Hi Team,

is it possible to use a custom image inside the map control to place markers on?

Next to the world map, we would like to provide some detailed information for buildings and use the building layout to place markers inside rooms.

Thank you very much in advance!

Connection Lines for Map component

Hi Team,

would it be possible to add Connection Lines between markers to the Map component?

The items we place on the map are network devices and it would be great, if we could add an array like double[][] to our items to automatically draw a line to this coordinates to show the connections of our network. It could either be an array of coordinates or a list of objects which are already part of the marker layers data.

Thank you very much in advance!

Best regards,

Drag&Drop for Map component

Hi Team,

would it be possible to add Drag and Drop to the Map component?

We have already a lot of items in our application that we want to place on the map and it would be way easier if we could just drag them from a grid or listview onto the map and then save the retreived coordinates in the items and add them to the marker layers data.

Thank you very much in advance!

Best regards,

TelerikDropDownList doesn't close after selection

I have a telerik dropdownlist that isn't closing after selection. I've looked at the answer posted here: Dropdownlist does not close after selection in UI for Blazor | Telerik Forums, but that doesn't solve my issue. My value fields match (I am using DateOnly), and the value is a Value type (struct).

<FormItem Field="@nameof(HpuDonation.HpuScheduledPickupDate)">
    <Template>
        <TelerikDropDownList Width="150px" ValueField="@nameof(PickupDateTargetCapacity.PickupDate)" Data="@PickupDates" @bind-Value="@Donation.HpuScheduledPickupDate">
            <ValueTemplate>
                @((context as PickupDateTargetCapacity).PickupDate.ToString("MMMM d"))
            </ValueTemplate>
            <ItemTemplate>
                @((context as PickupDateTargetCapacity).PickupDate.ToString("MMMM d"))
            </ItemTemplate>
        </TelerikDropDownList>
    </Template>
</FormItem>

@code {
    public IEnumerable<PickupDateTargetCapacity> PickupDates { get; set; } = new List<PickupDateTargetCapacityDto>();
    public HpuDonation Donation { get; set; }

    public class HpuDonation
    {
        public DateOnly HpuScheduledPickupDate { get; set; }
        // other fields
    }

    public class PickupDateTargetCapacity
    {
        public DateOnly PickupDate { get; set; }
        // other fields
    }
}

Where am I making the error?

Grid filtering without model properties

Hi,

I have a Grid component that is used for editing data in an arbitrary database table. The type of the grid is a class that doesn't have properties for each column, but rather simulates columns and row data based on the selected database table structure. The purpose of this is to enable the user to edit a certain database table without the need to define the exact data structure in the web application.

This works fine when displaying data and editing data. However, I need to implement filtering and things start to get tricky.

I have a snippet that simplifies the issue: https://blazorrepl.telerik.com/weYKFcvq2749nY9L57

Before trying to implement filtering, I had no Field attribute on my GridColumns and that worked fine. But when adding the FilterMode attribute to the TelerikGrid component the filter row isn't rendered at all (also not when using FilterCellTemplate). I've read other forum posts about the necessity of the Field attribute. When I add the Field attribute, the filter row is rendered but I get an exception stating "Value cannot be null. (Parameter 'nullableType')" with this stack trace:

at System.ArgumentNullException.Throw(String paramName)
at System.Nullable.GetUnderlyingType(Type nullableType)
at Telerik.Blazor.Common.Filter.FilterOperatorFactory.GetColumnDefaultFilterOperator(Type propType)

Is the component using reflection to determine the Type of the field? Or can I somehow tell the component dynamically what type to use, in the same way I can return the title or cell content dynamically?

I tried to use the filter template but I get stuck on the Field problem.

FileManager not expose all Upload properties

In the documentation (link) is written that "Configure the integrated Upload through the FileManagerUploadSettings child tag of FileManagerSettings. The FileManager exposes parameter names that are identical to the respective Upload component API members", but the FileManagerUploadSettings expose only a subset of upload properties.

This is a very limitation because we can't customize the upload or support the upload of multiple file.

I think the documentation needs to be correct, or what I would prefer, that all the properties be correctly exposed by FileManagerUploadSettings.

thanks

Turn off TelerikButton enter key

Hi,

We have an issue on our site that when you press an enter key on a second custom grid row (not a Telerik Grid, but rather a foreach that makes a new additive row) it will expand the first row when we press enter on any other row.

We've boiled it down to it possibly being a Telerik A11Y issue.

Is there a way we can stop a the button from reacting to an enter key press?

Kind regards,

Benjamin,
