Passing data to context in RadAutoCompleteBox throws an error

How to pass additional data to context from RadAutoCompleteBox

This is on my markup, the retrieval of data is working but passing the data to context from the RadAutoCompleteBox has a problem.

<telerik:RadAutoCompleteBox

   ID="racbTest"

   runat="server"

   DataTextField="Text"

   AutoPostBack="False"

   TextSettings-SelectionMode="Single"

   OnClientItemsRequesting="TestRequesting"

   InputType="Text"

   AllowCustomEntry="True">

   <WebServiceSettings

       Path="../DataSources/DataLoader.asmx"

       Method="SearchTest">

   </WebServiceSettings>

</telerik:RadAutoCompleteBox>

 

<telerik:RadCodeBlock runat="server">

   <script>

      function TestRequesting(sender, args) {

         args.get_context()["Foo"] = "Bar";

      }

   </script>

</telerik:RadCodeBlock>


and this is the code in the web service

[WebMethod]
public AutoCompleteBoxData SearchTest(RadAutoCompleteContext context)
{
   string searchString = context.Text;
   string foo = context["Foo"].ToString();
}

the problem is in the WebMethod, the context["Foo"] throws an error that

The given key was not present in the dictionary.

Any help would be appreciated.. Thanks in advance.

Hi Virgilio,

The problem here is the name of the event - in RadAutoCompleteBox it's called OnClientRequesting. Since you are using the OnClientItemsRequesting name, the event it never triggered and the "Foo" key is not added to the dictionary.
