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.

Greetings,

I am curious if you intend on offering any means of control for the height of an appointment cell within the scheduler. For us it is in the Timeline view with Resources. I have downloaded the source code and implemented the functionality myself and am willing to share my changes. It ultimately performs three functions:

1. Creates a new parameter on the SchedulerTimeViewBase.cs so that it is end user facing.

2. Alters the code in the ContentTableBase.cs to assign the AllDayAppointmentOuterHeight property with this new parameter's value (plus 1).

3. Alters the AppointmentRendererBase.cs to assign the AllDayAppointmentHeight property with this new parameter's value.

Additional changes are necessary to the Models and Interfaces.

We have used the JS version of this for several years and need the additional real estate on the scheduler. This is the only means that I could figure to alter the height as the position of the cells and resource rows are computed on the back end. Any alterations using a CSS class during OnItemRender will produce cells that overlap each other and/or overflow to subsequent rows.

Hello,

Nice work on the FileManager component, this will be incredibly useful. I would like to use this control in an Open File Dialog and the only thing I'm missing to support that is what is the selected item in the listview. If I could bind that selection then I could enable/disable my Ok button and provide the selected item(s) when the user hit's ok. Is there a way to access this information?

Thanks,

-Andy

I bind the TelerikEditor Value to a property that is reloaded with different unrelated content. The editor keeps the Undo/Redo stack so for the "second" content I can Undo back to the "first" content. I'd like to be able to clear the Undo stack.

As a user, I would like to ability to pin one to many row(s) in a grid so that the pinned rows are always the first rows at the top of the grid.

If a filter is applied, the pinned records that match the filter should be displayed first.  Non matching rows may be hidden.

If a column sort is changed, the pinned rows should be sorted then the unpinned rows should be sorted to ensure the pinned rows are always at the top of the grid.  

As a developer, Pinning should be a optional feature configured when the grid is setup.

This essentially would only add a data populated "pin" column the user can toggle on or off, but the real effort in this request is around the sorting and filtering to ensure when the user clicks a column the event is captured, and the sort is submitted as pin column, then the selected column, to ensure the pin takes precedent.  

Hi,

  I had to figure this out myself for the ComboBoxSettings because there is no documentation for this. 

  The MinWidth works from the Combobox width or greater extending the size of the popup and

   MaxWidth only creates a popup width of the Combobox only. 

Please document this feature and how to use it.  And, is this intentional because it wasn't intuitive for me to figure out.

I created a REPL for you to test this out for yourself.

All I ask is to give a way to have a proper working datepicker. Like your javascript datepickers. That doen't care only for right values but for the person that uses it. Telerik was an early adopter in the Blazor ecosystem, I don't know how they haven't yet fixed their datepickers.

You can do this with many ways. I don't know them all but I will propose some here.

1. Create a second datepicker component that works properly.
2. Put an attribute in the component to work with free-text
3. Maybe if this attribute is on you can switch behind between 2 different components
4. Find a other solution of your own.

In the end behind the scenes you shouldn't bind the datepicker input in the datetime property but to a sting one. DevExtress has done this right.

This will solve

1. Proper user expirience when a user uses the keyboard to edit dates
2. Copy-Paste issue
3. Clear date parts issue
4. all from 30/4/2022 to edit to 31/5/2022 with out having to clear the input
5. Strange editing of years (I have an example in the end)
6. Allow to have dots or what ever the users want between dates numbers. (e.x. 13.3.2022 )

I this is a trade-off and you will have senarios with wrong inputs and other things, but you already know them from the javascript world, and it's less importand than the aboves.

*Strange editing of years

Lets say that we have the year 1998 19and we want to put 2014.

the users See
-> 1/1/1998
-> 1/1/9982
-> 1/1/9820
-> 1/1/8201
-> 1/1/2014

That's not user friendly, and is very disturbing.

The idea of the feature is to be able to customize the list of FilterOperators displayed in the list of the FilterRow and FilterMenu.

Currently, the validation of the grid can be disabled altogether via the GridValidationSettings.Enabled option. However, we cannot control the validation of the grid per column.

Also, we cannot control when the validation is triggered. The simple inputs expose the ValidateOn option, but it cannot be set to the default editors of the grid without the need for an explicit declaration of a custom editor.

My users want to paste dates in the date inputs (date pickers in our case). This seems to work in Kendo, but does not work in Blazor, even when the format of the copied data matches the Format of the component.

<p>
    Try copying this date which is valid in the current format: 23/03/1998
    <br />
    then paste it in the date picker and see what happens to the <code>TheDate</code> field
</p>

@TheDate
<br />

<TelerikDateInput @bind-Value="TheDate" Format="dd/MM/yyyy" /> @TheDate.ToString("dd/MM/yyyy")

@code {
    DateTime TheDate { get; set; } = new DateTime(2019, 11, 27, 02, 03, 44);
}

ADMIN EDIT

Allowing the paste into the DateInput (and by extension date picker,...)  would have a lot of cases to control and that is why we have not yet enabled it. If the format is M/d/yyyy, for example, validation for numbers lower or equal to 12 would not be possible when the month is regarded. If the user pastes 8/2/2020 could mean two things - 8th of February 2020 or 2nd of August 2020. This might cause issues as the data that goes to the database might be incorrect and causing the application to misbehave.

That being said, how would you suggest handling the pasting of dates in the component. How would you like from us to handle the format difference of the dates? Please comment below.

Hi, It is possible to have a component that enables the use of the camera and to be able to scan barcodes or QR (1D  & 2D), for Blazor Web assembly and Blazor Server Side. Now this require JavaScript library like as QuaggaJS.

I think that having such a component is very useful and will allow you to build applications with advanced functionalities, other companies offer but only to generate barcodes or QR codes.

We need this existing control in a Blazor based control:

We'll need to fall back to MudBlazor who does support this control.

We are existing licensed users under AVEVA.

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.

Hi Telerik Team,

One of the requirements for my team project is that the ComboBox needs to be sorted in descending order to list dates. We need to sort the groups and the options inside the groups.

Ideally, the ComboBox can have a SortDirection parameter that defines the order as SortAscending or SortDescending, and can display the ComboBox groups and options accordingly.

The need to right-click a file to be able to download it is a bit less intuitive.

I would like to be able to download a file by double-clicking it, or, more generic, to be able to add a double click handler so I can decide what to do with it.
