On Authentication Timeout - Save Web Form Contents

I was working on a project recently where I had to figure out how to persist user data in a web form after their Forms Authentication session as expired.

So I was thinking of ways to do this as I searched the know all Google. Walla!  Someone's already had to do this, why invent the wheel.  Found a post by Peter Ravnholt, on the MSDN site. http://code.msdn.microsoft.com/formsaver 

He Implements the HttpModule and handles saving the form state on FormAuthentication events. Really neat idea.  I tried is code, now keep in mind I'm doing this for Visual Basic, so I manually converted it all, but I couldn't get it work. Maybe I was converting something wrong.  I was getting "The state information is invalid for this page and might be corrupted."

Well RichardDeeming in the discussions for this post had an updated version that worked a little better then the original. http://code.msdn.microsoft.com/formsaver/Thread/View.aspx?ThreadId=88  Thanks to his code, I converted it to VB.Net and walla!  My pages now handle web content.

I'll post the converted VB version below. 

Thanks Richard and Peter if you ever find your names on here via Google :p

This is my VB version o the FormSaverHttpModule with Richard's changes.  I've modified it a bit since but this works.

IIS7 Windows7/Server2008 ApplicationPoolIdentity Security Change from Network Service


Yeah this one got me.. http://learn.iis.net/page.aspx/624/application-pool-identities/

The change microsoft made to have AppPool now run as “ApplicationPoolIdentity” instead of Network service.

So if you normally give Network Service rights needed to your webapp, you now have to stop doing that and change it to

IIS AppPool\DefaultAppPool



End of that.





  1. Open Windows Explorer
  2. Select a file or directory.
  3. Right click the file and select "Properties"
  4. Select the "Security" tab
  5. Click the "Edit" and then "Add" button
  6. Click the "Locations" button and make sure you select your machine.
  7. Enter "IIS AppPool\DefaultAppPool" in the "Enter the object names to select:" text box.
  8. Click the "Check Names" button and click "OK".

By doing this the file or directory you selected will now also allow the "DefaultAppPool" identity access.

Optimizing Pages that use Telerik Controls. Mainly RadGrid


I was watching a webcast on Telerik TV, it’s called Optimizing RadGrid for ASP.NET Ajax.  There is a lot of useful information there. I summarized a bunch of it.

On my test page I…

  • Added Browserfile...
    • Compressing ViewState for RadTelerik controls  (Dropped viewstate considerably from sample page, 50,776 bytes to 5,428 bytes)
  • Added RadCompression for AJAX Calls to drop traffic size on ajax post-backs (Not handled by IIS compression)
  • Reduce Request using StyleManager and RadScriptManager
    • Added RadStyleSheetManager to MasterPage (Combines all CSS sheets into one download to limit requests)
    • Switched to RadScriptManager on Masterpage instead of ScriptManage
      • Request dropped from 71 to 47


Summarized Tips

  • Bind Grid Data on PreInit event, this will keep data from going to the ViewState and cut down on page size
  • If the Grid is ReadOnly and no editing takes place, then turn off viewstate for the Grid. EnableViewState="False"
    • Features that will NOT work when viewstate is off
      • Custom Edit Forms (User Control or Form Template)
      • Filtering
      • Grouping
      • Using Cached Data and Paging Together
    • Features that WILL work when view state is off
      • Indexes of Selected Items
      • Indexes of Edited Items
      • Group-by Expressions and Settings (but not the expanded state of grouped items)
      • Sort Expressions
      • Style Properties (But not if applied to a single cell or row in ItemDataBound event)
      • Column Order and other column properties
      • All settings concerning hierarchy structure (but not the expanded state of the items)
  • Optimized Column Editors on Grid
    • Used Shared Data Picker for Date columns in your grid
      • This requires a hidden data picker on page, and template column with textbox that uses js to talk to the datepicker with client-api (See Example Here)
    • Use Template column for comboxes and use Load-On-Demand
  • Ajaxify the Grid
    • Compresses Ajax calls which IIS misses, use RadCompression to drop traffic size
    • Use StyleManager and ScriptManager to bundle all css and scripts into one call each to server
  • More Tips Here
  • Other Ways to Optimize
    • Client-side Binding
    • Custom Paging
    • Virtual Scrolling
    • Caching Data server-side
    • Hierarchy Load modes
    • Group load modes
    • Filtering
    • .NET 3.5 + Linq
    • Upgrade from IE6


Other Controls

  • Other Controls
    • Use Shared Data Picker
    • Use RadInputManager if you want Validated or Stylized instead of using the the RadNumeric or RadTextbox controls
    • Use Load-On-Demand RadComboboxes
    • On RadMultiPage set RenderSelectedPageOnly = True
    • Hide Grid's with Visible="False" not with surrounding Div's set to display none.
      • Hiding the Grid itself, it doesn't render or get bound, grid will get data when visible is set to true again.
  • Add App_Browsers folder with a file that has.. (This one is HUGE, dropped my page significantly)
    • Create a file and add
    • <browsers>
          <browser refID="Default">
                  <!--<adapter controlType="System.Web.UI.Page" adapterType="Telerik.Web.UI.RadHiddenFieldPageStateCompression" />-->
                  <adapter controlType="System.Web.UI.Page" adapterType="Telerik.Web.UI.RadSessionPageStateCompression" />

.Net Resetting Scroll Position When MaintainScrollPositionOnPostBack = True

Had a friend have an issue where he had select buttons on a gridview and on selected changed event he would update control at the top of his page.  However, he had MaintainScrollPositionOnPostBack set to True, so of course the browser would reload and scroll down to where he had clicked the Select button.

Found this article how to override the MaintainScrollPosition so it would go to the top of the page.  Works like a charm.


On postback, the ASP.NET page adds a call to the client-side function WebForm_RestoreScrollPosition(), which returns the browser's scroll position to the X and Y coordinates specified by the __SCROLLPOSITIONX and __SCROLLPOSITIONY form fields (which were assigned the browser's scroll position before the postback ensued). Consequently, the browser's scroll position is maintained across postbacks. The diagram below illustrates this interaction graphically.

In order to reset the scroll position, we need to add the above JavaScript to the rendered page's output and then call it before the call to WebForm_RestoreScrollPosition(). The following code adds a function (ResetScrollPosition) to the outputted markup and then injects a line of script that invokes this function. The server-side code uses the RegisterClientScriptBlock method to register the ResetScrollPosition function, which adds the function to the top of the form. As noted earlier, RegisterStartupScript adds a call to ResetScrollPosition at the bottom of the page.

Private Sub ResetScrollPosition()
If Not ClientScript.IsClientScriptBlockRegistered(Me.GetType(), "CreateResetScrollPosition") Then
'Create the ResetScrollPosition() function
ClientScript.RegisterClientScriptBlock(Me.GetType(), "CreateResetScrollPosition", _
"function ResetScrollPosition() {" & vbCrLf & _
" var scrollX = document.getElementById('__SCROLLPOSITIONX');" & vbCrLf & _
" var scrollY = document.getElementById('__SCROLLPOSITIONY');" & vbCrLf & _
" if (scrollX && scrollY) {" & vbCrLf & _
" scrollX.value = 0;" & vbCrLf & _
" scrollY.value = 0;" & vbCrLf & _
" }" & vbCrLf & _
"}", True)
'Add the call to the ResetScrollPosition() function
ClientScript.RegisterStartupScript(Me.GetType(), "CallResetScrollPosition", "ResetScrollPosition();", True)
End If
End Sub

To reset scroll position on postback, simply call the server-side ResetScrollPosition() method from the appropriate event handler (be it the Click event handler of a Button, the PageIndexChanged event of the GridView, or some other event).

HTTP Error 404.17 Not Found – Using WCF .SVC Service

So you’re getting IIS error’s when trying to run a .svc file that’s coded to use WCF or Windows Communication Foundation.

HTTP Error 404.17 - Not Found

The requested content appears to be script and will not be served by the static file handler.

or maybe..

HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

Took me awhile to realize I need to setup/configure IIS and WCF properly.  Here are the steps from MS, I went through and realized I had missed one component (IIS6 Scripting tools, who would have thought), which I probably didn’t need, but the big ones that I didn’t have WCF Http Activation installed.  After that, I registered WCF..

"%WINDIR%\Microsoft.Net\Framework\v3.5\WFServicesReg.exe" /c

and then I was golden, but there might be other things you are lacking or missing. So go through all the steps.

One-Time Set Up Procedure for the Windows Communication Foundation Samples

Set the DefaultButton inside a LoginView Control in a MasterPage

Ok if you google this you’ll get some solutions that say set the DefaultButton to ParentControlID$ButtonID

However, this didn’t work for me. I kept getting the same error no matter what I tried.

The DefaultButton of '<PanelID>' must be the ID of a control of type IButtonControl.

So I tried another approach that worked great.

On page load I found the Panel Control and found the button control and set the default button programmatically.

<asp:LoginView ID="LoginView1" runat="server">
        <asp:Panel ID="pnlLogin" runat="server">
            <telerik:RadTextBox ID="tbUsername" runat="server" EmptyMessage="Username" />&nbsp;
            <telerik:RadTextBox ID="tbPassword" runat="server" EmptyMessage="Password" TextMode="Password" />&nbsp;
            <div id="SignIn" style="position: relative; z-index: 1; float: right; bottom: 21px;">
                 <asp:LinkButton ID="lbSignIn" runat="server" Font-Bold="true" Font-Size="Small" Text="SIGN IN" OnClick="lbSignIn_Click" />
            <div id="divLoginLinks" style="position:relative; clear:both">
                <span class="GrayFooterFont"><asp:HyperLink ID="hlRegister" runat="server" Text="Register" NavigateUrl="~/Registration.aspx" /> | <asp:HyperLink ID="hlForgot" runat="server" Text="Forgot Password" NavigateUrl="~/ForgotPassword.aspx" /></span>
        <small><asp:Label ID="lblLoggedInUsername" runat="server" /> | <asp:LinkButton ID="lbSignOut" runat="server" Text="SIGN OUT" OnClick="lbSignOut_Click" /></small>
        <asp:LinkButton ID="lbSignIn" runat="server" Font-Bold="true" Font-Size="Small" Text="SIGN IN" OnClick="lbSignIn_Click" CssClass="hidden" />

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    'If User is not logged in do this        
    Dim pnlLogin As Panel
    Dim lbSignIn As LinkButton
    pnlLogin = CType(LoginView1.Controls(0).FindControl("pnlLogin"), Panel)
    lbSignIn = CType(LoginView1.Controls(0).FindControl("lbSignIn"), LinkButton)
    pnlLogin.DefaultButton = lbSignIn.ID
    pnlLogin = Nothing
    lbSignIn = Nothing
End Sub

I’m sure I could have just hardcoded the lblSignIn ID to the pnlLogin, but no idea why I didn’t.

Simple Grid Boolean Value Yes/No from DB or CustomYes/CustomNo

I'm just putting this up here so I have it somewhere when I forget.

Sometimes I pull data from my database from a Bit column or boolean column and want to display more then True/False.

With a simple statement you can make it say anything you want.

<asp:TemplateField HeaderText="Is Active">
<asp:Label id="lblActive" runat="server" Text='<%#IIf(Boolean.Parse(Eval("Active").ToString()), "Yes", "No")%>' />

Using Resource File to Populate DropDownList

I had desire to populate a DropDownList with values from a resource file. Using the resource name as the ddl value and the resource value as ddl text.  There’s other reasons I need to do this but I’m simplifying it here.

The resource file name is: “BatchFields_ADMRACClaim
The DropDownList is called “ddlFeilds”

So first I get the resource file object and then I do a GetType() to initialize it. If anyone has any other suggestions for this, please let me know. Without the GetType() line or pulling out a value first, the GetResourceSet later is Nothing.

Dim BatchFileResource As ResourceManager
BatchFileResource = Resources.BatchFields_ADMRACClaim.ResourceManager()
Dim Value As String = BatchFileResource.GetType.Assembly.FullName

Then once I have the resource file in the “BatchFileResource” object, I can then loop through the items and dump them into a DropDownList.

Dim BatchResourceSet As ResourceSet = BatchFileResource.GetResourceSet(System.Globalization.CultureInfo.CurrentCulture, True, False)
Dim BatchEnumerator As IDictionaryEnumerator = BatchResourceSet.GetEnumerator()
While BatchEnumerator.MoveNext
Dim ddlItem As New ListItem(BatchEnumerator.Value, BatchEnumerator.Key)
End While

And that’s it. I’ve found other samples on the web but I’ve combined the best of both worlds here.
