Hey guys-

I am trying to do a simple custom web control. I want a textbox with a tag
property that maintains it's tag (if programmatically changed) between page
requests. How can I get the tag property to maintain its state?

-----------------------------------------------------

Imports System.Web.UI.WebControls

Public Class TagTextbox
Inherits TextBox
Private strTag As String
Public Property Tag() As String
Get
Tag = strTag
End Get
Set(ByVal str As String)
strTag = str
End Set
End Property

End Class

----------------------------------------------

thanks,

Super simple, Jay:

Public Property Tag() As String
Get
Dim o as Object =3D ViewState("tag")
        If o Is Nothing Then
            Return String.Empty
        End If
        Return CStr(o)
End Get
Set(ByVal str As String)
ViewState("tag") =3D str
End Set
End Property

You can also search help for "ViewState"-- there's an example the shows =
exactly this.

Susan,

thanks for the tip! That is easy. Is there much overhead associated with
doing this? I mean, should I create properties that maintain state with
reckless abandon in this way, or should it be kept to a minimum to get the
job done...?

thanks,

Jay

Your users will appreciate restraint, but properties with simple types =
(ints, strings) usually don't contribute much to the bottom line, =
viewstate-wise. I'd avoid putting big, complex objects (like DataSets) =
into viewstate. But in controls we ship, most of the properties that =
are commonly set have their values round-tripped in viewstate.

hth,
Susan
