    Checkmark not saving state on round trip

    Even though I have EnableViewState set to true, CheckBox1 is not retaining
    its value (false) on page reload.

    I have an OnLoad page sub that queries a SQL table for the member's record.

    I use Dim bolLoadedOnce As Boolean in the codebehind class for the page.

    Then I use:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArg s)
    Handles Me.Load

    If bolLoadedOnce = True Then

    Else
    fLoadMemberSett ings()
    bolLoadedOnce = True
    End If

    End Sub

    When I un-tick CheckBox1 it automatically fires a page reload which loads up
    CheckBox1 as True again. I want it to remember that I un-ticked it.

      Get rid of bolLoadedOnce. It 1) doesn't survive postbacks and 2) already
      provided by ASP.NET as IsPostBack property.

      Use IsPostBack.
