ExtGridEventHandler

Scoped name

WSYEXTJS/ExtGridEventHandler

Purpose

This is the standard EventHandler, which you should use when you want a grid event in an Ext JS WebsydianExpress application.

When you comprise/include an EventHandler of this type on a PageGenerator, a button will be placed in the grid region of the page. The button will occur for each record in the grid.

Usage

The EventHandler inherits from ExtEventHandler and has the same basic functionality and settings, with two main exceptions:

• The function option WSYD Grid event is set to Yes, which means that the button will be placed in the grid region (one for each record).
• The wsyeventtype source code has the default value wsyextstandardgridevent, which provides the JavaScript support needed for the grid event.

Special considerations

As for all Websydian grid events, the values in the webinput variable will be populated by the WsyGrid values of the record the button is shown in.
