Exception "specified cast is not valid"

Question

We are using the latest stable release of SfDataGrid.

SfDataGrid Version: 16.1.0.37

We have an exception for NumericColumns with AllowEditing set to true.

This is observed in Android Forms Application

The exception thrown is "Specified cast is not valid".

Further,

When we change the columns to TextColumns, we are able to edit the columns.

Of course, we get a alphanumeric keyboard instead of numeric keyboard.

Here are the package information.

Hi Venkatesh, 
Thank You for using Syncfusion Products, 
We had analyzed your query and checked your replication procedure. We had confirmed that the Numeric Column Exception does not occur while editing in our side. We also recommend to use Xamarin Forms 2.4.0.280 Version in the sample. 
Please refer the below link for Xamarin Forms Compatibly map

We need to know that your issue exists in Xamarin Android or Xamarin Forms Android? because this similar issue exists in Xamarin Android but not in Xamarin Forms Android. 
 If your requirement deviates from us, please send the sample or code that you have been facing issue 
We had prepared and attached working sample for your reference, you can download it from below link
