You may get an exception like

InvalidOperationException: The current thread is not associated with the Dispatcher. Use Invoke() or InvokeAsync() to switch execution to the Dispatcher when triggering rendering or modifying any state accessed during rendering.

or you may get components that simply don't work (for example, a Window does not show, a treeview does not expand).

The solution is to revert to the RenderComponentAsync method in your _Hosts.cshtml file.

When in edit mode the editable area width can be larger than the column width if column width is small, for example 100.

Using the new Grid grouping feature in 1.6, the Grouping button and the group header row both use the field name of the group column, rather than the title.  This is visible in the animated demo, where a column titled "On Vacation" becomes "IsOnLeave" once it is used as a group name.

I expect this is already known and slated to be fixed, but there aren't any grouping issues at all in the public tracker, so just in case...

At the moment only the DateInput has it and it is hardcoded for the pickers. I would like to be able to set it for the pickers as well

I'd love to see a file upload component similar to https://github.com/SteveSandersonMS/BlazorInputFile.  Just a wishlish item; not at a priority at all for us.

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.

One feature that is missing from the current set of Blazor UI components is a chips control. I'm not sure if it's OK to link to 3rd party controls, but this is a fairly common control that is available on multiple platforms. I can provide some samples if required.

Hello Team;

Is there plan to offer "Card" component where we can create a card with different parts and properties, i.e. Title, Sub-Title, Text, Image, Action buttons and etc.

Something like this:

https://vuetifyjs.com/en/components/cards/#grids

If my memory serves me right, I thought I had seen as part of 2021 R1 roadmap.

Thanks!

I'm currently migrating a project from ASP.NET MVC to ASP.NET MVC Core.

In the server code I'm using a DataTable from the database which is converted to a DataSourceResult with ToDataSourceResult.

It worked fine in the ASP.NET MVC version, but the same code in the ASP.NET MVC Core version throws an exception when using aggregate functions.

System.InvalidOperationException: 'No generic method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic. '

We are looking to update our application to Blazor but one of the controls that we use is the Filter Control ( from .Net Core controls).

Any chance a Blazor control can be created for this?

Release 2.21.0

1. Create tree model from class:


public class TreeNodeViewModel
{
    public string NodeName { get; set; }
    public IEnumerable<TreeNodeViewModel> Children { get; set; }
    public bool Expanded { get; set; }
    public string Color { get; set; }
    public string IconClass { get; set; }
}

2. Pass this tree for rendering to the component "TelerikTreeView".

3. An error comes out:

2020-12-03T09:44:15.312Z] Error: System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.)
 ---> System.NullReferenceException: Object reference not set to an instance of an object.

   at Telerik.Blazor.Components.Common.DataBoundComponent`1.ProcessDataAsync()
   at Telerik.Blazor.Components.TelerikTreeView.OnAfterRenderAsync(Boolean firstRender)
   --- End of inner exception stack trace ---

 

Note: This problem is due to the fact that there are no children in the last node of the tree and IEnumerable Children == NULL. Method "GetFlatItems" in version 2.18.0 it had a NULL check, in version 2.20.0 it is not.
