Currently, the only way to set the TextColor for the RadNumericInput is to extract the ControlTemplate and set the TextColor of the internal NumericInputEntry component.

A simple and quick fix is to add a TextColor BindableProperty to the RadNumericInput control and use a TemplateBinding on the NumericInputEntry style

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.

I've attached a sample solution to demonstrate the issue. Try to run it.
When you run it you can see that it's not possible to see  value of numeric input until 
tapping on it  

Hello,

It would be nice to be able to change the color of the NumericInput.

Please consider adding 2 bindable property : ButtonBorderColor and ButtonContentColor.

I can't use this control as it is. I had to create my own control.

It should be easy to implement IMHO.

Best regards

Samsung numeric keyboards insert minus sign after the second stroke of a multi-functional button. This restricts Samsung end users to directly insert minus in the RadNumericInput because the control reacts on the beforehand entered decimal separator.

We should improve our logic in order to handle this type of input.

Available in the 2018 R2 SP release.

If you modify the property which is bound to the Value of the RadNumericInput, through the ViewModel for example, you are able to set a value which is not in the range of minimum/maximum.

Available in the R2 2018 release.

1. If there is "0" and you are trying to add "." (dot) after it - it doesn't allow you to do this (droid and iOS)

2. Start input from "." and you will see cursor before dot, not after it as usually is happening (droid only)

3. Start input ".0" and it changes to "0", if I want to get number e.g. 0.09 (droid and iOS)



Available in minor release 2018.3.1122. It will also be available in the R1 2019 release.

When using Xamarin.Forms 3.6 and UI for Xamarin 2019.1.316, the RadNumericInput control does not fire the Unfocused event (on Android and iOS).

Reproduce

This can be easily reproduced using the following code:

<telerikInput:RadNumericInput x:Name="BuyerAmount" Unfocused="BuyerAmount_OnUnfocused" StringFormat="{}{0:C2}"/>

Workaround

As a temporary workaround, I am able to get the Unfocused event from the ControlTemplate's internal NumericInputEntry control:

<numericInput:NumericInputEntry x:Name="PART_Entry" Unfocused="BuyerAmount_OnUnfocused" ...  />

This is a very unattractive solution as I need to define a separate ControlTemplate for every control instance that I need separate event handlers.

RadNumericInput on UWP crashes as soon as you copy something and paste into the input. And it doesn't matter whether the copied text is numeric (12 for instance) or a text. I've attached a sample to demonstrate the issue.

Steps to reproduce

1. Run the solution on UWP
2. When main page is loaded tap "Next Page"
3. Put the cursor focus onto the numeric input field
4. Without losing the focus tap back button
5. Application crashes


Available in minor release 2018.2.821. It will also be available in the R3 2018 release.

I've attached a sample solution to demonstrate the issue. Try to run it. There are two commands which change string format to currency and to percent  accordingly. So when you change string format by buttons on screen  it's not possible to see  it until  you tap on input 

Hello,

If you take a look to the provided screenshot you'll see what's wrong at first sight.

If you add a numeric input belong other kind of input.

You will see that the numeric input is the only one control to have a style which look like the control is being focused.

Current behavior

the NumericInput color is using the accent color for all states. We can't guess whether the control is focused or not.

Expected behavior

the numeric input should have a default color and use the accent color only when focused. Use the default entry style for the entry of the numeric input.

Workaround

you can also expose a numericButtonStyle property or some bindable property to allow us to set the color.

Right now, the control is unusable because of its look. Too bad, the implementation behind is nice.

It was better to create my own control which does the same. I use Telerik to avoid that.

Have a good day and thanks for your attention.

Best regards

Value is not applied correctly when StringFormat property is used (N format specifier): For example

 <telerikInput:RadNumericInput StringFormat="{}{0:N0}"
                                               Value="{1234.56543}"/>
