Category: UI for Xamarin
Type: Bug Report

I have a Xamarin.Forms app, but I only am using it for UWP at the moment. The plan is to have Android and iOS later, but I am having issues with the RadNumericInput (Xamarin.Forms) and how the decimal key is handled.

Here is my XAML

<tkInput:RadNumericInput Grid.Row="4" Grid.Column="1" Value="{Binding Price, Mode=TwoWay}" StringFormat="{}{0:C2}" />

Right now, "Price" will default to 0. The UI will initially show $0.00 because of the StringFormat. That is working fine. When I put focus into the control, I only see 0, that is also fine. The issue is when I try to type a decimal. The value disappears and I see an issue in my Output that says -- Binding: can not be converted to type 'System.Int32'


Example steps:

  • With the value set to 0.00
  • Focus the control -- you will now see just 0
  • Press the decimal key (aka the period key)
  • Notice the error in the Output window in VS and also the control shows nothing at all
  • If you press the decimal key again, you will see two decimals in the control

**** Also, the Version of the Telerik controls I am using is -- 2019.2.603.360. The drop down below doesn't let me choose that version.

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.

If you set SelectedDate when the Calendar control is created, does not take any effect in the UI on iOS. 

As a workaround, set SelectedDate at a later stage.

This can be reproduced in the SDK examples ->ListView -> Gestures -> CellSwipeEvents. 
1. Change the content of the items so that they have uneven height
2. Scroll down 
3. Delete an item by swiping
-> Expected result : The items re-arrange correctly
-> Actual result : The item is deleted but the ListView is scrolled up when the UI is updated

Please let us know:

  • Should the color be applied to the expand indicator as well, or should there be a separate property for this
  • Should the color be applied to the checkbox as well, or should there be a separate property for this

Native UWP calendar in DayView/MultiDayView Mode has a property which helps you specify height between the time lines. Please provide this option for Android and iOS too.

When the DataGridPickerColumn ItemsSource property is bound to a collection not part of the business object used for the DataGrid, and ItemDisplayBindingPath is used, null reference exception is raised when selecting items in the picker.

I would need to control when the overlay keyboard will appear, for example, hide it when the Entry gets the focus.

When you initiate a swipe gesture and the SwipeContentTemplate is shown,  changing the device orientation from portrait to landscape, does not update the ListView layout and the swiped item width is incorrect.

On iOS there is an initial animation when the page with the SegmentedControl is loaded. Provide API to suppress that animation.

It would be nice if we can just bind a .net DataTable or DateView as ItemsSource to the RadDataGrid.

Xamarin.Forms Entry with IsPassword=true does hide the suggestions
Last Updated: 28 Aug 2019 07:43 by ADMIN

If we have a ListView with a CheckBox inside the ItemTemplate and the whole ListView is placed in a Popup control, following the next steps:

1. Open the popup

2. Check and uncheck the CheckBox control in any of the items.

3. Click into the popup and then outside to close it.

NullReferenceException is raised on iOS.

Hi there,


We're struggeling with the radentry control. For login purposes we use one for the password and one for the email. When we set IsPassword=true this does show dots instead of words, but some basic stuff isn't working.

1) The normal entry with IsPassword=true does also hide the suggestion tab that is above the keyboard. We also tried hiding this with other settings but to no result. This control should also hide suggestions since it is a password and we don't want to cache this in any way.

2) When we replace the radentry password field with a xamarin entry password field (so set IsPassword=true on both) then we also get the password fill option. In this case Samsung keypass. I imagine if people are using autofillers such as samsung, google, or something else, that this should also work since i'm stating the field is a password field.

Tested on android with multiple devices.

Thanks in advance!

Expose an IsEnabled property for editors that can be toggled after DataForm is rendered.

Currently, only Data Annotations can determine whether or not a property's editor is read-only. If a specific editor's read only state needs to be changed dynamically (e.g. due to a selection in another editor), you would need to completely reload the DataForm.

Add public-facing methods to re-call DataSourceProvider GetSourceFor methods. This would allow for refreshing the datasource.

Alternatively, add support for ObservableCollection to be used for DataSources so that the pickers reflect any changes to the underlying data source.
