I have a grid with in-cell editing.  Only some of the columns are editable. 

The grid is grouped by two columns, which I default in OnGridStateInit.  The two aggregate columns are NOT editable.

Everything works just fine, but as I click around through the editable columns, the page gets slower and slower and slower over time.  Specifically, clicking away from an editable column causes a refresh (or something) that takes increasing longer and longer.  A spinny loader appears.

This behavior immediately goes away when the grouped columns are removed by ungrouping at the top of the grid (no code update).

Is this a bug or am I doing something wrong?

I tried changing from in-cell editing to in-row editing and have the same problem.

A workaround is to ungroup for editing, and then regroup for display purposes, but I'm new and want to verify I'm not doing something wrong.

My bosses like the idea of being able to add the annotations on the PDF Viewer.  I pull my files from Azure and they want to mark them up.  So, I'll need to save the updated copy back to Azure.  How does this work?  Do you have an example of how to keep the changes?  Do the annotations become part of the PDF File or must I save those off separately in order to reapply them when I view?  Or, can I just take the modified bytes and upload them as a new copy of the original file?

I am new to using the UI for Blazor products.  I added the code from https://www.telerik.com/blazor-ui/documentation/components/tabstrip/overview

The control renders but I am not able to select the 3d tab, the control remains on the first tab.  Any help on why would be appreciated.

Here is the code from the razor page.

Hi,

 is there any way, how to "debounce" when you scroll down for example by 1px to NOT CALL onread when data is already in current dataset?

Why? Because you are scrolling to item, which is already loaded(just presented invisible down in html markup).

expected:

- if you scroll to "end of the current page dataset" then it should read next one - call OnRead.

Simple calc - example:
PageSize = 100 - just for testing
ItemHeight= 400px  - HUGE ONE, to get the idea
GridHeight = 600px
items on "page/screen" ~ 2, items loaded: 100

So you at least have inmemory 45 "pages" of data. So calling OnRead is not necessary.

Here is example to observere how many times OnRead is called So if it will be sql/external/network data paging, it hits DB +api every single pixel of move.

if someone thinks about caching it to the local variable, dont do that :)  = if even so, is there a way how to get it from <TelerikGrid @Ref=ME  .../> @Me.Data ? If not, so caching this way is bad idea. 

Thanks for the tips.

Hello everyone,
Is there a way to get access to the group names at the cell level of a PivotGrid?

The PivotGridDataCellTemplateContext has internal IGroup properties that would fit my need, but those are internals.
Is there of way to access/stored them or any work arounds?

My goal would be to generate a cell "onclick=@() =>MyMethod(Group1, Group2)" event that would pass those informations to a method.
Ultimatly, the method would filter a List/Grid under the PivotGrid.

Thank you very much

Hi!

I'm doing a migration from a WPF application to Blazor and I would like to know if there is a way to make a column of a grid reusable. Example:

In WPF you can have a resource dictionary and reference it from the component in question to represent data with the same UI, in Blazor I think this is not possible, the only thing I can think of is to componentize the columns but I'm not sure if this is the right way to do it. Is there any contemplated or recommended way?

Thanks in advance!

Telerik WPF - CellTemplate

I have a Scheduler on a dialog with a radio button group. Selecting radio button displays a number of appointments in the calendar and the Scheduler allows the user to click one to select it. When they select another radio button, I have it retrieving a new list of appointments and they're rendered properly but the same slot is still selected. If that slot isn't in the list, it selects a different (I think based on the previously selected appointment's index).

How can I clear the selected appointment index completely?

Is there a way to add a stylesheet to the prosemirror in the iframe?

I want to add a plugin for a Placeholder eg:

https://gist.github.com/amk221/1f9657e92e003a3725aaa4cf86a07cc0

Also: is there a way to let the user change the height of the TelerikEditor, just like with a text area (bottom right corner)?

I'm getting a JavaScript error when I open a TelerikDialog that has a TelerikScheduler in it. The error is:

telerik-blazor.js:1 Uncaught TypeError: Cannot read properties of undefined (reading 'filter')
    at m.handleOverflowingItems (telerik-blazor.js:1:2451674)
    at e.ResizeService.onResize [as resizeCallback] (telerik-blazor.js:1:2446927)
    at ResizeObserver.onResize (telerik-blazor.js:1:2228100)
    at telerik-blazor.js:1:2239508

I have a reproduction here, specifically in this page. The error appears when you click the button and the dialog opens. If I remove the Scheduler, the error goes away. The configuration for the Scheduler was taken from the overview page.

This is happening with Telerik Blazor 8.0. I checked with version 6.2 and it didn't show an error in that case.

Code

        <FormItem Field="@nameof(NewRecordClaim.EvidenceLink)"  Id="EvId" LabelText="Evidence Link" Enabled="false">
                    <Template>
                        <label for="EvidenceLink" class="k-label k-form-label">Link:</label>
                        <div class="k-form-field-wrap">
                            <a target="_blank" href="@MyModel.EvidenceLink">View evidence at @MyModel.EvidenceLink</a>
                        </div>
                    </Template>
                </FormItem>

MyModel.EvidenceLink is for example
