how to control the startdate and enddate on add new task on Gantt control

[Dwayne Boykin]

Hello,

How to control the startdate and enddate on add new task on Gantt control?

I cannot find a server event on Gantt control to allow me to grab the StartDate/EndDate textbox from code behind.

Thank you

Hi Dwayne,

We can control the start Date and End date while adding a new task and set the date returned from code behind using ActionComplete client side event. Please find the code example for details.

<ej:Gantt ID="Gantt" runat="server"

ActionComplete="ActionComplete">

<AddDialogFields>

              <ej:AddDialogField Field="Id" />

              <ej:AddDialogField Field="Name" />

              <ej:AddDialogField Field="PercentDont" />

          </AddDialogFields>

</ej:Gantt>  

function ActionComplete(args) {

                var ganttObj = $("#Gantt").data("ejGantt");

                if (args.requestType === 'save' && args.addedRecord) {

var ganttRecord = args.addedRecord.item;

                    if (args.addedRecord.parentItem)

                        ganttRecord["ParentId"] = args.addedRecord.parentItem.taskId;

                    $.ajax({

                        type: "POST",

                        url: "GanttSample.aspx/getDate",

                        contentType: "application/json; charset=utf-8",

                        dataType: "json",

                        success: function (result) {

                            ganttRecord.StartDate = result.d.startdate;

                            ganttRecord.EndDate = result.d.enddate;

                            PageMethods.AddIt(ganttRecord);

                            var obj = $("#Gantt").data("ejGantt");

                            obj.reRenderChart();

                        },

                        failure: function (response) {

                            alert(response.d);

                        }

                    })                 

                }

}

public class date

        {

            public string startdate { get; set; }

            public string enddate { get; set; }

        }

        [WebMethod]

        public static date getDate()

        {

            date gantt = new date();

            gantt.startdate = "02/27/2014";

            gantt.enddate = "02/29/2014";

            return gantt;

        }

We have also prepared a sample based on this and you can find the sample under the following location.

Thanks for your response.

 

Can you pre-populate the State/End date before save the task?

 

Your sample code is populate Start/End date while saving the task.

 

Thank you
