pass dynamic variable to DataAdapter

[HugoParticipant]

Hello guys,

You can pass dynamic variable to DataAdapter depending on certain condition?

example:

var source = new $.jqx.dataAdapter({
     datatype: 'json',
     datafields:[{ name: 'field' }, { name: 'field' }],
     url: 'mypage.php',
     data: { mydata: ????? }, // <-- variable
     cache: false,
     async: false
});

$('$jqxGrid').jqxGrid({
   ...
   columns: [
      { 
          text: 'my',
          datafield: 'my',
          width: 200,
          columntype: 'dropdownlist',
          createeditor: function( row, cellvalue, editor ){
	     editor.jqxDropDownList({ source: [], displayMember: 'field', valueMember: 'field' });
          },
	  initeditor: function( row, cellvalue, editor, celltext ){
	     /*
                Loads the source based on cellvalue
             */
	     editor.jqxDropDownList({ source: source, displayMember: 'field', valueMember: 'field' });
          },
          .. etc
   ]
});

Hi Hugo,

You can define the dataAdapter’s formatData callback. It is called on each dataBind call.

var dataAdapter = new $.jqx.dataAdapter(source,
    {
        formatData: function (data) {
            $.extend(data, {
                featureClass: "P",
                style: "full",
                maxRows: 50
            });

            return data;
        }
    }
);
