How to group by a column that is not in Columns collection in Xamarin.Forms DataGrid?
SfDataGrid allows you to perform grouping by defining the GroupColumnDescription object and adding it in the SfdataGrid.GroupColumnDescriptions collection.
You can group by a column that is not in the column collection by simply adding the property to be grouped GroupColumnDescription and skip adding the column in the SfDataGrid.Columns collection.
You can skip adding a column in the SfDataGrid.Columns collections by manually defining the columns by setting SfDataGrid.AutoGenerateColumns as False. You can also skip adding a column using the AutoGeneratingColumn event for automatically generated columns.
The below code illustrates how to group by a column that is not defined in the SfDataGrid.Columns collection.
