Hi, just check some odd things there.
The underline of the control is supposed to expand like this:
```
<StackLayout Orientation="Vertical">
<syncfusion:SfNumericTextBox FormatString="c" Value="123" />
</StackLayout>
```
Then I made the StackLayout's orientation horizontal to put some other controls in the line.
but the underline of the control was squeezed even I set it to Expand.
```
<StackLayout Orientation="Horizontal">
<syncfusion:SfNumericTextBox FormatString="c" HorizontalOptions="CenterAndExpand" Value="123" />
</StackLayout>
```
I mean, the control did expand, but not the underline, is it supposed to be like this?
I got a workaround to put in a grid, so just confirm.
Cheers.
