need help with a string manipulation.I am trying to create few dynamic controls and once they are rendered I need to save the information that was entered into these dynamic fileds. For instance when I create 3 radio button dynamic controls I get the ID of this controls as rdb29OPT0 rdb30OPT1 rdb31OPT2 .... Now I am trying to manipulate the the above string and just try getting the 29, 30, 31 from them. Can some one help me with how do I just the values 29 and remove rdbOPT1 for the first string? Thanks in advance -L Take a look at the "mid" funtion.

rdb1234OPT1234 ! out of which I just need the numerical value that is in between 'rdb' and 'OPT1234' I am looking for kind of a method that could rdb and also the word that starts with OPT Hope this gives a little inside of it.

middle. To get the value in at the end you can use the following: s.Substring(s.IndexOf("OPT") + 3) And if you want the number in the middle you can use the following: s.Substring(3, s.IndexOf("OPT") - 3) Learner wrote: Show quoteHide quote > well there could be many values down the line for instance > rdb1234OPT1234 ! > out of which I just need the numerical value that is in between 'rdb' > and 'OPT1234' > > I am looking for kind of a method that could rdb and also the word that > starts with OPT > > Hope this gives a little inside of it. > Thanks > -L > Mythran wrote: > > "Ahmed" <ahmed1***@gmail.com> wrote in message > > news:1151596865.645830.139100@d56g2000cwd.googlegroups.com... > > > Take a look at the "mid" funtion. > > > > > > Ahmed > > > Learner wrote: > > >> Hello, > > >> I am trying to create few dynamic controls and once they are rendered > > >> I need to save the information that was entered into these dynamic > > >> fileds. > > >> > > >> For instance when I create 3 radio button dynamic controls I get the ID > > >> of this controls as > > >> > > >> rdb29OPT0 > > >> rdb30OPT1 > > >> rdb31OPT2 > > >> ... > > >> > > >> Now I am trying to manipulate the the above string and just try getting > > >> the 29, 30, 31 from them.

Thanks for the help. s.Substring(3, s.IndexOf("OPT") - 3) works in my case. I didn't know that I can use the IndexOf to get the exact position of particular charecter in a string. Thats what I was looking for. thanks again, -L Ahmed wrote: Show quoteHide quote > I noticed that the number at the end is the same as the number in the > middle.

that case. There are plenty of tutorials on RegEx available.

Mythran Hello Learner,
Regex is overkill and overly complex. Why not just store the number in the control's .Tag property. Or derive a new control from radiobutton and add a .Identifier property. -Boo Show quoteHide quote > Hello, > I am trying to create few dynamic controls and once they are > rendered > I need to save the information that was entered into these dynamic > fileds. > > For instance when I create 3 radio button dynamic controls I get the > ID of this controls as > > rdb29OPT0 > rdb30OPT1 > rdb31OPT2 > ... > Now I am trying to manipulate the the above string and just try > getting the 29, 30, 31 from them.
