Currently, the only means to execute actions with the image editor is to use the built-in toolbar. While covering the most basic use cases, this approach limits the usage of the component in some more advanced scenarios. For this reason, it would be beneficial if some of the internals are exposed as a public API, to allow executing actions with the image editor programmatically.

I am opening this topic to collect customer feedback which features need better public exposure. When voting for a feature, please provide some details how do you intend to use it in your application, if possible, so that we can design a more intuitive and easy to use API facade for it.

TimePicker allows you to create custom Accept and Cancel commands, still, currently there isn't a way to bind a command parameter and then use it in the corresponding command Execute method.

On Samsung phones, the decimal separator and minus sign are in the same keyboard button and you press it once for the decimal sign to be written and press it twice for the minus sign to be written. After some tests, I found that this works fine on cultures that use "." as the decimal separator, but not on cultures that use "," (like Portuguese).

 

What happens is that no matter how many times you press the ", / -" button, it never writes the minus sign, therefore doesn't allow writing negative numbers.

Bar series disappear when applying zoom and then pan

The behavior can be reproduced in a horizontal bar series

The vertical axis is categorical, and the horizontal axis is numerical

<telerik:RadCartesianChart.ChartBehaviors>
                <telerik:ChartPanAndZoomBehavior PanMode="Vertical"
                                                 ZoomMode="Both" />
            </telerik:RadCartesianChart.ChartBehaviors>
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:CategoricalAxis />
            </telerik:RadCartesianChart.VerticalAxis>
                <telerik:RadCartesianChart.HorizontalAxis>
                    <telerik:NumericalAxis Minimum="0"
                                       ShowLabels="True"
                                       LabelFormat="N0">
                    </telerik:NumericalAxis>
                </telerik:RadCartesianChart.HorizontalAxis>
                <telerik:RadCartesianChart.Series>
                <telerik:BarSeries CategoryBinding="Category"
                                        ValueBinding="Value" 
                                        ItemsSource="{Binding Data}" />
            </telerik:RadCartesianChart.Series>

Workaround: 
Replace the axis: 
Use categorical axis for the horizontal axis and numerical axis for the vertical axis

Zooming on physical devices does not work properly (gets stuck). Same behavior when scrolling and panning the document 

 

When trying to scroll, pan, and zoom, these gestures open the flyout menu, not to the document in the viewer.

Release R3 2021 SP

there is a mistake with the accessibility modifier for `Telerik.XamarinForms.RichTextEditor.RichTextPasteType`. When it is Internal it's not possible to use the PasteCommand since it requires that type as input. 

 

Solution:

use reflection to get the enum

var assembly = typeof(RadRichTextEditor).Assembly;
var type = assembly.GetType("Telerik.XamarinForms.RichTextEditor.RichTextPasteType");
var obj = Enum.ToObject(type, 1);
await Clipboard.SetTextAsync("A pasted text");
var canExecute = richTextEditor.PasteCommand.CanExecute(obj);
richTextEditor.PasteCommand.Execute(obj);

Hi Team,

Were are using RadCalendar- Agenda View mode.

In that

a)we have to add an icon in some specific appointments. 
b)We also need a clicked event on that icon  to show a TOOL-TIP with some details in it. 

Have attached a snapshot for your reference.

Please let it know the possibilities

 

Thanks,

Vinu Priya

The image editor is a great start, but missing a critical feature - image drawing / annotation. The ability to draw lines, shapes or text onto an image. Should allow this to be done when pinch / zoom is in progress. Items drawn should be amendable until saved. Opportunity to retrieve the annotation only data separately to the image so you can preserve the original.

There seems to be 2 issues with Telerik ui for xamarin and Xamarin.AndroidX.Core versions 1.3.2.2 and newer where A) Linker seems to be failing when set to "Sdk Assemblies Only" on Visual Studio 16.9.0.

 

The other issue is with Telerik RadListView and same  AndroidX.Core at runtime I am getting the following exception:

System.TypeLoadException: 'VTable setup of type Telerik.XamarinForms.DataControlsRenderer.Android.ListViewAccessibilityDelegateCompat failed'

 

Please advise

Please refer to this issue: https://feedback.telerik.com/xamarin/1509502-errors-with-latest-versions-of-androidx

Hello this problem seems to be still prevalent in "Release" mode when using the individual libraries as well, in my case I am referencing the lite libraries from telerik nuget (Telerik.UI.for.Xamarin.Input.Lite + Telerik.UI.for.Xamarin.DataControls.Lite 2021.3.915.1).

There are no error when the workaround for this is to set Linking to "None". Project is latest XF 5.0.0.2196 with all latest AndroidX libraries: Project targets Android 10 (Q)

When the filter descriptor is used once to filter a column with a lot of items and then you reset the descriptor this results in freezing the datagrid.

Hello,

Let's say you have a view... You select multiple items in the combobox... Then you navigate away from that view, return, and you cannot bind the Combobox to previously selected items.

Well, you kind of can, but you can't. The combobox will happily display tokens, but it's just for display. They are not really selected.

Select some items:

(navigate away and back, bind SelectedItems to list above)

 

At this point, doing anything with these items will overwrite whatever was "selected".

By the way, this isn't visible in the screenshot above, but if you have a placeholder set up on the Combobox (I set it to an empty string), it will be shown on the right of the tokens. Which means the control really thinks it's empty.

 

TL;DR - cannot programatically set SelectedItems. The control's multiple selection mode is "one way to source", thus not usable in real world scenarios for editing data.

Combobox, selection mode multiple.

Select the third item:

 

And you get this:

(also note the +1 circle going over the border)

 

However, set selected items programatically, and you get this:

There's plenty of space in the control.

Open the dropdown:

Still plenty of space, but... the button has disappeared.

Collapse it by clicking somewhere outside the control and you get back to the measurement bug:

Currently, It's quite difficult to detect whether the text has been changed after the control is loaded completely.

And TextFormattingChanged event can not be raised when the text content is changed while text format isn't.

When you try to set the PickerPopupSelectorSettings.PopupViewStyle to a Style defined as a DynamicResource, the Style does not take any effect.  When defined as a StaticResource, it works as expected.
