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.
Please add the option for the Multiselect to filter the same way the DropDownList does. It's very odd & confusing for end users (and bad UX) in a UI toolkit for similar controls to do things in different ways. Can you please add the ability for the Multiselect control to filter items in the popup window the same way the DropDownList does with the nice filter text box.
Are you thinking about developing an app builder for Blazor to create a project and add telerik component and finally export it as Blazor app (server or wasm)?
(like this one develop from Infragistics https://appbuilder.indigo.design/app/)
This tool export every single page as razor page.
I often have the scenario where I need to switch from the autogenerated formitem to a templated version. Mostly because I need a different editor
<FormItem Field="@nameof(KeyValuesViewModel.Workplace)" LabelText="Workplace" EditorType="@FormEditorType.TextBox"/>
I create something like this:
<FormItem> <Template> <label for="WorkplaceInput">Workplace</label> <TelerikMaskedTextBox Id="WorkplaceInput" Mask="aa aaaaaa" Enabled=@WorkplaceEnabled OnChange="OnWorkplaceChanged" @ref=@WorkplaceTextBoxRef /> <TelerikValidationMessage For="@(() => KeyValuesViewModel.Workplace)" /> </Template> </FormItem>
It would speed up things if I just could use the "light bulb" and convert it. Instead coding it manually, copy, paste, edit the copied version. Over and over again.
Grid with columns price1 and price2. Enter value in price1, switch to price2, enter value there, and editor is set to old value after async events finish.
The value entered in price2 is correctly set to the property, but the editor reverts to the previous value. If you escape edit mode of the cell, the value entered before the events finish will be shown.
On (fast) tabbing and entering values, this removes the first values entered before the async background events finish.
I tried reproducing the problem in REPL, but could not get the exact same behaviour. In our case no specific value is being set to price2, it just reverts.
How would you approach preventing the editor from being overridden by other cells' delayed events?
Filter option switch back to default option (Contains) after entering value in the textbox.
- screenshot-1 - Select from filter option - Startswith ; Then, enter value in text box.
- screenshot -2 - After user enter first character , atomically filter option switch back to Contains (from startswith).
I really like the ability to drag and drop between controls. I though feel very limited, by Telerik enforcing both controls to have the same underlying data model (or interface) as per this article.
What would really be great, if the "OnRowDrop" event could accept other data models. I have no particular view on how exactly this should be implemented. It should work for server and WASM environments.
An example could be, that the "dragged" row is of type object and not <TItem> and it is left to implementation code deal with different data models being dropped on the control.
//Something like this
private void OnRowDropHandler(GridRowDropEventArgs args)
if(args.Item is IParentSampleData)
else if (args.Item is SomeOtherModel)
//Whatever is needed...
When I click on any item from the SplitButton dropdown list, it closes, until I release the key
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.
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.

After installing Telerik UI (for WPF and BLAZOR) - the Intellisense / Autocompleter stopped working in Visual Studio 2022 17.4.2
Enter and Tab no longer inserts the snippet.
After uninstalling Telerik UI from Windows, the Intellisense / AutoCompleter started working again !
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!
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.
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
<TelerikTooltip TargetSelector="@ToolTipCurselector" ShowOn="@TooltipShowEvent.Click" Position="TooltipPosition.Top">
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.
