WebDropDown Web Service Client Side

Lokesh Manapure posted over 10 years ago

Hi Everyone

just been playing around but cant seem to find any way to hook the WebDropDown to a web service on the client side like the ajaxtoolkit autocompleteextender see link and example below:

http://www.asp.net/ajaxlibrary/ajaxcontroltoolkitsamplesite/autocomplete/autocomplete.aspx

Example:

<AjaxToolKit:AutoCompleteExtender ServiceMethod="ExampleMethod" ServicePath="~/AutoComplete.asmx" MinimumPrefixLength="1"
CompletionInterval="10" TargetControlID="txtbxExample" ID="AutoCompleteExtender1" runat="server">
</AjaxToolKit:AutoCompleteExtender>

i would want the WebDropDown to populate after a number of characters had been entered unlike the example given by infragistics which binds on the server side see link below:

http://help.infragistics.com/Help/Doc/ASPNET/2011.1/CLR4.0/html/WebDropDown_Binding_WebDropDown_to_a_Web_Service.html

i would also want to group the items if possible

Example

any help would be appreciated

Thanks

Hello,

Thank you for your post.

As I understand you want to retrieve some data from a WebService and bind it on the client.

I have create you a sample in order to show you this approach, although my data is a static json. You will need to set EnableClientRendering to true and to perform some other changes, for more information see the code snippet below:

<ig:WebDropDown ID="WebDropDown1" runat="server" Width="200px" EnableClientRendering="true"

                DropDownContainerMaxHeight="200" EnableDropDownAsChild="false" CurrentValue=""

                EnableCustomValues="true" TextField="Data"

                ClientEvents-DataBinding="onDataBind" DisplayMode="DropDown">

            </ig:WebDropDown>

Also I am using jquery template to set the items as you desired.

................

function onDataBind(sender, eventArgs) {

            eventArgs.set_cancel(true);

            sender._pi.show(sender);

            var dataSource = data;

            sender.set_dataSource(dataSource);

            sender.set_template(MyTemplate);

            setTimeout(function () {

                sender.dataBind();

                sender._pi.hide(sender);

                sender.set_currentValue("");

            }, 500);

        }

    </script>

    <script id="MyTemplate" type="text/x-jquery-tmpl">

        {{if (Species == "Mamels") || (Species == "Dinosaurs") }}

            <li><i><b>${Species}</b></i></li>

        {{else}}

            <li>${Species}</li>

        {{/if}}

    </script>
