How to group by a column that is not in Columns collection in Xamarin.Forms DataGrid?

1 min read

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.

<ContentPage.Content>
<syncfusion:SfDataGrid x:Name="dataGrid"
                        ColumnSizer="Star"
                        AutoGenerateColumns="False"
                        ItemsSource="{Binding OrdersInfo}">
  <syncfusion:SfDataGrid.Columns>
    <syncfusion:GridTextColumn HeaderText="Order ID"
                                MappingName="OrderID"/>
    <syncfusion:GridTextColumn HeaderText="Employee ID"
                                MappingName="EmployeeID"/>
    <syncfusion:GridTextColumn HeaderText="Customer ID"
                                MappingName="CustomerID"/>
    <syncfusion:GridTextColumn HeaderText="Last Name"
                                MappingName="LastName"/>
  </syncfusion:SfDataGrid.Columns>
 
  <syncfusion:SfDataGrid.GroupColumnDescriptions>
    <syncfusion:GroupColumnDescription ColumnName="FirstName"/>
  </syncfusion:SfDataGrid.GroupColumnDescriptions>
    
</syncfusion:SfDataGrid>
</ContentPage.Content>
