data store as input.

eg.

var store = new ObjectStore(

{

"objectStore": new Memory(

{

"data": data.caseHistories.items

})

});

grid.setStore(store);

Formatting

The "structure" property which defines columns, has a field called formatter that is

supplied as a function that takes the data value as a parameter.

Before going further, let us re-iterate where the formatter function is defined. It is defined within a

structure column definition and hence it has peer fields which include "field". The "field" property

names the field within the array of objects (data) that is used for sourcing the value for the cell. It is

the value of the data object's property contained in the "field" attribute that is passed to the

formatter function.

As an alternative to supplying a single "field" name, we can supply an array of field names. In this

case, the parameter passed to the formatter function will be an array of values.

Finally, we can define the field name as the magic value "_item" and in this case the complete

object corresponding to the row will be passed to the formatter function.

The function must return an HTML string that will be displayed in the cell.

{

field: "Failure",

name: "Status",

width: "100px",

formatter: function(didFail)

{

if (didFail == false)

{

return "<img src='images/ok.png' />";

}

return "<img src='images/fail.png' />";

}

As an alternative to returning HTML string, we can also return a Dijit Widget:
