Overriding task progress of gantt with custom

[Nivedita Vijaivergiya]

Hi,

Currently Gantt calculate parent task progress according to its child task. But i want assign progress to every level task on the basis of calculation done by us(according to our logic).

How can i override gantt calculation for progress?

Thanks,

Nivedita

Hi Nivedita, 

During load time we can render Gantt with custom progress logic by using “load” and create client side event. Using actionComplete client side event we can update custom progress on add/edit/delete action. 

Please find the code example below: 

$("#GanttContainer").ejGantt({ 

actionComplete: function (args) { 

                    //To update the parent fields on edit action 

                    if (args.requestType == "recordUpdate" && !progressEdit) {                        

                        update(args.data.parentItem); 

                    } 

                    //To update the parent fields on add action 

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

                        update(args.addedRecord.parentItem); 

                    } 

                    //To update the parent fields on delete action 

                    if (args.requestType == "delete") { 

                        update(args.data.parentItem); 

                    } 

 

                }, 

}); 

      function update(parentItem) {           

            if (parentItem != null) { 

                //custom logic for parent item 

              parentItem.status = Math.round(parentItem.status +2); 

              parentItem.progressWidth = (parentItem.width * parentItem.status) / 100; 

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

              treeGridObj = ganttObj._$treegridHelper.data("ejTreeGrid"); 

              ganttChartObj = ganttObj._$ganttchartHelper.data("ejGanttChart"); 

                ganttChartObj.refreshRow(ganttChartObj.model.updatedRecords.indexOf(parentItem)); 

                treeGridObj.refreshRow(treeGridObj.model.updatedRecords.indexOf(parentItem)); 

                return update(parentItem.parentItem); 

            } 

        }      

We have prepared the sample and rendered Gantt with custom progress. Please find the sample from below location
