PageIndex
A zero-based index of the clicked page.Brick
A visual brick object that is related to the clicked report control.Handled
Specifies whether default event handling is required.DefaultHandler
A function that runs when the Handled field is set to false (the default value). You can call this function within your event handler and set the Handled field to true to prevent the function from being called twice.GetBrickText
Returns the text displayed in the clicked element (report brick).GetBrickValue
Returns additional information on the brick.
For more information on report bricks, review the following help topic: Bricks.
The following code obtains the clicked element’s text:

onPreviewClick: function(s, e) {
e.Brick && alert(e.GetBrickText())
}
}
