Handling ToolBar Event

EO.Web ToolBar supports both server and client side events.

Handling Client Side Event

By default EO.Web ToolBar only raises client side event. The following table lists all client events:

Event

Remark

ClientSideOnItemClick

Occurs when a tool bar item is clicked. The following code demonstrates how this event is used:

function on_item_click(toolBar, toolBarItem)
{
    window.alert("ToolBar item '" + 
        toolBarItem.getCommandName() + "' clicked.");
}

<eo:ToolBar ClientSideOnItemClick="on_item_click" ....>
    ....
</eo:ToolBar>

ClientSideBeforeSubMenuExpand

Use this property to modify the drop down menu before the sub menu is displayed. The following code demonstrates how this event is used:

function before_submenu_expand(toolBar, toolBarItem, subMenu)
{
    var menuItem = subMenu.getItemByIndex(0);
    menuItem.setText("New item text!");
}

<eo:ToolBar ClientSideBeforeSubMenuExpand="before_submenu_expand" ....>
    ....
</eo:ToolBar>

Handling Server Side Event

EO.Web ToolBar can raise server side ItemClick event when AutoPostBack is set to true. Handling this event is no different than handling any other server event.
