when using automatic column generation you don't have easy access to the column being created so that you can apply customizations (Header, style, etc).

Please implement the same event that UI for WPF has, see it here: https://docs.telerik.com/devtools/wpf/controls/radgridview/events/column-resize-event#autogeneratingcolumn

By specification, names are an atomic symbol uniquely defined by a sequence of characters. However, when importing a document with names defined as an empty sequence a handled InvalidCastException is thrown which leads to missing page content.

I think a "SignPad" would be a very nice new feature for XF.

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.

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.
