substring()

I'm assuming this is the value or some other property of a place holder so why not try:

((ControlType)PlaceHolder1.FindControl("ControlName")).Property (usually .Text or .SelectedValue)

use String.Split on "="

str="asDfsl00_PlaceHolder1_default_ctl01_ctl43_radiobutton1&info_id=5634&Age=17"

Dim arrValues() as string
Dim id, age as string

arrValues=str.Split("=")
id=arrValues(arrValues.Length-2)
age=arrValues(arrValues.Length-1)

actually you'll need


Dim arrValues() As String
        Dim str, infor_id, age As String

        str = "asDfsl00_PlaceHolder1_default_ctl01_ctl43_radiobutton1&info_id=5634&Age=17"

       
        arrValues = Str.Split("=")
        info_id= Replace(arrValues(arrValues.Length - 2), "&Age", "")
        age = arrValues(arrValues.Length - 1)

using C#:

string str = "asDfsl00_PlaceHolder1_default_ctl01_ctl43_radiobutton1&info_id=5634&Age=17";
string[] arrValues = Str.Split("=");
string info_id = Replace(arrValues(arrValues.Length - 2), "&Age", "");
string age = arrValues(arrValues.Length - 1);

If the case is that it isn't a control inside a control you can do:

string someString = "asDfsl00_PlaceHolder1_default_ctl01_ctl43_radiobutton1&info_id=5634&Age=17";

someString = someString.Substring(someString.IndexOf("info_id=") + 8);

string info_id = someString.Substring(0, someString.IndexOf("&"));
string Age = someString.Substring(someString.IndexOf("&") + 1);

sorry:

string Age = someString.Substring(someString.IndexOf("&") + 1);

should be:

string Age = someString.Substring(someString.IndexOf("Age=") + 4);



but once again if you are accessing controls in this placeholder, it is best to type case a findcontrol on the control ID you want to access ie:

((TextBox)PlaceHolder1.FindControl("Age")).Text

Yzlat:

Error      2      Argument '1': cannot convert from 'string' to 'char[]'      

Error      3      The name 'Replace' does not exist in the current context      

Error      4      'arrValues' is a 'variable' but is used like a 'method'      

Error      5      'arrValues' is a 'variable' but is used like a 'method'

>but once again if you are accessing controls in this placeholder, it is best to type case a findcontrol on the >control ID you want to access ie:

thanks but i'm not finding any control

but in fact i'm adding into the string and from there i'm extracting.

Where is the string being stored? is it the text or the id of the Panel?

its storing in the string

try replacing

string[] arrValues = Str.Split("=");

with

string[] arrValues = str.Split(new char[] {'='});

is it the safe side of doing?

string str = "asDfsl00_PlaceHolder1_default_ctl01_ctl43_radiobutton1&info_id=5634&Age=17";
                    string[] arrValues = str.Split(new char[] { '=' });
                    string info_id = Replace(arrValues(arrValues.Length - 2), "&Age", "");
                    string age = arrValues(arrValues.Length - 1);

Error      1      The name 'Replace' does not exist in the current context
Error      2      'arrValues' is a 'variable' but is used like a 'method'
Error      3      'arrValues' is a 'variable' but is used like a 'method'

strange... can you post all your code?

have you tried this yet:

string someString = "asDfsl00_PlaceHolder1_default_ctl01_ctl43_radiobutton1&info_id=5634&Age=17";

someString = someString.Substring(someString.IndexOf("info_id=") + 8);

string info_id = someString.Substring(0, someString.IndexOf("&"));
string Age = someString.Substring(someString.IndexOf("Age=") + 4);

I used Replace like in VB.NET before. Here is C# version

strickdd, yes your approach word

but just want to get some opinion

is that the safe way of extracting?
