RadAutoCompleteBox works on localhost but not when published.

[John]

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.

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.

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.

I downloaded you files and created a new project.

When I run it

Error Message.

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?

Hi Team,

This sample is working in my system.

Thank You

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...

Hi Tomasz,

We are not aware of such known issue in the current version of the control. Would you please share the exact code connected with RadAutoCompleteBox that you are using so we could inspect it and be more helpful?

[Tomasz]

Your suport is already working on it because I've provided a sample solution which was admited to have a bug in this scenario :)

[Nessi]

Any update on this issue?

I have the same effect, getting the error about the IDoctionary when accessing the web service.

[Plamen]

Hi,

We are not aware of such issue in the latest version of the controls. You can refer to this online demo where the scenario is working correctly. If you still observe the issue please elaborate the exact code that should be used to replicate it at our side.

I am having the same issue using Telerik build: 2016.3.1027 (Dev)

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.

Can someone help?

[Plamen]

Hi,

I have tested a scenario once again with the sample page that was attached in the answer by Kalina on 18-Oct-2012 5:26:54 PM and it still worked correctly at my side.

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.
