One of WebCombo's most powerful features is the ability to accommodate a broad range of scenarios through its extendable capability using client-side events. In this section, we will see how we can attach a client-side event handler to the event using the Client-side Event Editor.

Assuming that you already have the combo bound to a data source and there is data to be displayed, the steps needed are as following:

1. Switch to design view of the page and right-click on the combo, then select Properties.
2. In the Properties tab, expand LayoutSettings - ClientSideEvents nodes.
   
   
   
   
3. Find the OnAfterItemSelected event and click the drop down arrow. In the drop down list you will see an item Add New Handler - WebCombo1_OnAfterItemSelected_1(controlId) and/or other event handler names if the page has already contained other client-side event handlers.
4. Click on the Add New Handler... item. The page will then automatically switch to HTML view and the event handler will be automatically added.
