[Guest]

hey all,

is there a way to persist a client-side variable between postbacks?

thanks,

Rodchar,

You may store it in a cookie, in a database, in a text file, in viewstate,
or in a session variable. Which is the best would depend on the information
being stored.

how do i store a client-side variable in viewstate or session? i'm not sure
of the exact syntax to do this?

rodchar,

To store in viewstate:

Viewstate.Add("MyString", "This is my variable")
Viewstate.Add("MyInt", 13)

To store in session:

Session.Add("MyString", "This is my variable")
Session.Add("MyInt", 13)

Where MyString and MyInt are the keys and then any object may be added as
the value.

To retrieve:

Dim MyString As String = Viewstate.Item("MyString").toString
Dim MyInt As Int32 = CType(Viewstate.Item("MyInt"), Int32)

Dim MyString As String = Session.Item("MyString").toString
Dim MyInt As Int32 = CType(Session.Item("MyInt"), Int32)

You don't. Use either a cookie or a hidden textbox.

I understood the OP asked how to do it from client side.

Yes,

But if he posts back... It's no longer just client side is it? So what's the
point of limiting it to client side then? I'm just trying to understand why
not use a "server side solution". Of course if the variable needs to be
accessed again client-side then you're right, a hidden field or a cookie is
about the only choice. (Unless you get into Ajax).

Using an hidden field you can transmit back and forth the value...

Where do you need this exactly ? (you could use a cookie if you need this
only client side and find this acceptable).

textbox which i converted to run at server and that seem to have work well,
