Our current implementation of the JQuery version of the scheduler uses custom views. I understand that custom views are going to be a difficult if not impossible task for Blazor rendering. The goal for our custom view is simple, we override the calculateDateRange function to supply an ordered date range that allows us to have a "TimelineTwoWorkWeekView", thus showing Monday-Friday then Monday-Friday again. We also had a use case that was never implemented but would be addressed the same way; to show all "mondays this month".

Therefore, the request is a "TimelineCollectionView", displaying a timeline view for dates specified in an IEnumerable<DateTime>.

Any other ideas or feedback would be greatly appreciated.

I am really looking to try to do something like this in Blazor: ASP.NET MVC Scheduler Hierarchical Grouping Demo | Telerik UI for ASP.NET MVC

In MVC, this feature is implemented with the dataParentValueField.

I have a scheduler, and am using a custom Edit handler. I need to support recurrence, and editing recurring events. When the use double-clicks on a recurring event, there is a dialog that asks whether they would like to edit the occurrence or the entire series.

I want to be able to capture the results of this dialog. `SchedulerEditEventArgs` doesn't include any attributes that track this.

===========

===========

The implementation of this enhancement could be covered by either including the corresponding attributes in the SchedulerEditEventArgs or by exposing a Template for the RecurrenceDialog.

Note: You may also check the Ability to directly edit an occurence or the series, without the prompt asking you to choose feature request as the implementation of both features will most likely be covered in one release.

If the Scheduler is placed in a parent container (for example Telerik Splitter or any other container) its appointments are not resized when resizing the pane. The Scheduler itself resizes accordingly, but the appointments don't.

I want to be able to limit the Scheduler to a minimum and/or maximum date.

This request could be revised in two separate tracks:

• Min and Max parameters on component level regardless of the selected view
• Min and Max parameters for the separate views ( Day, Week, Month etc.)

Please share your thoughts on how you'd expect it to be implemented.

Currently, you can only initiate editing/creating of an appointment in the Scheduler on double click. I'd like to be able to trigger these operations on single click.

It will be nice to have EditOn parameter to allow choosing if editing/creating will fire on single or double click of an appointment/slot.

I want to add more fields to the scheduler create/edit popup. Currently, this is possible by creating a custom edit form. However, this customization would be easier if the Scheduler exposed a Popup Form Template similar to the Grid.

A necessary prerequisite for exposing this is to first add a State feature in the Scheduler. This will allow programmatic control over the edited item.

I am using a Scheduler with vertical grouping by multiple resources. In Timeline view, some of the appointments appear with an offset and are not correctly aligned in the cell. In some cases, the appointment is even rendered outside the slot it is associated with.

The issue seems to occur as of UI for Blazor 4.2.0. The same configuration worked fine in 4.1.0.

• working version (4.1.0)...

• not working version (4.2.0)...

I would like an indicator of the current time in the scheduler that updates itself (as often as every minute) without the need to reload the page. Like in the Reach suite: https://www.telerik.com/kendo-react-ui/components/scheduler/views/day/#toc-current-time-marker

You may find interesting this related request for more precise appointment rendering: https://feedback.telerik.com/blazor/1451797-more-precise-representation-of-start-end-times-on-scheduler-exact-time-rendering. If so, Vote for it and Follow it as well.

The following date in the Scheduler RecurrenceRule cannot be parsed and is ignored:

RecurrenceRule = "FREQ=DAILY;UNTIL=20210722T000000"

According to the RFC5545 specification, this should be a valid date format.

These formats will work:

RecurrenceRule = "FREQ=DAILY;UNTIL=2021-07-22T00:00:00"

RecurrenceRule = "FREQ=DAILY;UNTIL=2021-07-22T00:00:00.000Z"

EDIT:

private string TransformRecurrenceRule()
        {
            const string untilSeparator = "UNTIL=";
            var ruleParts = RecurrenceRule.Split(untilSeparator, StringSplitOptions.RemoveEmptyEntries);
            if (ruleParts.Length <= 1)
            {
                // There was no Until clause to worry about
                return RecurrenceRule;
            }

            // Save the first part of the rule
            var ruleBeginning = ruleParts[0];

            // Split the date part of the until clause from any following clauses
            var remainingClauses = ruleParts[1].Split(';', 2, StringSplitOptions.RemoveEmptyEntries);

            //Save the date part of the until clause
            var untilDate = remainingClauses[0];

            // Save any following clauses with the `;` replaced
            var ruleEnding = "";
            if (remainingClauses.Length == 2)
            {
                ruleEnding = $";{remainingClauses[1]}";

            }

            // Convert the until date into .net parsable format
            const string format = "yyyyMMddTHHmmss";
            var date = DateTime.ParseExact(untilDate, format, CultureInfo.InvariantCulture);
            var dateStr = date.ToString("yyyy-MM-ddTHH:mm:ss");

            // recombine rule components
            var newRuleParts = new[] {ruleBeginning, untilSeparator, dateStr, ruleEnding};
            var newRule = string.Join("",newRuleParts);

            return newRule;
        }

Hi, 

is there a way to use the scheduler to display a month ?

Something similar to this https://docs.dhtmlx.com/scheduler/how_to_start.html

I could have a case where the work week starts on Sunday and ends on Thursday, and I want to be able to denote this in the scheduler.

ADMIN EDIT

For the time being, you can consider two options (separately or together):

• use the Multi-day view to make only the desired days visible in the scheduler (its NumberOfDays parameter combined with the scheduler's Date parameter control the start date and how many days will render)
• use CSS like this to remove the darker coloring for non-working slots so that there isn't a visual distinction that is wrong:

      div.k-scheduler .k-scheduler-nonwork,
      div.k-scheduler .k-nonwork-hour {
          background-color: inherit;
      }

---

is it possible to drag between hours to create a new appointment like in the attached recording? 

Is this available for blazor? if not could it be added somehow temporarily until support for it is added?
