How to enable "Zoom to Fit" as a one time action, as opposed to having it constantly on?

[Shane Mc Inerney]

Hi,

I am having an issue with the gantt control.

When I click zoom to fit in the tool bar, it displays fine. The issue is when I make a change to the data on the gannt, the zoom to fit is reapplied.

Is it possible to stop it from continuously reszing to "Zoom to fit"? Ideally it would only happen one time when the user clicks the zoom to fit button.

I have attached a zip file containing a video displaying the issue I am describing. As you can see the chart zoom "jumps" when I update the task bar.

I want to avoid this if possible, ideally zoom to fit would be a once off action triggered by the user.

Any help on this would be greatly appreciated

Hi Shane,  

  

 We can resolved the reported problem by using fitToProject method after edit action completes using taskbarEdited and actionComplete event.  

   

taskbarEdited: function(args){  

              if (args) {  

                var obj = document.getElementById("Zooming").ej2_instances[0];  

                obj.dataSource = zoomingData;  

                obj.fitToProject();  

              }  

            },  

actionComplete: function (args) {  

              if (args.action === "CellEditing" && args.requestType === "save") {  

                var obj = document.getElementById("Zooming").ej2_instances[0];  

                obj.dataSource = zoomingData;  

                obj.fitToProject();  

              } else if (args.action === "DialogEditing" && args.requestType === "save") {  

                var obj = document.getElementById("Zooming").ej2_instances[0];  

                obj.dataSource = zoomingData;  

                obj.fitToProject();  

              }  

            }
