Hi Team,

I want to get the date range of the current view whenever the scheduler component loads and whenever the user changes the view or changes the date by the navigation button (next, prev, date picker). I need to know the start and end date which is visible on the scheduler. I am able to know the view name by using onViewChange callback and default date by using onDateChange which is giving me the default selected date but I want the whole range (start to end), I am using class-based components.

Scenario: Currently selected view is the month view and the default date is in the month of Feb 2023 so I need something which gives me the start date as Jan 29, 2023, and the end date as March 04, 2023.

Just like In the Jquery version of the scheduler, we get the required information by using the following function:

function scheduler_view_range(e) {
        var view = e.sender.view();

        // The view has:
        // A startDate method which returns the start date of the view.
        // An endDate method which returns the end date of the view.

        $(".console").append("<p>" + kendo.format("view:: start: {0:d}; end: {1:d};", view.startDate(), view.endDate()) + "</p>");
    }

Hi.

I am working with the Scheduler component and I display the WeekView in full day mode. Is there a possibility, that I can somehow achieve to automatically scroll to the work hours when the Scheduler opens? (see attached screenshot)

I know that I can limit the view to show the work hours only but that is not what I want. I just would like to achieve that our users don't have to scroll down everytime the Scheduler opens to see the work hours. Same behavior would be desirable in DayView.

Any help would be appreciated.

Thanks,

Bernd

After server-side validation, I am calling forceUpdate() to update the UI.

But, this isn't "wired" to the FormSubmitClickEvent isValid - or at least not in the same time frame as the onStep function.

Is there a way to tie server-side validation in with FormSubmitClickEvent isValid? Since this process is asynchronous, I'm guessing it will be challenging.

 

... Called after server-side validation to update the UI - this works

setTimeout(() => {
formRef.current.forceUpdate();
});

 

... Called when user clicks the "next" button on the multi-step screen

const onStepClick = React.useCallback(
(event: FormSubmitClickEvent) => {

Let's say we have a grid displaying orders: Order ID, Customer Name, Product Name. The grid is displaying the "ProductName" but filtering needs to be done by "ProductID". If we have thousands of products, we don't want to populate the combobox with everything, but instead might want to use remote data (filtering/virtualization). Most examples I find assume there is local data in some json file. How can we implement a custom grid filter cell that has a combobox that uses remote data?

My understanding is that the filter row is stateless and controlled by the grid. If I implement a custom combobox with remote data as soon as I filter the grid via the GridFilterCellProps onChange, the filter cell state is lost (so no more loaded data matching the selected item) and appears that nothing is selected even though a filter is applied.

I've tried to store the state outside of the filter cell, but I can't seem to get it right. Anyone else have any luck doing something like this?

I'm using the ComboBox component and would like to restrict the values that you can manually enter into the field above the dropdown.

(See screenshot).

I have two scenarios: 

1) Only allow to enter integer values (numeric, no comma or dot allowed), both negative and positive values are allowed;

2) Only allow to enter float values (numeric with comma or dot), both negative and positive values are allowed;

I tried to restrict the input by managing the keyDown event but I'm not sure if this is the right approach.

Do you maybe have an example for me, how I could better solve this?

Thanks!

Greetings,

Bernd

Hi,

We are customising kendo-theme-bootstrap using the build process of our application and Dart Sass as per the Kendo documentation. We have started to see the following warnings when compiling our application:

Is this something we should be concerned about?

Kind regards,

The onBlur event the fires after the user clicks on the date in the calendar popup doesn't contain the value that's now in the datepicker. The onBlur that fires after a date is input to the text box and blurred does contain the value. Without that consistency, I am foreced to use the onChange event which is a very different implementation, which comes with a different set of challenges. Any advice?

Hi, I'm trying to include holidays in my Gantt chart so the project timeline would reflects the impact of holidays on project schedule. 

Below is how I've done so far. However, the timeline is still running on holidays. Please help me.

 let holidays = [
                    new Date (2023, 4, 1),
                    new Date (2023, 4, 4),

                ];

let taskData = [
                    {
                        id: 1,
                        title: "Task 1",
                        orderId: 0,
                        start: new Date("2023-04-30 08:00:00"),
                        duration: 24,
                        percentComplete: 0.45,
                        isExpanded: true,                   
},
                    {
                        id: 2,
                        title: "Task 2",
                        orderId: 2,
                        start: new Date("2023-05-02 08:00:00"),                        duration: 10,
                        percentComplete: 1,
                        isExpanded: true,
                    },
                    {
                        id: 3,
                        title: "Task 3",
                        orderId: 3,
                        start: new Date("2023-05-02 17:30:00 "),                        duration: 10,
                        percentComplete: 0.77,
                        isExpanded: true,
                    },
                ];
                let dataWithEndDate = taskData.map((task) => ({
                    ...task,
                    end: new Date (task.start.getTime() + task.duration * 60 * 60 * 1000),
                }));

render() {
       
        return (
           <div>
               <Gantt
taskData={dataWithEndDate}
                     columns={columns}
                     holidays={holidays}
                >
                </Gantt>
            </div>
       
        );
    }

Hi,

Dropdown is not visible in dialog after upgrade to v5.11.0. It used to work with v5.1.0.

With v5.1.0, dropdown's z-index is automatically calculated based on the dialog's z-index. With v5.11.0, the dropdown's z-index is always 100, which is lower than dialog's z-index.

Please advise.

 

Thanks.
