I am still in a telerik evaluation phase and working with an evaluation copy.
I am very new to web-application development, so forgive me if my question is dump.

From a record-selection form I want to allow the user to call multiple update forms.
This works without problems.
But if I close one or all of the individual update forms and than call up additionally update-forms, all the previously created forms are popping up again. What have I forgotten?

To demonstrate my problem see the following example.
Just press the [New RadWindow] button multiple times.
Then close all created windows by pressing [Close Window].
When you then press the [New RadWindow] all the previously created forms and a new one are showing.
How can I supress the showing of previusly closed forms?

Default.aspx

Also, user can edit contact information, and also in the photo, i do the edit in another page opened in a Radwindow....all is fine and all the data is updated in database even the image, i call the grid rebind via an ajax request and also the grud is refreshed...BUT, neither the image control in the edit window page and the cloumn in the radgrid is refreshed until i call the page again!!!!

i debug the code, and the ImageURL is rewritten but the ShowContactPhoto.ashx is not called again until i call the whole page which holds the grid again!!!

i tried to send a random number within the url so not called from the cash,,, but still not called!!!

how can i acheive this, i need to show the updated image in the edit window and the grid without the need  to call the page again!!!

any help will be geat...
thanks

Installed Telerik components: RadControls for ASP.NET AJAX Q2 2011 SP1

Text:
I created two projects, a WFC Service (name: PartialProjectServiceAjaxTest) and a Web Application (name: PartialProjectASPXAjaxTest).

The service  in his basic form, was a copy of the code on http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/linqdatasource/defaultcs.aspx.

The important changes in the code:

-        Add a list <person> and read this list with LINQ

The aspx in his basic form, was a copy of http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/autocompleteclientside/defaultcs.aspx

The important changes in the code:
- add RadScriptManager1
- <WebServiceSettings Path="http://localhost:54266/Service1.svc" Method="LoadData"  /></telerik:RadComboBox>  (54266 is the used port)

When i deploy the projects, it’s possible to see the UI, but when i will show up the results of the service, in the ComboBox, i will get an error message:
‘The server method ’LoadData’ failed’

This message is parsed right after clicking the textbox in the UI.

Testing:
- First i created a console app to test the service. Because i could load the data, the service doesn’t generate the error;
- Then i commented the code that filter the results. I need data anyway and will filter them in a later stage. I got the same error;

-Debugging both of the projects doesn’t give any explanation;

My question is: Why isn’t it possible for me to load the LoadData method in my Web app in case of a good functioning service?

The most inportant code:
