So, brand new machine (Win 11 pro 64bit), brand new install of Visual Studio & Telerik, use the Telerik templates to create a new Blazor Server project.
When I run the application (with changes or first run), it takes almost a minute to start the application.
Without changes it starts in 2 seconds.
The fix is to add the following to the application's csproj file.
<PropertyGroup> <UseRazorBuildServer>false</UseRazorBuildServer> </PropertyGroup>
After the fix, it takes an just a little longer to run than without changes. Since I have not heard back on my support ticket, I wanted to report this as a bug so hopefully it can get upvoted and we can get an answer to this issue.

Similar problem with my new laptop which is about 50% slower but exactly the same issue.
Hi Telerik Support.
I am using TelerikComboBox with Virtualization and enabled Filtering. If I filter for a text and then scroll down, the filter text gets cleared. I am using OnRead event to populate the combo box. But the same issue is seen with local data population in the below sample code.
I need to show the user the text they have entered even when they scroll down to the next page. Is there a solution for this?
It would be VERY helpful if you integrated "Prevent the Grid from wrapping text in multiple lines and show ellipsis" into grid as an option (so we would not have to write separate code and style).
I think this is one of the most needed features since grids almost always have data that wraps line.
I have a ComboBox that gets data from a remote service, using virtualization. When the PageSize property is big enough (in my case 20), I have issues scrolling down. I'm trying to scroll but it removes the input text.
You can use your own demo examples to replicate this issue. To reproduce the issue, try the ComboBox - Virtualization, in Telerik REPL (Demo).
When using the OnRead event of the ComboBox there is no way to retrieve the selectedItem because the list of items that is populated is internal.
There are 2 workaround but they are not ideal:
- Saving the list of items returned by the OnRead event into a parallel list and then retrieve the selectedItem from it -> the problem is that there will be 2 identical lists in memory and, if scaled, might cause problems:
CachedSitesList = result.Items; args.Data = result.Items; args.Total = (int)result.TotalCount;
- Retrieving the selectedItem by calling the DB using the Id of the item -> the problem is that it's one more request to add to the DB and the performance is going to decrease if scaled, also it seems useless as the item is already present in memory.
We suggest adding a function to return the selectedItem to improve performance and scalability of the component.
We are looking to port an angularjs web application to Blazor and I didn't see the diagram component similar to the one found in Kendo UI. It would be nice to see a viso-like component in UI for Blazor.
Since upgrading from 3.8 to 4.4 (including all new css) created dialogs from DialogFactory are sometimes behind an already opened modal window.
The reason for this seems to be an incorrectly, automatically calculated z-index of 10003 when the open dialog has 10006.
This does not always happen, there are scenarios where the first created dialog works fine, and the next called in the same method suddenly is behind the dialog, thus the error seems to be in telerik and not our side.
We could not yet find a proper workaround apart from creating custom dialogs.
Create a word style component.
Currently my wpf desktop app uses a editor style component and refreshes a crystal reports window component to show edits made to a pre created document. We use this to create quote letters using custom legal jargon.
I am in the process of moving that program to Blazor. A word component that i can wrap our custom texts around and buttons in the title bar for pasting our prefomatted text would be so much better than our current setup.
Could this be added to the roadmap?
Hi Support Team,
in our project we are using Telerik Chart and has required to update theme of chart from dark to light and light to dark.
telerik chart in child razor page and dark/light button in mainlayout.razor file but telerik chart updating theme when click on button exist telerik chart razor page. as below link it is an existing issue.
please advice how to resolve the issue.
When I use TelerikDatePicker in my own component and the I use this component in Form, the validation for this input on the UI side doesn't work. The k-invalid class is not added, the appriopriate aria-invalid value is not set. The value on the TelerikDataPicker CascadedEditContext side is ok, an error message for this field appears after validation.
This kind of behavior causes duplicate OnRead calls for the same range. If the OnRead method invokes a request to the API it will result in duplicate requests with the same range.
When you edit in Telerik Repl, you get a warning message:
What was weird though, is when I ran it from directly from the link in the documentation, I didn't get an error. I made one small change to the code (swapped line 54 and 55 (just seeing if I could change the rendering order, which I can) and then I saw this warning. But any change to the code generates the warning.
When you click "Preview" under Using TelerikFontIcon, the preview is blank, even if I scroll to the top, still nothing.
The Theme Builder contains a really nice looking Popover control, and I was a bit disappointed to discover that this doesn't seem to be documented or supported in UI for Blazor.
I realize I can probably use the Tooltip to achieve a similar effect, with two caveats:
Is there any chance a Popover control is planned for a future release?
During grid initialization I have duplicate OnReadMethod call. I dynmaically set LoadGroupsOnDemand parameter. When LoadGroupsOnDemand is false and when I skip the second call (I shouldn't do any extra logic to calculate the call number anyway) it works fine. If LoadGroupsOnDemand is true I have to call it twice. With early ending of first call, second OnRender call won't be done. If I do "return" at the begining of second call it returns me an empty grid.
Similar issue to this one: https://feedback.telerik.com/blazor/1442276-onread-called-twice-on-initialization
I would like to be able to set the aria-required or the required HTML attribute to the input components in the Telerik UI for Blazor suite. This is needed because currently, the screen readers do not notify the users of the application that an input is required.
I would like to use the new structs that are part of .NET6 - the DateOnly and TimeOnly.
Their support should extend to all respective date and time pickers and more complex components like the Grid, Gantt, Scheduler, and other applicable components.
