Problem: ViewState

[Genocide]

I am trying to write a web control, but I've run into a major snag.

I cannot find my ViewState data!

Below is a sample of some code I wrote. It worked for a few hours.

    Protected Overrides Sub OnInit(ByVal e As System.EventArgs)
        If Not Me.Page.IsPostBack Then
            'First creation of control set default value
            ViewState.Add("IsSearch", True)
        End If
    End Sub

    Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
        If ViewState("IsSearch") Then
           'Do something
        Else
           'Do something else
        End If
    End Sub

I initialise the ViewState with a value when it is first created, and the OnLoad event executes as desired (runs True section). However, when the page reloads, as postback event, the OnLoad event code fails (runs False section). The failure occurs because IsNothing(ViewState("IsSearch")) = True.

Am I doing something wrong here or is Microsoft?
