asp.net vb.net inherits textbox runtime

[CsaaGuy]

Hi, I created a class in ap.net using vb.net that inherits from
Textbox. I added a few of my own properties and methods, set it up to
appear in the toolbox. And have used it. My properties that appear on
the toolbar work fine at design time. I set them at design time and all
works fine. I can access them later, they retain value and work.

However, when I try to set them at run time, they set but when the page
posts back, the data has reverted back the defaults. My user properties
are not retaining value during the postback. SOOOOOO the question is
how do I get my user properties to retain values during postback if set
at runtime? Thanks.

Store your custom values in ViewState.

Control Property Sample:

VB.Net:
Public Property IntValue() As Integer
Get
Dim i As Object = ViewState("IntV alue")
If i Is Nothing
Return 0 ' Default Value I Want Set
End If
Return CInt(i)
End Get
Set
ViewState("IntV alue") = Value
End Set
End Property

C#:
public int IntValue
{
get {
object i = ViewState("intV alue");
if (i == null) {
return 0; // Default Value I Want Set
}
return int.Parse(i.ToS tring());
}
set {
ViewState("intV alue") = value;
}
}
Off top of head :)

HTH,
