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.

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.

When a culture that has comma for decimal separator is used, the ColorPicker formats the rgba() CSS rule as rgba(255,255,255,0,6) which is incorrect. The alpha value should always have a dot as a decimal separator.

<TelerikColorPicker @bind-Value="@value">

@code {
    public string Value { get; set; } = "#282f89";
}

Set the culture of the application so that the default decimal separator is a comma (el-GR).

// in Program.cs file
CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("el-GR");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("el-GR");

The rgba() rule is formatted as rgba(255, 255, 255, 0,6) but should be formatted as rgba(255, 255, 255, 0.6).

Hi Telerik team,

When I want to bind the Blazor Grid to an ExpandoObject I need to assign the FieldType. I know I have to use non-nullable types.

But I want to use nullable types (for example int?) to have a blank cell within the Grid when there is no value for it. With "typeof(int)" instead of "typeof(int?)" every empty cell shows "0" which I don't want.

Is there any chance to let FieldType accept nullable types?

Best regards,

Rayko

Add a setting similar to the AllowUnsort so that I can disable the unsorted state of the Grid.

ADMIN EDIT:

Here is how to achieve this with the Grid state.

Initially, the grid is filtered by "Is FTE? = True". It shows 20 lines. The sum of "Hours" should be 800. But the footer shows another value (depends on the random logic which you've implemented). See the attached screenshot.

Then, when changing the filter, the correct sum is shown.

But I need the correct value initially...

Re: I've just found out that using the OnRead event instead of the standard data binding solves the issue. Better said, it's a possible work-around.

When a filter descriptor is created and the value is of type DateTime? (nullable DateTime) the serialized value is incorrect.

    DataSourceRequest request1 = new()
    {
         Filters = new[] {new FilterDescriptor("Test", FilterOperator.IsEqualTo, DateTime.Now.Date) {MemberType = typeof(DateTime)}},
         Sorts = new List<SortDescriptor>()
    };

    DataSourceRequest request2 = new()
    {
         Filters = new[] { new FilterDescriptor("Test", FilterOperator.IsEqualTo, DateTime.Now.Date) { MemberType = typeof(DateTime?) } },
         Sorts = new List<SortDescriptor>()
    };

    string query1 = request1.ToODataString(); // outputs $count=true&$filter=(Test%20eq%202022-05-12T00:00:00.0000000Z)&$skip=0
    string query2 = request2.ToODataString(); // outputs $count=true&$filter=(Test%20eq%202022-05-12%2000:00:00)&$skip=0

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.

I need to allow users to position a map marker on the map. As such, I need them to be able to drag the marker and/or map but I don't see any drag events documented.

How do I support user marker positioning with interactions like a drag, drop, click, etc.?

Here is our scenario. The use case is for servicing automobile breakdowns. We use the browser to guess the user's location but it may not be correct, either by a little or a lot:

1. The map is initialized with the current device location.
2. The user is asked to confirm the location or reposition the "me marker" to locate the actual position of their vehicle.
3. The user can drag their marker to the actual location.
4. The app records the latitude and longitude of the dropped marker.

We expect users to be on small format devices for this, and precise location data is critical (e.g. on the freeway or a road going under the freeway).

When using an abbreviated month in the date format, the picker will not automatically move to the next element (year) after entering a month. If I enter 04 for example, the focus remains on the month.

When using a numeric month in the date format, the picker will automatically move to the year after entering a month.

See an example: https://blazorrepl.telerik.com/cmOzPgFc08d1woml09.

If there are many subfolders below a folder the list becomes too long for the TreeView window and gets cut off at the bottom. Apparently, there are some height and overflow settings missing. After some digging around in the rendered HTML and copying some CSS selectors (using F12 on Edge) I got it working with this in my CSS file:

.k-filemanager-content-container > div > div.k-pane.k-filemanager-navigation.k-pane-static > div > div > ul {
    height: 100%;
    overflow: auto;
}
.k-filemanager-content-container > div > div.k-pane.k-filemanager-navigation.k-pane-static > div > div {
    height: 100%;
}

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

In the meantime, here is a possible workaround:

<style>
 .k-treeview-lines {
        height: 100%;
 overflow: auto;
    }

    .k-filemanager-treeview {
        height: 100%;
 }
</style>

Hello,

First of all: thank you for implementing the Excel like filtering with the new CheckBox Filter! This was a feature that was highly sought after in our development team.

But there is one thing I am missing: the checkbox list has no option for sorting.

If we want to sort our filters now we have to implement the FilterMenuTemplate in every column that has filtering active (which are a lot) and define the list with filter options and filter it ourselves. 

Is this something that can be fixed easily?

ADMIN EDIT

We will probably sort ascending the values by default (out-of-the0box), and any other custom sorts should be implemented through the filter menu template.
