I am having multiple problems with the combo box control and event handling/population between Visual Studio 2010/Windows 7 and operation under Server 2008 site.

I am developing/supporting a web site under Visual Studio 2010 on Windows 7. All of my combo boxes are working fine. I have both cascading combo boxes that trigger javascript and combo boxes that utilize the SelectedIndexChanged. In all cases, these combo boxes operate just fine when testing them on my development machine.

But when I upload the pages/site up to a Server 2008 machine, the combo boxes/events do not fire correctly or they do not operate correctly. Cascading combo boxes show the "Loading..." text, but never populate. A combo box that is supposed to trigger a SelectedIndexChanged event triggers the event, but then the combo box resets back to the value before the user selected a new one.

How can all of this be happening? Why would a combo box would perfectly under Visual Studio/Windows 7 and not under Server 2008?

Can anybody offer an explanation?

Below is the code from one of the "SelectedIndexChanging" combo boxes.

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="LanguageSelector.ascx.vb" Inherits="UserControls_LanguageSelector" %>

<telerik:RadComboBox

ID="LanguageSelectorComboBox"

AutoPostBack="true"

EnableEmbeddedSkins="true"

Skin="Sitefinity"

runat="server"

Height="200px"

Width="215px"

ZIndex="9000"

>

</telerik:RadComboBox>

Protected Sub LanguageSelectorComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs) Handles LanguageSelectorComboBox.SelectedIndexChanged

If Page.IsPostBack Then

Dim KeyVal As String = e.Value

Dim languageId As Integer = Convert.ToInt32(KeyVal)

Dim conn1 As New SqlConnection(Convert.ToString(Application("SiteDBConnect")))

Try

conn1.Open()

Catch ex As Exception

Throw New ApplicationException("Error in connection=" & ex.Message & ". The requested list cannot be created.")

Finally

End Try

Dim iRtn As Integer = 0

Dim Languages_Data As New Languages_DDC()

Dim Languages_Cmds As New Languages_DUC()

Dim Currencies_Data As Currencies_DDC = New Currencies_DDC

Dim Currencies_Cmds As Currencies_DUC = New Currencies_DUC

Dim TransTextSort_Data As TransTextSort_DDC = New TransTextSort_DDC

Dim TransTextSort_Cmds As TransTextSort_DUC = New TransTextSort_DUC

Dim TransTextSort_Arry As ArrayList = New ArrayList

Dim iUSDKey As Integer = 1

Dim iForgnKey As Integer = 0

Dim currencyId As Integer = Session("UserCurrencyKey")

Dim iDebug As Int32 = -1

Languages_Data.LanguageId = languageId

iRtn = Languages_Cmds.GetSpecific(conn1, Languages_Data, iDebug, "HON")

If iRtn = -1 Then

If bSetSessionValue Then

Session("UserLanguageKey") = Languages_Data.LanguageId

Session("UserLanguageCulture") = Languages_Data.LanguageTransCulture

Session("UserLanguageName") = Languages_Data.LanguageEnglishName

Session("UserChangedLanguage") = "Yes"

Session("UserLanguageNum") = GetNewLangKeyStringValue(Languages_Data.LanguageId)

' Now we need to change the names of the session currency info so it is in the newly selected language

Dim sLangName As String = GetNewLangKeyStringValue(Session("UserLanguageKey"))

Dim sFieldToPopulate As String = "TextSortLang" & sLangName

iRtn = TransTextSort_Cmds.GetAllByTextSort_Currency(conn1, TransTextSort_Arry, currencyId, -1, "HON Currency Change")

For Each TransTextSort_Data In TransTextSort_Arry

'Session("USDLanguageName") = "United States Dollar"

'Session("NativeCurrencyLanguageName") = "United States Dollar"

Session("NativeCurrencyLanguageName") = TransTextSort_Cmds.GetField(TransTextSort_Data, sFieldToPopulate)

' There can only be one record in this array, so force an exit after processing the first record

' to protect us from something squirrely happening

Exit For

Next

' Now get the native language name for the USD, unless we already have it

If currencyId = 1 Then

Session("USDLanguageName") = Session("NativeCurrencyLanguageName")

Else

TransTextSort_Arry = New ArrayList

iRtn = TransTextSort_Cmds.GetAllByTextSort_Currency(conn1, TransTextSort_Arry, 1, -1, "HON Currency Change")

For Each TransTextSort_Data In TransTextSort_Arry

Session("USDLanguageName") = TransTextSort_Cmds.GetField(TransTextSort_Data, sFieldToPopulate)

' There can only be one record in this array, so force an exit after processing the first record

' to protect us from something squirrely happening

Exit For

Next

End If

If bReloadPage Then

Response.Redirect(HttpContext.Current.Request.RawUrl, True)

End If

conn1.Close()

conn1 = Nothing

End If

End Sub

This is just one example. I have more. If you want to see the results on the server 2008 system, navigate to http:://www.homesonlinenetwork.com and try changing the language selected in the combo box in the far upper right-hand corner. This same combo box works perfectly under Visual Studio 2010/Windows7.

Any thoughts/help would be greatly appreciated! I am stumped!

Thanks in advance!

Copying MS word content into editor

Hi,

In the tools.xml we have set restrictions such that the user is not able to change the forecolor or backcolor or table tags etc.
So many of the buttons are hidden from the user.

But I see that the user is able to copy any content from MS word into the editor and It works.It does not filter the content based on the restrictions we have set,

How can we restrict the content which i being copied into the editor.

Issues with Mobi Redirect and RadRotator

Greetings,

We are having some kind of compatability issues with 51degrees.Mobi redirects and RadRotator. We can not seem to use them on the same page or within the same Web.config.

There is a similar thread here: http://www.telerik.com/community/forums/aspnet-ajax/combobox/combobox-on-the-ipad-iphone.aspx#1707186

Basically, if we try to do a Mobi redirect on our home page which uses a RadRotator, the rotator ends up showing all of its panels on the page. We are opening a ticket with 51degrees as well, and we are waiting to see which of you will be more responsive to the issue. We really like using both Mobi and Telerik... it would be a shame if we have to choose between the two. I can provide contact information for 51degrees if necessary.

Please advise. Thank you!

Matt

WebResource and ScriptResource

I have a Windows Server 2008 with IIS 7. I've been using the app pool set to classic. I'm getting ton of the errors listed below and my frustration level is high now. When I look at it under Visual Studio or browse to it locally through IIS it works find. When I hit it externally, I can't get far and get a ton of the errors below. The site is on to web servers that have a load balancer. The site is 3.5 framework. Any ideas of how to handle this? Everything I read, says to just make sure you have the "handler" and "httphandler" taken care of.

Hi,

I'm looking at this example:

The question is how do I go about having a default value for the combo box ...
In the example above how would I set "Brazil" as the default value for the combo box ?
