Hi All,

           I need Kendo Gantt Chart Export to Excel option how can be do if any example is there please provide me, please help me to provide excel option.

Hi,

I have a task with long name and after exporting it to pdf, name is shown partially.

I tried to change width of the column before exporting and reset it after it:

let columns = $("#gantt").getKendoGantt().options.columns;
columns[3].width = 1500;
$("#gantt").getKendoGantt().setOptions({columns: columns});
outerThis.gantt.saveAsPDF();

but it broke my gantt chart, because I have other methods in databound and databinding which resets after setOptions.

I also tried to change height of my rows, but it broke dependencies like shown in Screenshot(120).

How can I solve this problem? Is there any way to change only the width of the column without changing other things?


Thanks

        display: none;
    }

Hi,

I just upgraded to Kendo UI 2021 R1 version from 2020 R2.

Now I am trying to implement simple predefined (column) views for my gantt widget.

I have approx. 35 possible columns for my gantt and five "config" arrays which define which columns should be visible and in which order (usual case is 5-10 columns visible at the time). I have five buttons which trigger reorder and show/hide columns methods from gantt list.

I made this to work, but this tends to be quite slow specially if my project has many elements in tree.

Just to reorder elements before showing/hiding them, it takes more than half second (closer to 1 sec) per item to reorder as shown below.

measure reorder 0.9938250000122935
measure reorder 0.84582499996759
measure reorder 0.8179099999833852
measure reorder 0.8124349999707192
measure reorder 0.8222400000086054
measure reorder  0.670899999910034

Then, to show desired columns and hide others it takes additional 0.5 sec per hide/show method. (see below)

measure  show 0.5577549999579787
measure  show 0.43599000002723187
measure  show 0.4385149999288842
measure  show 0.42784000001847744
measure  show 0.44247000000905246

measure hide 0.4437199999811128
measure hide 0.440279999980703
measure hide 0.4344099999871105
measure hide 0.43585499993059784
measure hide 0.4289250000147149
measure hide 0.4369650000007823

This results in quite slow response - changing of views takes between 2 (smaller projects) to 10 seconds (medium/bigger projects).

measure table switch 9.914615000016056

Is there any better way to do this or could I simply prepare view in behind and replace current gantt.list.columns array with new one - because this switching logic is not acceptable from performance of point of view.

UPDATE: I tested further - seems that depth and how much tree is expanded is making a big impact on performance.

Thank you and best regards,

Using the code below I can successfully update a gantt task (I'm using a custom edit screen + custom update function). It fires off my transport update handler and axios does the update just fine.

  var task = ganttdataSource1.at(0);
  ganttdatasource1.update(task, { title: "New Title" });
  ganttdatasource1.sync()

  var task = ganttdataSource1.at(0);
  ganttdatasource1.update(task, { 
        title: "New Title", 
        resources: {
            taskId: 111,
            resourceId: 222,
            value: 5,
        } 
    });

  ganttdatasource1.sync()

Hi,

I have added Kendo dropDownList as cell editor to Kendo Gantt. 

After some time, some users reported issue where doubleclick on cell randomly just opens and closes dropdown on its own. 

We did quite a lot of debugging until we were able to reproduce issue. 

It turns out that in some cases (not clear under which conditions) when doubleclick is either too fast or performed on laptop touchpad, it happens almost in 30% of cases.

(We are using kendo UI 2020 R2 version, but issue is reproducible even in latest version).

Issue was reproduced by developer on Dell Latitude 5580 (using touchpad doubleclick), while users reported on other systems.

Here you can find the dojo where issue is reproducible.

https://dojo.telerik.com/aHuDaYup/4

Also, we recorded video on the same dojo, where behavior is demonstrated. 

First 4 clicks are mouse, and next ones are with touchpad. (users were having issues even with mouse)

If there are any things we can do to help, please let me know.

Thank you and best regards.

I was wondering whether the resources are intended only for people/time based resources or if it is ok to use for material/quantity type resources eg. cement, wire etc.

It looks like I can customize the unit number format to show kg, metres

Hello,

First of all, my environment is Angular10, gantt uses Kendo widgets (kendo.custom.min.js), version is 2020.3.1118
I customized a button (Add Child) on the screen. After I added a subtask,then immediately move the newly added task to the inside of another task (+ this type of movement), and then an error (e.taks = undefined), e.task cannot get the value, only in this case an error message will appear, and other moving methods will not appear.

In addition, if I add a task, F5 refreshes the page and moves the task, the above problem will not occur.

The general reason I investigated is because the id of the newly added task is assigned a value of 999. If it is not assigned, there will be no error.

This is the method of my Add Child button:
