Hi...

I'm experiencing a problem with the new AJAX Beta 2. When I try and put the UpdateProgess on a simple page, I get the below

Please can you help, this is driving me nuts... Wink

Thanks,

Clint,

Did you try to add the assemby reference to the web.config file? You don't need to register it in the page, and you don't need it in the BIN folder.
Also, it seems that your copy of the assembly is still Beta 1, have you uninstalled Beta 1 and, then, reinstalled Beta 2? That will install the correct assembly in the GAC.

Cheers,

Juan

Hi Juan, thanks for your help.

I've uninstalled the Beta 2 and reinstalled a fresh copy from the internet, and I've also deleted the files in the BIN directory and the reference in the .aspx page.
In addition, I've replaced my web.config with the one that is created from a new web project including AJAX (I've included it below) But I am still getting this error.

Server Error in '/Auction' Application.

Hi...

I've managed to fix it thanks ...

I tried creating a new project and copying the files across to it, and it worked!? Very Strange!?

Any Idea why this would be, even after I copied the entire now working project files back to the original folder that wasn't working, it still did not work??

Thanks for your help,
Clint

I don't know if this helps any or not, but I was originally getting the same error and this is how i resolved it:

*I should first mention I had Beta1 and the ValueAdd CTP implemented prior to Beta2. (I had implemented them simply by copying the Microsoft.Web.Extensions.dll and Microsoft.Web.Preview.dll to the app's Bin folder):

To implement Beta2 I followed the doc instructions (web.config modification), and deleted the 2 dll's from the Bin folder (and removed the web.config references to the ValueAdd piece).

That's when I started getting the same error you were.

UNTIL I restarted IIS. I'm guessing it (or ASP.NET) had the old dll's cached somewhere since I originally had them in the bin folder??

Hope it helps-

Kenneth

The assemblies are in the GAC, cached, etc. Restarting IIS as suggested below worked for me too.

I have created a dataset. Each method of the tableadapter shows the right data when I preview it at design time.
However, when I load the page I get the value in both dropdownlists: [method error 500]

If I step throught the code, the webmethod is not hit even though I put a breakpoint on it (or is that normal?)

Here's my code:

.ASPX

<asp:DropDownList ID="ddlCountry1" runat="server">
</asp:DropDownList>
<asp:DropDownList ID="ddlLocalCity" runat="server">
</asp:DropDownList>

<cc1:CascadingDropDown ID="CascadingDropDown1"
runat="server"
TargetControlID="ddlCountry1"
Category="CountryName"
prompttext="Select country"
ServicePath="LocalCities.asmx"
ServiceMethod="GetCountries">
</cc1:CascadingDropDown>
<cc1:CascadingDropDown ID="CascadingDropDown2"
runat="server"
TargetControlID="ddlLocalCity"
Category="CityName"
prompttext="Select city"
ServicePath="LocalCities.asmx"
ServiceMethod="GetCitiesForCountry"
LoadingText="Loading...">
</cc1:CascadingDropDown>

Local.vb

<WebMethod()> _
Public Function GetCountries(ByVal knownCategoryValues As String, ByVal category As String) As CascadingDropDownNameValue()
Dim countryAdapter As CountryMainCitiesTableAdapters.CountriesTableAdapter = New CountryMainCitiesTableAdapters.CountriesTableAdapter
Dim countries As CountryMainCities.tblCountriesDataTable = countryAdapter.GetData
Dim values As New List(Of CascadingDropDownNameValue)
For Each dr As DataRow In countries
Dim CountryName As String = CType(dr("CountryName"), String)
Dim countryId As Integer = CType(dr("CountryID"), Integer)
values.Add(New CascadingDropDownNameValue(CountryName, countryId.ToString))
Next
Return values.ToArray
End Function

<WebMethod()> _
Public Function GetCitiesForCountry(ByVal knownCategoryValues As String, ByVal category As String) As CascadingDropDownNameValue()
Dim kv As StringDictionary = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues)
Dim countryId As Integer
If (Not kv.ContainsKey("CountryID") _
OrElse Not Int32.TryParse(kv("CountryID"), countryId)) Then
Return Nothing
End If
Dim cityAdapter As New DataTable

Dim adapter As CountryMainCitiesTableAdapters.CountryMainCitiesTableAdapter = New CountryMainCitiesTableAdapters.CountryMainCitiesTableAdapter
Dim cityTable As CountryMainCities.tblCountryMainCitiesDataTable = adapter.GetDataByCountryID(countryId)
Dim values As New List(Of CascadingDropDownNameValue)
For Each dr As DataRow In cityTable
values.Add(New CascadingDropDownNameValue(CType(dr("CityName"), String), dr("CityID").ToString))
Next
Return values.ToArray
End Function

Try to follow up the following suggestions to fix the famous Method Error 500 for reference.
1.Try to read this thread -http://forums.asp.net/1476672/ShowThread.aspx#1476672
2.Try to write a web method in behind code to call web service as the following
???Country:<asp:DropDownList ID="ddlCountry" runat="server">
???</asp:DropDownList>
???<AjaxControls:CascadingDropDown ID="CascadingDropDown1" runat="server" TargetControlID="ddlCountry" Category="Country" ????LoadingText="Loading....." ServiceMethod="GetCountries" BehaviorID="CascadingDropDown1" PromptText="- select country -">
???</AjaxControls:CascadingDropDown
???[WebMethod]
???[ScriptMethod]
???public CascadingDropDownNameValue[] GetCountries()
???{
???????WebService ws = new WebService();
???????return ws.GetCountries();
???}
Wish the above can help you.

The other thread did not help me a lot. But I changed some code, however I still receive the error [method 500]

and if I add the attribute
ServicePath="default.aspx.vb" to CascadingDropDown2 I receive the error [method 404]

The code-behind method GetCitiesForCountry is never hit...
