How to resolve the issue with decimal point and minus key on Samsung devices in SfNumericUpDown

Platform: Xamarin.Forms |
Control: SfNumericUpDown |
Published Date: May 15, 2019 |
Last Revised Date: May 16, 2019

When using virtual numeric keyboard in SfNumericUpDown, decimal point and minus sign will be missing on some of the Samsung devices.

To resolve this issue, follow the below steps:

  1. Create a custom SfNumericUpDown by inheriting the SfNumericUpDown class.
  2. Likewise create a CustomNumericUpDownRenderer class by inheriting SfNumericUpDownRenderer.


Code of Custom Renderer in Android:

[assembly: ExportRenderer(typeof(CustomNumericUpDown), typeof(CustomNumericUpDownRenderer))]
namespace Samsung_issue.Droid
 public class CustomNumericUpDownRenderer : SfNumericUpDownRenderer
  protected override void OnElementChanged(ElementChangedEventArgs<SfNumericUpDown> e)
   if (Control != null)
    for (int i = 0; i < Control.ChildCount; i++)
     var child = Control.GetChildAt(i);
     if (child is EditText)
      var control = child as EditText;
      control.InputType = InputTypes.ClassPhone;



Image represent the decimal point and minus key missing issue on Samsung devices in SfNumericUpDown.
