Question

On my webpage I am loading multiple instances of a usercontrol, sometimes the usercontrol is laoded within itself. I need to save a bunch of properties for the round trip of a post back but i am confused on how to save those properties to ViewState and set them again to the repeater items within the usercontrol.

Can anyone help me in this situation, I have read the MSDN on Viewstate but I am not understanding it quite well for some reason

This is how I load the parent user controls (child controls are loaded the same way with the same user control)

Protected Sub Load_Controls(ByVal list As List(Of BSEvaluationGroup.category), ByVal gid As Integer, ByVal pid As Integer, ByVal fid As Integer)
    Dim item As BSEvaluationGroup.category
    For Each item In list
        Dim ctl As PerformanceEvaluationSubcontractorControl = CType(Page.LoadControl("PerformanceEvaluationSubcontractorControl.ascx"), PerformanceEvaluationSubcontractorControl)
        ctl.categoryid = item.catid
        ctl.categoryname = item.catname
        ctl.projectid = pid
        ctl.folderid = fid
        ctl.groupid = gid
        ctl.parentid = item.parid
        ctl.clist = item.categories
        ctl.plist = item.points
        ctl.parentpage = Me
        ctl.EnableViewState = "true"
        If (Not subcon Is Nothing AndAlso Not subcon.points Is Nothing) Then
            ctl.epnts = subcon.points
        End If
        AddHandler ctl.BubbleCalculate, AddressOf Me.PostRating

        Select Case gid
            Case 1
                Me.officephld.Controls.Add(ctl)
                Dim ohrule As HtmlGenericControl = New HtmlGenericControl("hr")
                ohrule.Style.Add("width", "100%")
                ohrule.Style.Add("background-color", "Silver")
                ohrule.Style.Add("size", "1px")
                ohrule.Style.Add("border-width", "0")
                ohrule.Style.Add("padding-top", "1px")
                ohrule.Style.Add("float", "left")
                Me.officephld.Controls.Add(ohrule)
            Case 2
                Me.sitephld.Controls.Add(ctl)
                Dim shrule As HtmlGenericControl = New HtmlGenericControl("hr")
                shrule.Style.Add("width", "100%")
                shrule.Style.Add("background-color", "Silver")
                shrule.Style.Add("size", "1px")
                shrule.Style.Add("border-width", "0")
                shrule.Style.Add("padding-top", "1px")
                shrule.Style.Add("float", "left")
                Me.sitephld.Controls.Add(shrule)
        End Select
    Next
End Sub

It was a control ID issue, I removed it instead of adding an ID
