Hello, 

i have integrated data form in our application, it's working fine in android, ios simulator, when we tried it in ios device (iphone XR) its load and views are good but when we clicked on text editor inside of data forms we face app crash. 

When you use a DataForm with a GridLayout and set ColumnSpan property of the DisplayOptions for two columns in the same row, only the second column is shown on the screen on Android.

In Android when an Entry is focused (and probably not only Entry) and you press Enter and expect to automatically tab to the next editor - it does not work. Sometimes the focus is not moved, sometimes the focus is moved to an invalid location like the first editor in the DataForm or an Entry outside the DataForm.

When the decimal separator is comma "," for example on a device with Spanish location (es-ES), and the source property is of type decimal,  the DecimalEditor of RadDataForm does not receive the decimal separator.

The issue is not reproduced with properties of type double.

AutoComplete editor does not have RTL support :
- The clear icon ("X") is on the right side and not on the left side.
- The list of options is aligned to the left on not to right.

The validation message is on the left side and not on the right side.

When setting a SliderEditor for a property of the DataForm source,  currently it shows only a slider - provide a way to display the slider value as well.

Currently DataForm for Xamarin.Forms provides ToggleButtonEditor and CheckBoxEditor for boolean values.  We can add a SwitchEditor as well, as it is available for the native Android and iOS DataForms.

For integer values users may use the IntegerEditor - provide a way to set the number formatting, for example add a thousand separator.
