I have a project with RadAutoCompleteBox and every thing works fine on my localhost, but when I upload it the page doesn't crash but the drop down doesn't appear at all but yet it works fine on my computer.

I have the RadAutoCompleteBox binded to a web service.

When I go to the web service page online I get the following error. 

Cannot serialize member Telerik.Web.UI.AutoCompleteBoxData.Context of type System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]], because it implements IDictionary.


Here is my code in the web service.

                            }
 
                            dropDownData.Items = result.ToArray();
                            return dropDownData;

When I have the following.

public AutoCompleteBoxData GetStaffNames(object context)

 

It works fine on the aspx page and the drop down appears but when I go to the web service page it shows
The type Telerik.Web.UI.RadAutoCompleteContext is not supported because it implements IDictionary. 
But it works.

When I make it. 
public static AutoCompleteBoxData GetStaffNames(object context)

The web service is fixed and no errors but when I run the axpx page no drop down appears.

This problem is doing my head in, any help would be gladly appreciated.
 
Thanks

After 5 days of this problem doing my head in and have tried everything I went to the telerik tab in visual studio and went to  
RadControls for asp.net AJAX and went to the upgrade wizard because I was bored.

Published the site and guess what it worked on webhost even thou if I go to the web service directly it doesn't work and says about Idictionary.

The type Telerik.Web.UI.RadAutoCompleteContext is not supported because it implements IDictionary.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NotSupportedException: The type Telerik.Web.UI.RadAutoCompleteContext is not supported because it implements IDictionary.

This must be a major problem with this control connected to a webservice.

Hello John,

The issue that you describe is quite strange.
Populating the RadAutoCompleteBox with data via WebService works properly on our online demo here.

I simplified your web service implementation and prepared a very basic sample – could you please download it and test it on your side?

Maybe there is something specific in your project (or implementation) that causes the issue?
I believe that a working sample on your side will help you to find it.

Hello John,

The sample web site that I have provided you works properly on my side - please take a look at this demonstration video.
Did you change the sample web site before running it?
Where did you receive the error - on your development machine or on the server where you publish the website?

I have the same issue.
On my dev machine it works fine but after publishing to my hosting the control doesn't work.
I'm using SQL Data Source, I've EF and OpenAccess also with the same results...

No errors, no nothing...

Without knowing as much as Telerik about their control I can only surmise from what one poster is saying is that when you try and attach to your webservice it, auto.., can't use the data because its implements a dictionary object.

My first guess is that your webservice is not providing you the two pieces of data to create a dictionary object which is what it needs. If you look at the auto box you have to give it a value and text field. If your WS only returns one it will fail.

Create a class that takes two pieces of data. One a integer for a counter and the other a string for your data. When you grab the data JSON or XML add it to your class. As you loop the WS data increment a counter. Now you have a object, you can attach to your autocomplete box with both pieces of information that it needs. Make sure to set the text/value fields on the autobox to whatever you called them in your class.

Don't know if that works without testing it but I see no reason why it wouldn't.
