How to get the maximum number in a grid column

Hi,

I have a requirement to get the maximum number in a column. In EJ1 I did it as bellow and how do I do it in EJ2.

 

var gridObj = $("#FlatGrid").data("ejGrid");

var NewLineNo = ej.max(gridObj.model.dataSource, "LinNo").LinNo + 1;



Thank you and best regards,

Kalum

Hi Kalum,


Thanks for contacting Syncfusion support.


By using the EJ2 Datautil/ DataManager, you can get the maximum value of a particular field from the JSON data.


 

// get the sorted data using DataUtil

var sortedData = ej.data.DataUtil.sort(window.orderData, 'OrderID', ej.data.DataUtil.fnDescending);

// get the maximum value of OrderID

if (sortedData.length) {

  maxnumber1 = sortedData[0]['OrderID'];

  console.log(maxnumber1);

  document.getElementById('Grid').innerText = 'Max number is - ' + maxnumber1;

}

 

// get the sorted data using DataManager with take query as 1

var maxNubmerRecord = new ej.data.DataManager(window.orderData).executeLocal(

  new ej.data.Query().sortBy('OrderID', 'descending').take(1));

// get the maximum value of OrderID

if (maxNubmerRecord.length) {

  maxnumber2 = maxNubmerRecord[0]['OrderID'];

  console.log(maxnumber2);

}
