Session array

Sandraa

Hi all, somebody knows how create a array multi-dimensional with session variables. I have it:

Session("Preguntas") = LPH.ObtenerTest(Session("Articulo"), Session("Nivel"))

where it session is a table and I want to add the result of client into other session array but with 2 columns, something similar to

Session("ArrayRespuestas")(Session("i"), 1) = "1"

. I use session variable because when the user make click into button I receive a postback and lost my original select (LPH.ObtenerTest(Session("Articulo"), Session("Nivel"))) that is a procedure that return a select random with 2 parameters. If I use

If Not Me.Page.IsPostBack Then

and put my select into later (the second page_load) doesn't load my select and when I call to

Preguntas.Rows(i)("Respuesta1")

I received a error where told me that I must first create a object. Thanks for all.

The below code allows a multi-dimensional array to be stored in the session state. See if you can adapt this to fit your use. Good luck.

private void StoreToSession()
{
string[,]initialArray={"A","B"};
Session["sessionvalue"]=initialArray;
}

private void ReteriveFromSession()
{
string[,]resultantArray=(string[,])Session["sessionvalue"];
TextBox1.Text=resultantArray[0,0].ToString();
TextBox2.Text=resultantArray[0,1].ToString();
}

Doesn't work because the postback empty my array when I push btton. I have when load the first ask (is a test of 25 ask):

Public Ar1(25, 1) As Integer

Procedure of load ask

                Ar1(Session("i"), 0) = Session("Preguntas").Rows(Session("i"))("Id\_Pregunta")
                Session("ArrayRespuestas") = Ar1

later when button_onclick:

Dim respuesta As Integer
If RadioButton1.Checked = True Then respuesta = 1
If RadioButton2.Checked = True Then respuesta = 2
If RadioButton3.Checked = True Then respuesta = 3
If RadioButton4.Checked = True Then respuesta = 4
If RadioButton5.Checked = True Then respuesta = 5
Ar1(Session("i"), 1) = respuesta
Session("ArrayRespuestas") = Ar1
Session("i") = Session("i") + 1

This work without errors, but when I try to recovery the datas of array I only get the value present Ar1(Session("i"), 1) but I lost the value Ar1(Session("i"), 0) because was added before of push button and later the postback empty my array. Good, realty is when I put Session("ArrayRespuestas") = Ar1 is when I clear my session array. I believe that the solve is to search like get not postback when click button. I accept advisers boys :)

Solved I put into page_load

    If Not Me.Page.IsPostBack Then
        Session("i") = 0
        Dim Ar1(25, 1) As Integer
        Session("ArrayRespuestas") = Ar1
    End If

Then only I define the array a time :) Thanks for your help ;-)
