Currently, I'm using your Calendar component for a vacation request feature. It works decently for picking dates in that I can use CTRL and Shift to select many dates. I'm currently making the page responsive but the mobile user experience lacks because there is no way to select more than one date.

The ideal user experience would be to be able to single click (or tap from mobile) to select a date and be able to do that on as many dates as preferred (to select many). Clicking/tapping again would deselect the date. That would be better in both the desktop and mobile versions and more intuitive for a user (as no one has initially assumed CTRL and Shift work - I have had to train them).

In the Calendar documentation, it says that we can selected multiple dates either by holding Shift to select a range or holding control to select multiple individual dates.

Expected behavior (Windows & Mac):

* Shift - Range Select

* Control - Individual Multiple Selection

Result (Windows):

* Shift - ✓

* Control - ✓

Result (Mac):

* Shift - ✓

* Control - ✖

Explanation:

On Mac holding control and selecting a date toggles a right-click (displays options menu), I cannot seem to be able to select more than one date with holding control down.

For example, if you want to prevent the user from selecting all dates prior to February 2021 you can set the Min parameter to new DateTime(2021, 2, 1). In this case, if you navigate to 2022 and then try to navigate back to 2021 through the Decade view, it is not possible, you can only select future year. 

Pressing the Today button works as expected.

Meanwhile, if you want to disable all past dates, a workaround you may try is handle the OnCellRender event of the Calendar and add a CSS class to the cells to style them as disabled. The sample below demonstrates how to achieve that.

<style>
    .not-allowed-cell {
        pointer-events: none;
        cursor: not-allowed;
        background-color: whitesmoke;
        opacity: 0.6;
    }
</style>

<TelerikCalendar @bind-Date="aDate" OnCellRender="RenderCell"></TelerikCalendar>

@code{
    DateTime aDate { get; set; } = DateTime.Now;

    void RenderCell(CalendarCellRenderEventArgs args)
    {
        switch (args.View)
        {
            case CalendarView.Month:
                if (args.Date < DateTime.Today)
                {
                    args.Class = "not-allowed-cell";
                }
                break;
            case CalendarView.Year:
                if (args.Date.Month < DateTime.Today.Month && args.Date.Year == DateTime.Today.Year)
                {
                    args.Class = "not-allowed-cell";
                }
                break;
            case CalendarView.Decade:
                if (args.Date.Year < DateTime.Today.Year)
                {
                    args.Class = "not-allowed-cell";
                }
                break;
            case CalendarView.Century:
                if (DateTime.Today.Year - args.Date.Year >= 10)
                {
                    args.Class = "not-allowed-cell";
                }
                break;
            default:
                break;
        }
    }
}

Hi,

I try to implement a calendar there i use Range selection mode. I want the user only to click on the start range and then we will set end range in code based on the start range date. 

So i have set an RangeStartChanged event handler and that works but the gui component think i am in select end Range date so i want to exit the selection state after i have select Start date.

Is there anyway to do that?

A possible workaround for the time being - use Multiple selection mode of the Calendar and simulate Range selection. Handle ValueChanged event, programmatically add the desired count of dates to the selection and style them as range: https://blazorrepl.telerik.com/cQuzvKbO29J2Tbnt04.

When a calendar is used in range mode the Today button only sets the start date meaning the user has to then click the end date or its value is unknown.

The end date should be set to something, for me id prefer it to set both the start and end to the current date.

You can see this behaviour on the demo pages by just clicking the today button on the range demo. https://demos.telerik.com/blazor-ui/calendar/selection

The calendar viewshows one row too much if the month only has 5 weeks. Please check the attached screenshots.

Steps to reproduce this behaviour:

Just use a regular calendar control and check a month that has 5 weeks only.

E.g. December 2019 if a culture with a week start of Sunday is selected or November 2019 if a culture with a week start of Monday is selected.

Try to use a Calendar (@bind-RangeStart, @bind-RangeEnd) and Date Input (@bind-value) with the same value bound to them. You can't correctly change the date upon input, it shows only today's date.

-------------------- ADMIN EDIT --------------------

The workaround for such a scenario is to not use the @bind-RangeStart, @bind-RangeEnd in Calendar with the same value as Date Input @bind-value. See the code below.

Razor:

<TelerikCalendar Views="1"
                 View="CalendarView.Month"
                 SelectionMode="CalendarSelectionMode.Range"
                 RangeStart="@StartTime"
                 RangeEnd="@EndTime"
                 RangeStartChanged="@((DateTime value) => { StartTime = value.Date + value.TimeOfDay; })"
                 RangeEndChanged="@((DateTime value) => { EndTime = value.Date + value.TimeOfDay; })">
</TelerikCalendar>
<br />
START DATE: @StartTime
<br />
END DATE: @EndTime

<br />

<TelerikDateInput @bind-Value="@inputTimeForStartDate" OnBlur="@OnBlurHandlerFirst" Format="hh:mm">
</TelerikDateInput>

<TelerikDateInput @bind-Value="@inputTimeForEndDate" OnBlur="@OnBlurHandlerSecond" Format="hh:mm">
</TelerikDateInput

C#:

DateTime inputTimeForStartDate { get; set; }
DateTime inputTimeForEndDate { get; set; }

public DateTime StartTime { get; set; }
public DateTime EndTime { get; set; }

private void OnBlurHandlerFirst()
{
    StartTime += inputTimeForStartDate.TimeOfDay;
}

private void OnBlurHandlerSecond()
{
    EndTime += inputTimeForEndDate.TimeOfDay;

Basically want to do the same thing as on the following two demo pages:

Kendo UI already has this feature:

https://demos.telerik.com/kendo-ui/calendar/template

DevExpress UI for Blazor already has this feature:

https://demos.devexpress.com/blazor/Calendar#DayCellCustomization

Checked the documents but this doesn't seem supported yet, is that the case / is this something we could get implemented if so?

Many thanks,

I'm finding it hard to follow what month is what when using multi month views. It would be better if the month appeared above each month view. Where can I put a feature request in for this?
