Autocomplete with parameter

[İsyazilim]

Hi, 
    i have a radcombobox for autocomplete.

 

    I use web service for populate combobox.
    I want to send variables to web service from any other item's value on form (textbox,dropdown etc.)
    Ajaxautocomplete extender, there is UseContextKey feature.

    For radcombobox is there any feature?

    Regards.

Hello Kurkcu,

Yes, you can use the Context object to send additional data to the web service as described in this demo (see the code in the Products.cs file).

Kind regards,

Hi,
     I can send additional data to the web service. But i want to send additional data from other items.
    <telerik:RadComboBox ID="RadComboBox3" runat="server" Width="250px" Height="150px">
                <WebServiceSettings Method="GetCompanyNames" Path="Products.asmx" />
  </telerik:RadComboBox>
    <asp:textbox id="txtAdditionalDataHolder" runat=server/>

    Context is radcombobox content, but i want to add data from textbox.

    Thanks.

Hi Kurkcu,

You can try collecting data from the other form fields in this way:

var additionalDataHolder = $get("txtAdditionalDataHolder").value;
Context["AdditionalDataHolder"] = additionalDataHolder;

The approach is straightforward: get the form field object and put its value in the Context object with an appropriate key. Later you can get this data from the Context object in the Web Service.

I hope this helps.

Sincerely yours,

or can you send me sample code. (Combo box,textbox,javascript)

Hello Kurkcu,

The most convenient place to do this is in the client-side ItemsRequesting event handler as described in this help article.

All the best,
