Currently I am using a Telerikform which has a FormItem. This FormItem is a Dropdownlist using templates.

The Form has an OnUpdate event I am listening to and the Dropdownlist has a ValueChanged event.

If I select an Item in the Dropdownlist the OnUpdate of the Form get triggered befire the ValueChanged on the DropDownlist.

Is this intended behaviour, if yes, how can I change the order?

Hi, i have a TelerikGrid who manage paging and read data using the OnRead property.

On top of my grid i have a button to open/hide the inline grid filter (binding a property with the FilterMode grid property).

Now the problem is: when i open o close the filter (changing the FilterMode property) the OnRead method is invoked.

I don't want to do a server request to read data if not necessary, and simply open or close the filter does not affect the data loaded in the current page of the grid.

how to avoid this?

This is a sample code to reply the issue:

My team has noticed a significant increase in build times for our Visual Studio 2022 solution since the 8.0 update. It got marginally better with 8.1.1 but still much slower than before. We have about 6 projects in the solution that reference the Telerik UI for Blazor libraries. Each of these projects appears to be doing its own license validation step. The step takes 5-10 seconds per project so adds 30-60 seconds to the build time. This wouldn't be that onerous, but this is done with every single build, even incremental builds. So the edit/compile/test cycle has gotten significantly slower, impacting productivity negatively.

Can something be done to make this less onerous? Maybe checking once per Visual Studio session? Once a day?

Hi,

I would like to confirm whether the following behavior is a known issue with the TelerikEditor component. Specifically, I am referring to its ValueChange event as documented on Blazor Editor Events - Telerik UI for Blazor.

Please, use the following code example instead:

@* Provide an initial value and update the view-model through the ValueChanged event *@

<TelerikEditor Value="@TheEditorContent" ValueChanged="@ValueChangedHandler">
</TelerikEditor>

@TheEditorContent

@code {
    string TheEditorContent { get; set; } = @"<div>
    <p>Paragraph 1</p>
    <p>Paragraph 2</p>
    <p>Paragraph 3</p>
    <p />
    <p />
    <p>Paragraph 4</p>
</div>";

    void ValueChangedHandler(string value)
    {
        // update the view-model
        //TheEditorContent = value;

        Console.WriteLine("ValueChanged fired");
    }
}

In this example, TheEditorContent string as been assigned a verbatim literal string containing CRLF formatting. The view-model update was commented out.

Compile and, hopefully, you'll confirm as I did that if you click or try to type on the editor, the console will infinitely loop over the ValueChangeHandler and print "ValueChanged fired" indefinitely. Furthermore, if you actually update the view-model, although the loop doesn't occur anymore, the ValueChanged event is fired upon cliking once on the editor. I assume that upon update, the editor changes the formatting of the input in such a way that this "bug" is not longer triggered on further clicks. Why does that happen and how can one fix it?

PS: I noticed this behaviour on my own project, where I wanted to save the original checksum of the text and compare it with successive new checksums as I edited the text in order to check for text differences. Anyway, due to this problem I have a different checksum as soon as I click the editor, thus triggering other logic of mine warning the user that it needs to save his/her changes (although there aren't any).

Hi,  I am creating E2E testing using Playwright , but I am having issues getting the value of the textearea.

As you can see on the screenshot below when using the playwright code generator it picks the label  "This project is unique because…" but I want the Value "test user 5.1"  , looking at he HTML generated the value "test user 5.1" is not there , how do I get the value ? 

I also tried using the data-testid tag on the components  but it wont work .

 <TelerikTextArea data-testid="test1" @bind-Value="@extendedData.UniqueBecause"
 MaxLength="1000"
 Rows="3">
 </TelerikTextArea>

What's the best recommendation to test using Playwright ? 

Thanks .

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.
