = LLtextBox.Text.Split('.');
int Longitude= Convert.ToInt16(s[0]); //45
int Latitude= Convert.ToInt16(s[1]); //0003
//then again latitude value into two using substring functions
string v1= s[1].Substring(0, 2); //00
string v2= s[1].Substring(2); //03
if user give less then three digit value eg 87
call above split function
now s[0] contain 87
but s[1] contain Null value ,then you can assign default value
Then you can format the data using string functions like insertchar
