It stops working if you open it too fast. It goes into a state where no matter what you do (Rebind/changing data bound values etc.), it will not open and show items.
It can be reproduced easily by calling .Open() in OnInitializedAsync()
I have reproduced it without MS Playwright in REPL, so you can easily debug it.
https://blazorrepl.telerik.com/QIOUYoPc57iQKy6702
If you uncomment the await Task.Delay(3000); the code will work.
Expected behavior:
It is ok that Open() does nothing while the control is initializing. It is not ok that just because you called Open() once, then you are forever stuck without being able to open it later, no matter how long you wait or what you do with the items.
I do not want to insert random Delays in my code either as I expect the TelerikDropDownList to not malfunction just because I open it too early.
I hope you can prioritize this as right now the DropDownList is not usable for us.
I have a scenario in which we have user definable columns for a grid, including hundreds if not thousands that need to be ported from the old version of our product. This means these column keys would be strings that may contain spaces or even special characters - and as such cannot be a valid C# property name (which means using an ExpandoObject approach will not work)
It would be really beneficial if the TelerikGrid component could be given Data of an IEnumerable<Dictionary<string, object>> where the Field property of GridColumn (or a new property) would line up with a key in that dictionary rather than a field name for the component to then use reflection with.
A customer with multiple modules of our product installed may very well have columns with similar names, i.e "Some Key", "SomeKey", "Some_Key", "Some & Key" - so simply replacing spaces or special characters may not always still give unique keys.
Please provide item templates for the file list, similar to:
- https://www.telerik.com/kendo-angular-ui/components/uploads/upload/templates/
- https://demos.telerik.com/kendo-ui/upload/templates
Support the recurrence rule to create multiple appointments per time slot. Examples of such rules are:
FREQ=DAILY;BYDAY=MO,TU,WE,TH,FR,SA,SU;BYHOUR=08,09,10,11,12,13,14,15,16;BYMINUTE=50
The `Multiple` property is always set to `false` (see code below); one can drag & drop multiple files to the dropzone but only one is uploaded at a time.
Our customers won't accept this behavior as it makes uploads of multiple files very cumbersome. This "detail" makes the `TelerikFileManager` unsuitable for our application.
Please make the `Multiple` property configurable via the `FileManagerUploadSettings`.
(You may also want to consider making `AutoUpload` configurable while you're at it).
__builder2.OpenComponent<TelerikUpload>(266);
__builder2.AddAttribute(267, "AutoUpload", (object?)RuntimeHelpers.TypeCheck(value: true));
__builder2.AddAttribute(268, "SaveUrl", (object?)RuntimeHelpers.TypeCheck(UploadSettings.SaveUrl));
__builder2.AddAttribute(269, "SaveField", (object?)RuntimeHelpers.TypeCheck(UploadSettings.SaveField));
__builder2.AddAttribute(270, "RemoveUrl", (object?)RuntimeHelpers.TypeCheck(UploadSettings.RemoveUrl));
__builder2.AddAttribute(271, "RemoveField", (object?)RuntimeHelpers.TypeCheck(UploadSettings.RemoveField));
__builder2.AddAttribute(272, "WithCredentials", (object?)RuntimeHelpers.TypeCheck(UploadSettings.WithCredentials));
__builder2.AddAttribute(273, "Multiple", (object?)RuntimeHelpers.TypeCheck(value: false));
__builder2.AddAttribute(274, "AllowedExtensions", RuntimeHelpers.TypeCheck(UploadSettings.AllowedExtensions));
__builder2.AddAttribute(275, "MinFileSize", RuntimeHelpers.TypeCheck(UploadSettings.MinFileSize));
Hi,
Are you planning to add a loader to the grid in the feature?
E.g as an isLoading attribute or exepnd the build-in one?
With method OnRead to fetch data, when grid is not yet loaded with data, it displays no records available.
Also when chenging data, loading is not starting, but there is an unsmooth transition after some time.
Thanks in advance for your time, Kacper
Hi - this one is a feature request, not a bug. :)
For the filter menu, when you enter a filter value, it would be nice if you could press enter to execute the filter instead of having to click "Filter."
I want a less-persistent popup, where a click outside of its boundaries would close it. To give a real world example, the Share Snippet feature in REPL works in such a way.

Telerik edit: A workaround for the time being is to attach a JavaScript click handler that closes the Popup instance: https://blazorrepl.telerik.com/GyumGrEs22yZgoCD16
Hello,
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.
Thank you.
Code example:
Possible:
private List<DateTime> _disabledDates = new();
<TelerikDatePicker DisabledDates="_disabledDates">
Not Possible (Requested Feature)
private List<DateTime> _disabledDates = new();
<TelerikDateTimePicker DisabledDates="_disabledDates">
We would like to get the datetime picker to autofill the year when entering just two digits for the year with a format of dd-MM-yyyy HH:mm:ss.
So when you enter 23-04-25 it changes to 23-04-2025. Currently it changes it to 23-04-0025, which isn't our desired result.
Something along the lines of how this works: https://jsfiddle.net/anbdwL0h/ but then with a 4 year digit format as result.
On the Spreadsheet control please display a function list when the user types "=" or provide the user with some other reference about the available functions.
Hello,
Please consider a Grid feature that changes the component layout on mobile devices or narrow screens. The idea is to switch the column layout to a card layout or anything similar to this example: https://css-tricks.com/responsive-data-tables/
It is possible to implement a similar behavior with the Telerik Blazor Grid and MediaQuery components, but it requires reusing the column titles in the CSS code: https://blazorrepl.telerik.com/GnYPmHFR176Jg5Yg02

Telerik Blazor team: Everyone who is interested in this feature, please vote for it to help us prioritize. Also, share your opinion about which Grid features you strictly need in the "mobile" layout and which ones you are ready to sacrifice. Some features don't make sense in a card / listview layout anyway, but still, the mobile-friendly Grid may require completely different HTML markup and UX, so some features may need to be completely revamped.
