Show an Alternate Name for FlexGrid's GroupRow Property

Background:

When using FlexGrid with grouping enabled, the property value gets displayed. However, sometimes there might be a need to change the default value. For example, if grouping is enabled based on country, then the full country name will be displayed.  Let’s say we would like to display the initials of the country or the first three letters instead.

The following code snippet can be used to show custom value for grouping:

var gd = new wijmo.collections.PropertyGroupDescription('country',  function(item, propName) {    
     return item[propName][0]; // return country's initial  
     //return item[propName].substring(0,3) ; // return first three letter
});
cv.groupDescriptions.push(gd);
