Hello Telerik Team,

When i tried to bound Grid to a ExpandoObject or DataTable  I can't use filter properties .It throws unhandling Exception error. How to sort out this issue.

I'm in need for an OnRendered event (or similar) for a TelerikWindow component. Actually, it would be nice to have for all Telerik blazor components. I this particular case I need to know when a specific <div> is avaible to the browser DOM so that I can call some javascript interop on it. In this case I need to show I leaflet map in the modal window.

I solved it for now, using a javascript timeout of 0.1 second, but that is bad coding.

Hi

Is there a better way to add an automated permission than replacing an existing component type?
How else can I automatically check permissions on the base component "TelerikButton" instead of "MyTelerikButton"?
With a large number of thousands of fields, it does not want to fill the Enable/Visible per field.

My question is not only about permissions, but also about the ability to extend TelerikButton with its my additional [Parameter] which is not included in the basic set.

I would be grateful if you could suggest a better solution.

@foreach (var item in ListOfItemNames.Take(200))
 {         
     <div class="row">
         <div class="col">
             <label for="@item">@item</label>
             <MyTelerikButton Id="@item" Form="Device" Icon="SvgIcon.Stop" Title="@item" OnClick="@ButtonAction" ButtonType="ButtonType.Button" />
             <MyTelerikTextBox Id="@item" Name="Device"  Value="@item"></MyTelerikTextBox>
             @* ...<Telerik...> etc *@
         </div>
     </div>
 }

My Component

public  class MyTelerikButton: TelerikButton
{
   
    [CascadingParameter (Name = "Privileges")]
    public required List<Privilege> Privileges { get; set; } = [];

    protected override void OnInitialized()
    { 
        base.OnInitialized();
        var buttonName = Form + Id;
        Enabled = Privileges.Any(x=>x.Code == buttonName);       

    }
}

Hi,

I try to use Telerik.UI.for.Blazor in Docker.

I have added a nuget.config file and also add the corresponding line as explained here

https://docs.telerik.com/aspnet-core/knowledge-base/docker-build-nuget

But when running the docker build command there is this error

"error NU1301: Unable to load the service index for source https://nuget.telerik.com/v3/index.json."

What is wrong ?

Best regards.

My app showed no icons after upgrading to 4.6.0. :(

I tried the KB suggestions to fix it. Went from no icons to getting the hamburger back and blank boxes!

See:

In _Host.cshtml I added:

<link href="_content/Telerik.UI.for.Blazor/css/kendo-font-icons/font-icons.css" rel="stylesheet" />

In _Imports.razor I added:

@using Telerik.FontIcons

In codebehind page I have:

 public TelerikDrawer<DrawerItem> Drawer { get; set; }
 public DrawerItem SelectedItem { get; set; }
 public IEnumerable<DrawerItem> Data { get; set; } =
     new List<DrawerItem>
             {
     new DrawerItem
     {
         Title = "Home",
         Text = "Home",
         Icon = "home",
         Url="./"
     },
     new DrawerItem { Separator = true},
     new DrawerItem
     {
         Title = "CostTN Search",
         Text = "CostTN Search",
         Icon = "eye",
         Url="TNSearch"
     },
     new DrawerItem
     {
         Title = "RevIOTN Search",
         Text = "RevIOTN Search",
         Icon = "search",
         Url="RevIOTNSearch"
     },
     new DrawerItem
     {
         Title = "TN Mapping",
         Text = "TN Mapping",
         Icon = "subreport",
         Url="TNMapping"
     },
     new DrawerItem
     {
         Title = "Load Stats",
         Text = "Load Stats",
         Icon = "subreport",
         Url="LoadStats"
     },
     new DrawerItem
     {
         Title = "UnMapped Lines",
         Text = "UnMapped Lines",
         Icon = "subreport",
         Url="UnMappedLines"
     },
     new DrawerItem { Separator = true},
         // new DrawerItem
         //{
         //    Title = "Crtls Demo",
         //    Text = "Crtls Demo",
         //    Icon = "subreport",
         //    Url="ControlsDemo"
         //},
                 };

I am not sure what I am missing.

I want to separate Wizard or Stepper into separate Blazor components.

Someone that can guide me how to separate the Wizard steps into different components? I struggle to make validation work and the step logic work with parameter or cascading value.

I cannot just follow Wizard Form Integration because I need more steps and my own UI in each step so my file will be too big.

I can only show the wizard right now with sending it from ""parent" to "child" but validation and step logic doesnt work.

Should i looking at Stepper instead of Wizard? or have someone an example?

TelerikWizard @bind-Value="@Value" OnFinish="@OnFinishHandler" >
            <WizardSteps>
                        <PersonalInformationTwo
                            applicationModel="@applicationModel"
                            personalInformationForm="@personalInformationForm"/>

I'm using the bootstrap theme with CSS static content.

<link rel="stylesheet" href="_content/Telerik.UI.for.Blazor/css/kendo-theme-bootstrap/all.css" />

I would like to change the theme to dark but I can't find the name of the bootstrap dark theme. Is it available for the static content CSS?

If I use the CDN it works fine with both normal and dark modes but I'd prefer to use the static content.

Greetings,

When adding the TelerikRootComponent to the MainLayout.razor, the App.razor is initialized multiple times.  If I remove the TelerikRootComponent, then App.razor is initialized once as expected.

The problem is within App.razor, we use the NavigationManager to navigate to a login endpoint when a user is not authorized.  The navigation now gets triggered multiple times before actually completing.  What change do I need to make in order to have the App.razor initialize once while still using TelerikRootComponent?

I followed the guide wrapping @Body with TelerikRootComponent and then tried creating the TelerikLayout which had the same result.  This is in a .NET 7 Blazor Server app.  Thanks in advance for the help.
