Enquiry about adding a checkbox to the dialog box

I want to add a checkbox to the gantt chart dialog box, which I can read in the controller to check the user ticks it or not when updating, inserting or deleting a record in the dialog box. So far everything is in the default setting, and I used the e-data-manager and the controller behind to bind the data to my database:


The BatchUrl in the controller is:

public class CRUD where T : class
public List AddedObject { get; set; }
public List ChangedObject { get; set; }
public List DeletedObject { get; set; }
public object key { get; set; }
public string action { get; set; }
public T Value { get; set; }

public IActionResult BatchUrl([FromBody] CRUD batchmodel)
//how can i get the checkbox value here? I need it because it decides how I upload the data to the database

if (batchmodel.ChangedObject != null)
//update to database

Hi Desmond,

Greetings from Syncfusion support.

It is possible to render a checkbox in the Gantt columns using the editType property and then get the checkbox state in the BatchUpdate method. The column will return a value of true or false based on the checkbox state, which you can use to customize your code as needed.



<e-gantt-column field="verified" headerText="Verified" editType="booleanedit"></e-gantt-column>




public IActionResult BatchUpdate([FromBody]CRUDModel batchmodel)


  if (batchmodel.Changed != null)


    for (var i = 0; i < batchmodel.Changed.Count(); i++)


       var value = batchmodel.Changed[i];

       GanttDataSource result = DataList.Where(or => or.taskId == value.taskId).FirstOrDefault();

       result.taskId = value.taskId;

       result.taskName = value.taskName;

       result.startDate = value.startDate;

      result.endDate = value.endDate;

       result.duration = value.duration;

       result.progress = value.progress;

       result.predecessor = value.predecessor;

       result.resources = value.resources;

       result.parentID = value.parentID;

       result.verified = value.verified;
