How to access the values of hidden fileds of form A in form b?
Sessions or querystrings should not be the option! I heard we can access any control of one form in another using persistpage class in 2.0 however iam using 1.1 and c# can i access these hidden fields?

What's done in .NET 2.0 is that an object instance of another page can be created, and that object consumes the data in the Request.Form collection so that you can access the values using that page object.
All the data that was posted to the page is available in the Request.Form collection. You can access those values directly, there is no need to instantiate another page object to do so.

Hi Friend:
Here is code for getting child hashtable value.
//Make main Hash table
Hashtable mainHashTable = new Hashtable();
//Make child Hash Table
Hashtable childHashTable = new Hashtable();
//Add child hash table value
childHashTable.Add("ChildValue", "Mubashir");
//Add child hash table to main hash table
mainHashTable.Add("HashTable", childHashTable);
//Get Child Hash table value
((Hashtable)mainHashTable["HashTable"])["ChildValue"].ToString()

but i have many walu in child hash table like this:-
Dim ConfId As String
Dim meesage As String
Dim SinglNode As System.Xml.XmlNode = xRequests.SelectSingleNode("/cwaEvents/conference")
ConfId = SinglNode.Attributes("confId").InnerText
Dim SinglNode1 As System.Xml.XmlNode = xRequests.SelectSingleNode("/cwaEvents/conference/messageReceived/message/content")
If SinglNode1.InnerText <> "" Then
meesage = SinglNode1.InnerText
'M_MessageTextHTAble = M_MessageHTAble.Item(ConfId)
M_Messagecounter = M_Messagecounter + 1
M_MessageTextHTAble.Add(M_Messagecounter, meesage)
M_MessageHTAble.Remove(ConfId)
M_MessageHTAble.Add(ConfId, M_MessageTextHTAble)
End If
Return M_MessageHTAble

Step 1 :
Get the Fist M_MessageTextHTAble from the M_MessageHTAble by ConfId
Step 2 :
Get the all item from M_MessageTextHTAble by For each statement

This code works for you. You can add different items in child node.
These item can be of any type.
All you need is type casting.
Lets suppose you added SinglNode of XMLNode type in child hash table.
You shall use this line for getting that object
((XMLNode)((Hashtable)mainHashTable["HashTable"])["ChildValue"]))
This line first get the value of child table then convert it to XMLNode.
You can add multiple different objects in hash table.
//Make main Hash table
Hashtable mainHashTable = new Hashtable();
//Make child Hash Table
Hashtable childHashTable = new Hashtable();
//Add child hash table value
childHashTable.Add("ChildValue", "Mubashir");
//Add child hash table to main hash table
mainHashTable.Add("HashTable", childHashTable);
//Get Child Hash table value
((Hashtable)mainHashTable["HashTable"])["ChildValue"].ToString()

This helpful to extract the whole list of key & values when debugging:
Public Shadows Function ToString(ByVal hashTable As Hashtable) As String
Dim s As String = String.Empty
Dim enumerator As IDictionaryEnumerator = hashTable.GetEnumerator()
While (enumerator.MoveNext())
s += enumerator.Key & ": " & enumerator.Value & ControlChars.NewLine
End While
Return s
End Function

In VB semicolon is not required.
Instead you need to place the semicolon after your alert statement.

I wrote the code like this
Dim con3 As New SqlConnection
con3.ConnectionString = "workstation id=R21;packet size=4096;integrated security=SSPI;data source=R21;persist security info=False;initial catalog=Test"
Dim ID As String = "select Cand_Id from Feedback where Cand_Id in(select Max(Cand_Id) from Feedback )"
con3.Open()
Dim cmd3 As New SqlCommand
cmd3.CommandText = ID
cmd3.Connection = con3
cmd3.ExecuteNonQuery()
con3.Close()
Response.Write("alert('" + ID.ToString() + "')")
But in the alert box its showing the output as the entire query not thr id
OUT PUT = select Cand_Id from Feedback where Cand_Id in(select Max(Cand_Id) from Feedback )
But i want my out put to be 1 , 2 .... like this

This is happening because the text what you have stored in string ID is the same what you are getting. What you need to do is to store the data (what sqlquery is returning) in dataset and then use dataset to display the data.

Inspite of that take it as this:
ID = ds3.Tables[0].Rows[0]["Cand_Id"].ToString();

Is ID is of string type?
put like this:
string ID = ds3.Tables[0].Rows[0]["Cand_Id"].ToString()

Thanks Apurva for being so patient. Yes its of type string
In the statement ds3.Tables[0].Rows[0]["Cand_Id"].ToString(). Its asking for identifier expected in statement
ds3.Tables[0]
below[0]. Is is a synatx prob i am using VB
Prakash Mishra(Banglore,India)

In vb.net it will be like this:
ID = ds.Tables(0).Rows(0)("ID").ToString()
