RecurrenceRule BYDAY not working

Hello,

I have a CalDav-Server as data storage for caldav-clients. One client frontend is the Telerik Scheduler.

I have created an event series with end date like this:

RecurrenceRule = "FREQ=DAILY;UNTIL=2022-08-13T23:59:59"

which works fine.

But a RecurrenceRule like this:

RecurrenceRule = "FREQ=DAILY;BYDAY=MO,TU,WE,TH,FR"

works on other clients (like Thunderbird), but in the Scheduler it produces the same result like:

RecurrenceRule = "FREQ=DAILY"

Did I something wrong with the rule or is there a problem with the Scheduler?

Grid: SelectedItemsChanged not firing when in EditMode

Long story short:

The SelectedItemsChanged-Event is not firing when the Grid is in EditMode like "GridEditMode.Incell".

When the EditMode is "GridEditMode.None" it works just fine.

Is this a bug or a feature ?

Adding scrollbar to FilterFields

My app has a long list of possible fields to filter on. The dropdown box for the fields exceed the height of the page so a scrollbar would be nice.

Can you point out the class styling that needs to be updated? I just added arbitrary number of fields to the Filter demo.

<TelerikFilter Value="@Value" ValueChanged="@OnValueChanged">
    <FilterFields>
        <FilterField Name="@nameof(OrderDetailDto.OrderId)" Type="typeof(int)" Label="Id" />
        <FilterField Name="@nameof(OrderDetailDto.Quantity)" Type="typeof(short)" />
        <FilterField Name="@nameof(OrderDetailDto.OrderFreight)" Type="@typeof(decimal)" Label="Freight" />
        <FilterField Name="@nameof(OrderDetailDto.OrderShipCountry)" Type="typeof(string)" Label="Country" />
        <FilterField Name="@nameof(OrderDetailDto.OrderShipName)" Type="typeof(string)" Label="Ship to" />
        <FilterField Name="@nameof(OrderDetailDto.OrderShipAddress)" Type="typeof(string)" Label="Ship Address" />
        @for (int i = 0; i < 25; i++)
        {
            <FilterField Name="@i.ToString()" Type = "typeof(string)" Label="@i.ToString()" />
        }
    </FilterFields>
</TelerikFilter>

Optional Column Header Template

Is there a way to have the column header template be optional? Depending upon some values in my data, I might need to use a header template for a specific column, otherwise, I would like the have the default behavior.

I tried placing an if statement inside the <GridColumn/> element like this:

<GridColumn Field= "" FieldType="" >
     @if (_useHeaderTemplate)
     {
         <HeaderTemplate></HeaderTemplate>
     }
</GridColumn>

This results in a compile error of "Unrecognized child content inside component ...."

I then tried

<GridColumn Field= "" FieldType="" >
     <HeaderTemplate>
          @if (_useHeaderTemplate)
          {
            <div>Custom Header</div>
          }
     </HeaderTemplate>
</GridColumn>

This results in no text being rendered for the column header.

I'm trying to avoid (a) duplicating the <GridColumn/> configuration for both the true and false evaluations of the if statement; (b) I don't want to take over the complete rendering and management of the grid column header. I still want the framework to handle that.

Thanks

-marc

Alphabetic pages for Pager Control

Is there a way to have the pager control display alphabetic pages instead of numeric? I would like to provide to my users a contacts book where it is displayed alphabetically based on contacts name. If not this might be a suggestion for a new control. I am thinking a modern day rolodex.
