I want to prevent users without WriteAccess to see the GridCommandColumn and a custom GridColumn containing some buttons.

Those two columns are the first in my grid.

If I add AuthorizeView tags like this

<AuthorizeView Policy="MyPolicy">

   <GridCommandColumn ...>

      ...

   </GridCommandColumn>

</AuthorizeView>

<AuthorizeView Policy="MyPolicy">

   <GridColumn ...>

      ...

   </GridColumn>

</AuthorizeView>

they will be hidden if the user does not comply to the policy but if he does comply the columns are displayed not as the first columns in the grid but as the last.

As a workaround I now don't hide the columns but their content (by moving the AuthorizeView tags inside the column tags).  This is not a good solution though since I loose valuable horizontal screen-space for displaying empty columns.

In many cases in a grid you may have additional data that the user can view however you don't want to show it as a default.

In these cases it would be nice to create the column normally, set the visible="false", and then have a built in column chooser feature.
This chooser would be a simple popup with a list of columns where the user can check whether visible or not.

Hi there,

i'm struggling with kendo theming. I'm trying to implement a material ui with telerik ui for blazor. I did follow the steps in the getting started pages but i'm getting a half baked ui which is missing essential parts like the focus animations for textboxes like shown in the textbox demo: https://demos.telerik.com/blazor-ui/textbox/overview.

My recent approach was to compile the files in the kendo theme Git repository but these also don't work.

What am i doing wrong? How exactly did you achieve the full material experience in the demos?

So lonG

Daniel

When you have LazyLoading() enabled on an EF context, the grid throws errors similar to

 

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.NotImplementedException: This is a DynamicProxy2 error: The interceptor attempted to 'Proceed' for method 'Void set_LazyLoader(Microsoft.EntityFrameworkCore.Infrastructure.ILazyLoader)' which has no target. 

 

Here is a sample of the service registration that causes the issue

 

            services.AddDbContext<ApplicationDbContext>(options =>
            options
            .UseLazyLoadingProxies() // this causes the problem
            .UseSqlServer(Configuration.GetConnectionString("DefaultConnection")), ServiceLifetime.Transient);

Hi,

Any information on when the Layout Components available in AspNetCore will be available in Blazor?

I am currently putting a proposal together to purchase Telerik for Blazor and could really use some of those components to enhance the application than relying on 3rd-Party integrations.

Hi!

 

I want to create a grid with multiselect options (controlled by checkboxes in the first column). I have used code from https://demos.telerik.com/blazor-ui/grid/selection but when i try this code in my project there are no checkboxes in the first column, just empty cells. Am i the only one with this problem?

Hello Team;
I'd like to make a suggestion.

When one of the third party vendors became involved in producing Blazor components, they opted to wrap their existing 65+ JS components as "Blazor" components. At first, I though that's not as good as Native components that Telerik is doing.

But, as I then read more about their plan, they basically offered a full solutions from their JS library to developers, so we, the developers can start building a complete business application and as long as the vendor doesn't change the Wrapper API and only change the back end, their changes should work on the developer side.
Their idea was, to give us a jump start with JS and we start using counterpart Native Blazor components, and as as they become available, the components get changed to Native Blazor, and the apps written by us continue working.
I think this is a great strategy to have the full suite available to us from start to build apps than waiting for each Native component to be build.

My suggestion is to do the same, i.e. the word processing component where it is needed and we can build our app using the JS Word processor and by the time we are ready, Telerik might have the Word processor replaced by Native Blazor. This way we can build our apps with a full suite from the start than waiting for essential components to be built.

I hope the team would consider such strategy if possible.
Thanks!

..Ben

Hi!

I'm trying out Marin Bratnov's code (from a Link - demonstration code). When i try to write a letter in a TelerikComboBox control it is automatically cleared out. I get the same behavior in my own project too. Filtering TelerikComboBox outside the grid works perfecly. Please check te video.

I am very surprised that Multiselect is missing among the list of Blazor controls being offer.  Syncfusion already offers a full-feature Multiselect.  Is a Multiselect on the road map?  When should we expect it.  Currently the only way to have a select list with multiple selections enabled is a pretty ugly JSInterop hack.  I am honestly considering switching to Syncfusion as they seemed to be far ahead of Telerik in Blazor development.

It seems like Blazor on the server-side will be re-branded as Razor Components. Will Telerik support it?

I have a TelerikComboBox in an EditorTemplate within a Grid. Code looks like this:


                   <TelerikComboBox Data="@CustomerPayCodes"
                                                     @bind-Value="@PayItemMapInEdit.ClientPayCode.UniqueId"
                                                     Placeholder="Select..."
                                                     Filterable="true"
                                                     TextField="PayCodeDisplayName"
                                                     ValueField="UniqueId"
                                                     @ref="_clientPayCodeComboBox"
                                                     Width="auto"
                                                     Enabled="@(string.IsNullOrEmpty(_payItemTextBoxRef?.Value))">
                                    </TelerikComboBox>

 

Where reference prop looks like this:

 

    private TelerikComboBox<PayCode, Guid> _clientPayCodeComboBox;

 

When adding a new row, the Placeholder text becomes the empty GUID, until I click in the box and then outside, upon it changes to correct "Select...". The GUID is never supposed to be showed at all in the box, that is only the binded value.

 

See attached pictures.

 

Please advice.

 

Br,

Sten
