I would like to see a thumbnail of the image in the FileManager for images. Currently it shows an icon for images. In place of the image icon I would like to see a small thumbnail of the image.
can we have the same functionalities as the AJAX html editor?
There are a number of controls missing from the new editor that was not in the old telerik editor. including Add spell check, cut, copy and paste {several options}, undo, redo, new paragraph, horizontal rules, insert time, insert symbol. Anyway to bring those functionalities into ASP.net core?
Hi guys,
I found out, that the QueryableExtension always generates a ToLower for strings filtered with the equals operator. The ToLower is applied by the FilterOperatorExtensions in this method:
private static Expression GenerateEqual(
Expression left,
Expression right,
bool liftMemberAccess)
{
if (left.Type == typeof (string))
{
left = FilterOperatorExtensions.GenerateToLowerCall(left, liftMemberAccess);
right = FilterOperatorExtensions.GenerateToLowerCall(right, liftMemberAccess);
}
return (Expression) Expression.Equal(left, right);
}It would be nice, if the to lower is controllable with a parameter. At the moment it generates a to lower in the sql query, which generates a lot of overhead in some situations with large tables.
At the moment I remove all "equal to" filter and apply it manually to the IQueryable object.
Best regards

I was wanting to create a multiselect filter inside the kendo grid that will filter an array column, NOT a simple string column. Just adding the .Filterable(ftb => ftb.Multi(true)) does display a basic 'multiselect' with just checkboxes in it, which is not ideal , but does work. But, when you click filter, the grid becomes empty. I had to use a clienttemplate() function, to return an html object like so:
export function MultiRowTemplate(data) { if (data == null) { return ""; } var row = ""; for (var i = 0, len = data.length; i < len; i++) { row += data[i].Description + "<br/>"; } return row; }
My column is:
columns.ForeignKey(a => a.DisplayExp, (System.Collections.IEnumerable)ViewData["Exp"], "Id", "Description").ClientTemplate("#= MultiRowTemplate(data.DisplayExp) #").Filterable(ftb => ftb.Multi(true)).Title("Experience");
the code for the foreign key doesn't make much sense as it's an array column, but that was pointed to by telerik support on other forum posts.
So, there must be a way to hook into that column and run some custom code to return to the grid the filtered values? i've seen examples for jquery, and mvc, but theres nothing for .net core. This should just work out of the box, as I don't think this is an uncommon need. Could you give me an example or point me in the right direction?
I'm trying to use it for navigation in a section using Razor Pages. Having to expand using javascript is very distracting when the user goes from page to page. Below is the code to create a self-running page that demonstrates the issue:
@page

Layout = null;

It would be useful to have an exemple of how to uploda directly to an Azure Storage container from a Kendo UI upload or FileManager component.
I'd like DateOnly support to be introduced to Telerik UI for ASP.NET Core because my Grid uses that type and issues occur in the Grid's PopUp and InLine editing fields that are bound to DateOnly fields.
Hey,
It would be very useful if the TimePicker component would have a feature called something like "AutoFocusTime()". By default, when there is no value inside the TimePicker, the default focused time is "12:00 am", therefore the user has to scroll up all the way to the required time. With the feature above, it would be possible to enter a time which should be focused by default. For example "8:00 am" which is when most businesses start operating.
Now the question is, why not just putting in a default value. Well, in a form with lots of inputs, the user may not know anymore which values he entered and which inputs have a default value set and therefore submitting wrong data. If a input doesn't have a default value this mistake can be caught by setting a [Required] attribute. Threfore, the user has to enter a value and it will be guaranteed that all values where entered by him and it wasn't a default value which has been set.
See ticket id 1412837.
Currently, the new feature .ComponentType('modern') does NOT respect the .Interval(n) setting for the control.
Demo of ComponentType setting on DateTimePicker control
According to the API Reference the Interval setting, Interval
"Specifies the interval, between values in the popup list, in minutes."
The ComponentType('classic') does respect the Interval setting. Thus, the ComponentType feature should be updated to respect the Interval setting when the "modern" ComponentType is selected. The time interval under modern is always 1 minute (see screenshot).
@(Html.Kendo().DateTimePicker()
.Name("SessionEndDateTime")
.Interval(15)
.ComponentType("modern")
.Events(e => { e.Change("onSessionEndChange"); })
.HtmlAttributes(new { style = "width: 100%", title = "Session End Date/Time", @class = "form-control" })
.DateInput()
)
Modern should respect the Interval setting for the control.
Currently, if a PDFViewer is opened on a mobile device and we use two fingers to zoom its content, the file is zoomed but the more we zoom it, the blurrier its content becomes. The reason for this is the fact that when we use "pinch-zoom" to zoom the PDF file(in a PDFViewer) it is zoomed using the browser's zoom functionality and not the functionality provided by the PDFViewer component.
It will be a very useful feature if the built-in PDFViewer zoom functionality is used when the user zooms content with two fingers, on a mobile device
When trying to install Microsoft.VisualStudio.Web.CodeGeneration.Design 7.0.4 NuGet package in a Telerik UI for ASP.NET Core 2022.3.1109 application, it throws an exception:
NU1107: Version conflict detected for Microsoft.CodeAnalysis.CSharp.Workspaces. Install/reference Microsoft.CodeAnalysis.CSharp.Workspaces 4.4.0 directly to
project TelerikAspNetCoreApp3 to resolve this issue.
### Reproduction of the problem
1) Create a Telerik UI for ASP.NET Core 2022.3.1109 application (.NET 7.0).
2) Install Microsoft.VisualStudio.Web.CodeGeneration.Design NuGet package (version 7.0.4).
3) Review the NuGet Error in the output.
### Workaround
Install the the following NuGet packages:
- Microsoft.CodeAnalysis.Common
- Microsoft.CodeAnalysis.Workspaces.Common
- Microsoft.CodeAnalysis.CSharp
- Microsoft.CodeAnalysis.CSharp.Workspaces
- Microsoft.CodeAnalysis.VisualBasic
- Microsoft.CodeAnalysis.VisualBasic.Workspaces
Alternatively, install an older version of the Microsoft.VisualStudio.Web.CodeGeneration.Design package.
### Environment
* **Telerik UI for ASP.NET Core version: 2022.3.1109
* **.NET version: 7
Hallo Teleirk team
Please add Rotate function to the imageeditor
Thank you

I noticed that in version 2023.2.606 you introduced some Date Editing enhancements for the DateInput component, like:
but these options aren't available for other DatePickers that implement the DateInput internally:
@(Html.Kendo().DateTimePicker()
.Name("datepicker")
.DateInput()
)
Provide support for the asp-page-handler attribute to call a handler in an ASP.NET Core 2.1 Razor page in addition to supporting controller/action methods.
We want to have a tabstrip that a user can select the tabs that he wants with checkbox. For example:
It will be a great feature.
<div id="tabstrip">
<ul>
<li>@Html.Checkbox("name",false) A </li>
</ul>
</div>
