Answer / guest

no we cant transfer data from one page to another page
using viewstate.
becouse in viewstate we can store only page level
information

Answer / abhinav saxena

Its right we cannot transfer the value from one page to
another using viewstate. Viewstate has the limit only on
one page. For transferring values we can use session or
querystring and interesting for more value transfer store
the values in datatable and store the table in a session.

Answer / william niver

Yes, you can get the PreviousPage ViewSate.

I have created two pages (Default.aspx and LandingPage.aspx)

Default.aspx has a LinkButton with a PostBackUrl pointing
to LandingPage.aspx.

Code Behind for Default.aspx:

Partial Class _Default
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e
As System.EventArgs) Handles Me.Load
ViewState("MyValue") = "I am a test value"
End Sub

Public Function GetViewState() As System.Web.UI.StateBag
Return ViewState
End Function

End Class

Code Behind for LandingPage.aspx:

Partial Class LandingPage
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e
As System.EventArgs) Handles Me.Load
If PreviousPageViewState IsNot Nothing Then
If PreviousPageViewState("MyValue") IsNot
Nothing Then
'Value is retrieved from the PreviousPage
ViewState
MyBase.Controls.Add(New LiteralControl
(PreviousPageViewState("MyValue")))
End If
End If
End Sub

Private ReadOnly Property PreviousPageViewState() As
StateBag
Get
Dim ReturnValue As System.Web.UI.StateBag =
Nothing
If PreviousPage IsNot Nothing Then
Dim MyTypeObj As Object = DirectCast
(PreviousPage, Object)
For Each MethodObj As Reflection.MethodInfo
In PreviousPage.GetType.GetMethods()
If MethodObj.Name = "GetViewState" Then
ReturnValue = MethodObj.Invoke
(MyTypeObj, Nothing)
Exit For
End If
Next
End If
Return ReturnValue
End Get
End Property

End Class

Answer is 'NOOOOOOO....'

Answer / anil pandya

Yes, We can transfer one page data to another page using
viewstate,

The Way :-

The whole page data is stored in viewstate when you do a
page submit, at this point if you do server.transfer to
another page, it is like a postback on same page, you can
access both page data in view state.

To access the previous page data you have to use

System.Web.UI.Page prevPage = this.PreviousPage;

now all your controls are available with the same state they
were posted.

Answer / guest

View state is page level Access state managemenet
so viewstate object is available only after page_init() and
before page_load().

so we cannot pass it from one page to other page as a part
of request or any more......

Answer / vengatesh

not possible

Answer / sujata

A) yes we can do it by
1)Server.transfer(“Default2.aspx”);
2)with postbackURL property in the button event.

Source Page:

protected void Page_Load(object sender, EventArgs e)
{
if (ViewState["NameOfUser"] != null)
Label1.Text = ViewState["NameOfUser"].ToString();
else
Label1.Text = "Not set yet...";

}
protected void Button1_Click(object sender, EventArgs e)
{
ViewState["NameOfUser"] = TextBox1.Text;
Label1.Text = TextBox1.Text;
Server.Transfer("Default2.aspx"); //Response.Redirect("Default2.aspx");(Cannot do wit response.redirect")

}

Target Page:

protected void Page_Load(object sender, EventArgs e)
{
Response.Write(((Label)PreviousPage.FindControl("Label1")).Text);
Label1.Text =" " + ((Label)PreviousPage.FindControl("Label1")).Text;

}
