The filter list item menu defined as follows do not have accessible name.  Please provide work around or fix that I can implement.

                            <TelerikGrid Data="@ViewModel.RouterAndDataLossInformation" TItem="TrafficLossSummary"
                                                        Pageable="true" 
                                                        Sortable="true" 
                                                        Groupable="false"
                                                        FilterMode="Telerik.Blazor.GridFilterMode.FilterRow"
                                                        Resizable="true" 
                                                        Reorderable="true"
                                                        Height = "100%">

I have a TelerikGrid that I set the filter state using the OnStateInit method. This work fine and the menu item shows up blue to indicate that it is in use, but when I choose that column menu and the Filter option an unhandled exception occurs.

I have produced a demo and been able to reproduce the issue, located here - https://blazorrepl.telerik.com/wcYDwFbw26v6wIqr52

I'm guessing that there is some setup missing, but from reading the documentation, I can't seem to find it.

Can't find css class for hide this border
Border displayed after click on tab content.

Hi.

I want to use the TelerikPanelBar with two different Datasources. For the Header, I have a List "Articles" and for the Content I have an object "ArticleDetails", that will be loaded "lazy" if someone opens the accordion.

I want to use also the HeaderTemplate and ContentTemplate Feature.

The Samples show only PanelBarItem within a list of PanelBarItems, but I need a total different Object in the Content Area. The Idea is to load a list of Articles, and then when a user clicks on a panel the Details of the Article will be loaded and displayed.

Thanks and Regards

After updating to v3.6 I copied your demo code from here and pasted it into my blazor wasm project and I'm getting the error below. What do I need to do to resolve this?

Unhandled exception rendering component: Could not find 'TelerikBlazor.initPdfViewer' ('initPdfViewer' was undefined).

Hello,

I need a custom sorting method for the TelerikGrid. So according to the docs, I have to use the OnRead Event. Is there a way not the implement all filtering by myself and can I use the Telerik Filtering with the OnRead and only implement my custom sorting?

Thanks

Holger

In my code I'm setting the ExpandedItems and SelectedItems (single item). I have my TreeView in a scrollable div. Once the TreeView has expanded, I want to scroll the selection into view. In javascript I'm getting the DOM element with the aria-selected="true" tag and calling "scrollIntoView". 

The problem is, that tag doesn't exist until after the TreeView has expanded.  There doesn't seem to be any event tied to after the TreeView has expanded. At the OnAfterRenderAsync event, the TreeView hasn't expanded yet.

I can invoke the javascript with a button and it works fine - once the TreeView has expanded. But, I don't want the user to have to click a button to view the selection. Is there a better way to do this?

I would like to use this control but I am not getting very far. Sad!

The loading does not appear! and my app looks like tis doing nothing for a minute or so.

Then the grid with the data appears.

HOw do I set this up to have the loader appear before the data is done and then disappear when the grid is done?

My razor page looks like this:
