Dashboard Toolbar Click Event

Trying to capture the Toolbar Click event within a customization for a dashboard. Using the wizard generates the event related to the MainController, however, there is no response from the following code except when entering Customization mode. How is the toolbar click event captured for a dashboard?

Correction: A response is only generated for the highlighted clicks. Why are the other button clicks not captured?

private void MainController_BeforeToolClick(object sender, Ice.Lib.Framework.BeforeToolClickEventArgs args)
	switch (args.Tool.Key)
		case "PrintTool":
			args.Handled = true;

We use

private void baseToolbarsManager_ToolClick(object sender, ToolClickEventArgs args)

with the event handler set up manually rather than by wizard. But this is in deployed dashboards - trying to customize Tracker views in non-deployed ones has proved too troublesome (just in case that’s what you’re doing).

Thanks for the help, Daryl!
