Using loading items message template in WebDropDown

When using the load-on-demand feature, WebDropDown™ allows you to show a customized loading message by setting the LoadingItemsMessageText property. If this property is set, a message will appear notifying the end-user that loading is in progress during AJAX postback. However you can also apply a loading items message template to the loading message using the WebDropDown control’s LoadingItemsMessageTemplate property.

To use loading items message template in WebDropDown:

  • From the Visual Studio™ Toolbox, drag and drop a ScriptManager component and a WebDropDown control onto the form.

  • In the source code, include the following code between the WebDropDown tags to show the loading message using the LoadingItemsMessageTemplate tags.

In HTML :

<LoadingItemsMessageTemplate>
                <div id="loadTemplate" style="background-color : Aqua">
                    <span id="actualMsg">Loading, please wait…</span>
                </div>
</LoadingItemsMessageTemplate>

  • Save and run your application. When you scroll down the scrollbar of the drop-down container , you will observe that the loading items message template is applied to the loading message.
