Problem using the same formview within a webusercontrol multiple times on a page

First I'm using VS 2005 with AJAX, and I have a created a SQL Server 2008 Database to track some of our computer componet hardware.

I've created "Web User Controls" for nearly all my objects, and have placed them inside my monitors page. I have a button for editing a monitor and adding a monitor. Both Buttons open a ModalPopupExtension UpdatePanel that contain my WebUserControl. The WebUserContrl has a modified FormView for Editing and Inserting records in the Monitors table. I'm using Session parameters to of "MonitorEdit" to allow the webusercontrol on Page load to set the FormView1.DefaultMode = FormViewMode.????

My problem is getting the FormViews to switch from a "ReadOnly", "Edit", and "Insert" modes. It seems that the webusercontrol is being set for both popups on the initial load, and I have no way of changing them on the fly. I've read some articles about making the FormView properties public, but I'm unsure how to do that, and if that would even help. Below is my code, and hope this makes sense. Thanks for any help.

Now Code behind on my Web Form:

Partial Class Test
Inherits System.Web.UI.Page

Protected Sub btnAddMonitor_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Session("MonitorEdit") = "Insert"
End Sub

Protected Sub btnEditMonitor_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Session("Monitor_ID") = "1"
Session("MonitorEdit") = "View"
End Sub

End Class

************************************************************
Now Code behind on my Web User Control:

Partial Class Controls_MonitorEdit
Inherits System.Web.UI.UserControl

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

If Session("MonitorEdit") = "" Or Session("MonitorEdit") = "Insert" Then
FormView1.DefaultMode = FormViewMode.Insert
ElseIf Session("MonitorEdit") = "View" Then
FormView1.DefaultMode = FormViewMode.ReadOnly
ElseIf Session("MonitorEdit") = "Edit" Then
FormView1.DefaultMode = FormViewMode.Edit
End If

End Sub
End Class

mr_nadger

in the webcontrol,
add another method to control the formview's mode (this is written on the fly but should give you the idea)

Public Sub switchMode()
Select Session("MonitorEdit")
Case "", "Insert"
FormView1.ChangeMode(FormViewMode.Insert)
Case "View"
FormView1.ChangeMode(FormViewMode.ReadOnly)
Case "Edit"
FormView1.ChangeMode(FormViewMode.Edit)
End Select
End Sub

Put the webcontrol inside an updatepanel set to trigger on the button being clicked, and this should get you what you want
(I prefer using a case statement here as it's easier to follow the logic, but If's just as valid)

mr_nadger

doh forgot to mention calling webcontrol.switchMode() from the button being pressed!

mr nadger,

Thanks for your help, but the webcontrol is not getting the new session variable that I am setting when I click on the button. Could this be that the modalpopup is redering before the button onclick is run, or does the popupmodal null the button onclick?

Mr Nadger,

Thanks for the help. I finally figured it out and you put me in the right direction. I ended up having to set the modalpopupextender to open on a third, hidden box, so that the button would run first, then I would call the ModalPopupExtender1 to open.

Session("MonitorEdit") = "Insert"
MonitorEdit1.switchMode()
upAddMonitor.Update()
ModalPopupExtender1.Show()
