Hi,

we are having a hard time to come up with a general application layout (menu/navigation).

We found PanelBar, Menu and Drawer... are there any other controls related to menu & navigation?

A more UX oriented documentation (and not only for the technical components individually) would be nice e.g. like they do it here: Overview | Clarity Design System

Kind regards

Steffen

Hi,

Would be great if there could be a Timeline component for Blazor. Just like the Timeline component for WPF at "https://docs.telerik.com/devtools/wpf/controls/radtimeline/overview".

I need that component or something similar to show time based instances of activity on a particular item. A lack of such visualisation feature is making us hold on to the WPF one. 

Thanks.

<TelerikDatePicker Id="startDate" @bind-Value="@StartDate" Width="160px" Format="dd-MMM-yy"></TelerikDatePicker>

DateTime StartDate=DateTime.Now

When our users type to click on the year and type another one they lose one of the digits - so if they try typing 19 or 18 for instance then it sets the date to year 01

It would be nice to switch the color schemes used by the telerik Blazor components on-the-fly in an application (i.e. switch from light mode to dark mode). I realize you have a JS approach to this problem, however that requires maintaining multiple stylesheets and custom javascript, which we are trying to avoid in a Blazor project. I like the approach used by MudBlazor where basically all css colors are variables that can be easily switched at runtime without any javascript:

When filtering or editing a Grid with enum data, the Name property of their Display parameter is respected.

However, in the initial view mode of the Grid the Name property is not applied and the enum values are rendered regardless of whether or not their Display parameter has a Name property defined.

In the meantime, a workaround you might try is to create a custom method to check whether Display attribute is defined and get and display its Name property, otherwise display the Enum's member name.

You can then use a Template for the column that uses enum data, cast its context to the model you are using and invoke the method on the field containing the enum. The sample below demonstrates how you can achieve this.

@using System.ComponentModel.DataAnnotations
@using System.Reflection

<TelerikGrid Data=@MyData EditMode="@GridEditMode.Inline" Pageable="true" Height="500px"
             OnUpdate="@UpdateHandler" FilterMode="@GridFilterMode.FilterRow">
    <GridColumns>
        <GridColumn Field=@nameof(SampleData.ID) Editable="false" Title="ID" />
        <GridColumn Field=@nameof(SampleData.Name) Title="Name" />
        <GridColumn Field=@nameof(SampleData.Role) Title="Position">       
            <Template>
                @{
                    var currentEmployee = context as SampleData;
                    var currentRole = GetDisplayName(currentEmployee.Role);                        
                }

                @currentRole
            </Template>
        </GridColumn>
        <GridCommandColumn>
            <GridCommandButton Command="Save" Icon="save" ShowInEdit="true">Update</GridCommandButton>
            <GridCommandButton Command="Edit" Icon="edit">Edit</GridCommandButton>
        </GridCommandColumn>
    </GridColumns>
</TelerikGrid>

@code {
    //custom method to check whether Display attribute is defined and get and display its Name property, otherwise display the Enum's member name
    public string GetDisplayName(Enum val)
    {
        return val.GetType()
                  .GetMember(val.ToString())
                  .FirstOrDefault()
                  ?.GetCustomAttribute<DisplayAttribute>(false)
                  ?.Name
                  ?? val.ToString();
    }


    public void UpdateHandler(GridCommandEventArgs args)
    {
        SampleData item = (SampleData)args.Item;

        //update the view-model
        var index = MyData.FindIndex(i => i.ID == item.ID);
        if (index != -1)
        {
            MyData[index] = item;
        }

        //perform actual data source operations here
    }

    //model and dummy data generation
    public class SampleData
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public Role Role { get; set; }
    }

    public enum Role
    {
        [Display(Name = "Manager")]
        ManagerRole,
        [Display(Name = "Employee")]
        EmployeeRole,
        [Display(Name = "Contractor")]
        ContractorRole
    }

    public List<SampleData> MyData { get; set; }

    protected override void OnInitialized()
    {
        MyData = new List<SampleData>();

        for (int i = 0; i < 50; i++)
        {
            MyData.Add(new SampleData()
            {
                ID = i,
                Name = "name " + i,
                Role = (Role)(i % 3) // just some sample to populate initial values for the enum
            });
        }
    }
}

Hi, 

I reported this last week but it got declined ??  Perhaps a picture will help

The default grid displays the filter icon OVER the text and this makes the text unreadable.  This is just the material format from your websites themebuilder

The icon should be closer to the column width adjuster - as you can see from the attachment there is more space between the columns than there is text

I would expect it to be  "| Description  Y |"  and not "|  Desc... Y        |" which is what its doing.  (really the space between the filter icon and the column adjusted is just wasted and there seems to be no way to fix it)

I've tried to move the k-i-filter using CSS and while giving it a left margin of 32px is working ok and making it look reasonable, it still has the circle highlighter when you click it in the wrong place and I can't figure out how to move that also.

There doesn't seem to be a way to deselect the selected row either by clicking on a selected row again or by two-way-binding and setting it to an empty list.

This would be pretty handy as currently the only way that makes sense for me is to make no use of selection mode at all.

Hi,

I have a grid, it has quite a few columns - maybe 10-15, and this is causing 2 problems which are kind of related.

First problem is it tries to squash them all onto the screen making them all narrow and that hides the header text - I have played with horizontal scrollbar but so far I've only managed to resize them after it loads (or to workaround that I have tried save state after I've resized them with some success, but i'd really prefer the default starting point to be wider than the screen - if you have an example you can show me how to do this?)

Next problem is when I add a filter row to it - its basically unusable.  Even though the columns are narrow, they look like they should be wide enough, but instead what happens is the filter button appears in the middle by itself and nothing else appears - sometimes I see " ___ Y      "  but most of the time its "        Y         ".  It seems very poor use of space by default.  This is the material theme. 

Can you help?  I did try with the filter menu but it is more complicated for our users and they prefer the idea of filterrow, plus it also crashes intermittently (see below for callstack).

The following should let the multiselect render above the custom yellow element, but it does not. A workaround is available as the second CSS snippet that you can uncomment.

<style>
    /*should work but does not*/
    .high-zindex {
        z-index: 124;/*note how this is higher than the z-index of the div element, and is higher than the default z-index of the component*/
    }

    /*workaround*/
    .k-animation-container {
        z-index: 15000;
    }
</style>

<div style="position: absolute; z-index: 123; width: 600px; height: 200px; background: yellow;">
    <TelerikMultiSelect Data="@Countries"
                        @bind-Value="@Values"
                        Placeholder="Enter Balkan country, e.g., Bulgaria"
                        ClearButton="true" AutoClose="false"
                        PopupClass="high-zindex">
    </TelerikMultiSelect>
</div>

@code {
    List<string> Countries { get; set; } = new List<string>();
    List<string> Values { get; set; } = new List<string>();

    protected override void OnInitialized()
    {
        Countries.Add("Albania");
        Countries.Add("Bosnia & Herzegovina");
        Countries.Add("Bulgaria");
        Countries.Add("Croatia");
        Countries.Add("Kosovo");
        Countries.Add("North Macedonia");
        Countries.Add("Montenegro");
        Countries.Add("Serbia");
        Countries.Add("Slovenia");

        base.OnInitialized();
    }
}

It would be really cool to be able to edit documents much like the WPF syntax editor.

Our use case is that we use blazor for our admin tools and we need to give a better look and feel (color coding) to some stored SQL and XML.  Nothing fancy just a better experience.

I see a good solution for angular (PopupSettings.appendTo)

https://www.telerik.com/forums/datepicker-doesn%27t-open-in-ionic-modal#5117655

but blazor only has the PopupClass attribute to work with.  Assigning that a class with a large z-index didn't help

I'm looking for what you have in WPF as we migrate ourselves over to Blazor - https://www.telerik.com/products/wpf/conversational-ui.aspx

For the time being, you can consider using the Kendo Chat widget as described in this sample project.
