I am creating a wrapper over the TelerikNumericTextBox component so that it works with all numeric data types (such as int, decimal, double, etc). I have added custom parameters for the Min and Max, and if they are not explicitly set I would like them to default to T.MinValue and T.MaxValue respectively. 

Hi,

I am getting the following error message when trying to upgrade from 3.6.1 to 3.7.0. I tried multiple times without success.

===========================================================

An error occurred while running the wizard.

Error executing custom action Telerik.Blazor.VSX.Actions.MultiProjectUpdateMasterPageAction: System.InvalidOperationException: Sequence contains no matching element
   at System.Linq.Enumerable.First[TSource](IEnumerable`1 source, Func`2 predicate)

Thank you

After installing Telerik UI (for WPF and BLAZOR) - the Intellisense / Autocompleter stopped working in Visual Studio 2022 17.4.2

https://www.youtube.com/watch?v=6Fn5C726h4U

Enter and Tab no longer inserts the snippet. 

After uninstalling Telerik UI from Windows, the Intellisense / AutoCompleter started working again !

Hi,

Could it be possible to add an option to automatically add title property (containing text value) on every td?
We don't like 'multi-row' rows in a grid, so we use ellipsis with white-space no-wrap.. So it would be very useful to automatically add a title containing the text value of the cell (of course only for cells without a Template).
Otherwise we need to add a Template with a title to every column we already have, which is... 

Thanks in advance!

Greetings.

For God's sakes I've spent 20 minutes on your site trying to figure out how to download your demos. Every link takes me that USELESS TelererkUIForBlazorSetup.exe. Syncfusion my be the worst but at least you don't have to google something that should be so redundant it's everywhere.
I finally gave up and had to google it to find it on Github. Absolutely worst experience ever.

Team,

Currently I am using Telerik UI Blazor with 3.7.0 version, few cases and intermittently TooltipShowEvent.Click is not working and tooltip is not getting displayed and unable to find root cause for it.

Could you please assist what is causing for this behaviour and feasible solution?

Below is sample code snippet where we use 3 tabs

<TelerikTabStrip Class="tmGraphTabStrip" ActiveTabIndex="@ActiveTab" ActiveTabIndexChanged="@ActiveTabChanged" @ref="@TabRef">
@for (var i = 0; i < 4; i++)
 {
<TabStripTab Title="@TabName" Class="tmTabHeaderCellStyle">
<TelerikGridLayout RowSpacing="20px" ColumnSpacing="1px" Class="grid-CardlayoutNew">
@*
display data in gridlayout structure for each row/column along with tooltip, we are able to see div selector and target selector Ids from Dev Tools browser
*@
</TelerikGridLayout>
</TabStripTab>
}
</TelerikTabStrip>

Ex:

<TelerikTooltip TargetSelector="@ToolTipCurselector" ShowOn="@TooltipShowEvent.Click" Position="TooltipPosition.Top">
</TelerikTooltip>

We'd like to track the community demand for using the Telerik Blazor components as Custom Elements.

Please share example common scenarios for such usage and list the components you want to register as Custom Elements to use in other SPA frameworks such as Angular or React.

I was wondering if the component can filter rows by searching in more than one column.

While using Safari browser, I am getting following exception message:

Hello,

Having one textbox and one label would be great. Please consider it.

After upgrading to Telerik Version 3.6.1 my CSS is messed up on my grids, the pagers look like the image below.

I would like to be able to set the Id on any Blazor component for automated testing purposes.

ADMIN EDIT

If you need something different than automated testing selectors, please add your use case in the comments.

For automated testing, you can cascade selectors through a parent element (e.g., a div or span) that has the desired attributes (be that id, class, some data-* attribute, etc.). Adding ID parameters to Blazor components can easily make them brittle because they can be repeated and included in arbitrary hierarchy easily - that's the core concept of a razor component - so such IDs need to be unique, which defeats the predictability you will need for testing.

If you are interested in testing with Selenium, you may find useful this request: https://feedback.telerik.com/blazor/1513117-translators-for-selenium-testing-for-the-telerik-ui-for-blazor-components. If so, Vote for it and Follow it so we can know there is interest, and so you can get status updates.

Installation of trial Blazor UI broke Visual Studio 2022 extensions. Cannot create Telerik Blazor project. Cannot open VS Blazor projects.

   So what I propose is a fixed width for a column of the grid (and locked) with the remaining columns auto-sizing.

In my situation, I have an action switch button where the client can delete a row, edit a row etc but the action code dropdown column needs to ALWAYS be the same width.  The rest of the columns should automatically size based on the existing behaviour.

   Now I have tried using the autosize for just that column, but I have to render the grid first, then run the autosize (which gives a fun show of resizing to the user) then all the columns become fixed width, but the vertical scroll bar doesn't move and stays in its initial position.

 

 

Can the dev team comment on any known reasons why Charts (I think both SVG and Canvas) might not display when a blazor page is rendered from an automation tool like Chromium, Puppeteer, etc.? (e.g., https://developers.google.com/web/tools/puppeteer).

I have a standard blazor page that I can manually from a standard Chrome window, and it works fine and the Telerik chart displays.

But the same page, when launched either headless or with a GUI browser window, from a tool like Chromium or Puppeteer (with javascript enabled of course), it seems like the DOM is never dynamically updated to include the chart.

Hi, we are using a tile layout for charts and are having an issue where the tooltips for the second row of tiles are appearing at the bottom of the screen away from the chart or not at all. Then when we scroll back to the first row of tiles the tool tips are out of alignment as well. The following screen shot shows an example.

 

We have a component that has a tab strip and the tile layout with the following code

And then a chart component that renders the individual charts with a tooltip

Textarea size is currently not easily controllable when using TelerikTextArea. My request for the size attribute was declined, as it was mentioned that rows and cols could be used with text areas - but TelerikTextArea doesn't expose these and I believe they should be easy to add support for, to pass through to the rendered textarea.
