Hi Michael,

Based on the provided details we have checked the reported issue “Mono.Linker.MarkException” when compiling the SfDataGrid with SKD assemblies only. We could not able to reproduce the issue in our end and it is working fine as expected. We have attached the tested sample and video for your reference.

Unfortunately, I wasn't able to reproduce it too on a new project with below data grid. Now the production app has Linking set to None..

           <sfgrid:SfDataGrid
                                         ItemsSource="{Binding Statements}" VerticalOverScrollMode="None"
                                         AutoGenerateColumns="False"  ShowRowHeader="False"  ColumnSizer="Star" GridTapped="dataGrid_GridTapped">
                <sfgrid:SfDataGrid.SortColumnDescriptions>
                    <sfgrid:SortColumnDescription ColumnName="tran_date"
                                          SortDirection="Descending" />
                </sfgrid:SfDataGrid.SortColumnDescriptions>

                <sfgrid:SfDataGrid.CaptionSummaryTemplate>
                    <DataTemplate>
                        <StackLayout VerticalOptions="CenterAndExpand" >

                            <Label Text="{Binding Key, StringFormat='{0:dd MMMM}'}"
                                               FontFamily="Montserrat-Bold"
                                               TextColor="#102A53"
                                               HorizontalOptions="Center" VerticalOptions="CenterAndExpand" />
                        </StackLayout>
                    </DataTemplate>

                </sfgrid:SfDataGrid.CaptionSummaryTemplate>

                <sfgrid:SfDataGrid.GroupColumnDescriptions>
                    <sfgrid:GroupColumnDescription  ColumnName="tran_date"  SortGroupRecords="True" />
                </sfgrid:SfDataGrid.GroupColumnDescriptions>

                <sfgrid:SfDataGrid.Columns x:TypeArguments="dataGrid:Columns">
                    <sfgrid:GridTextColumn MappingName="tran_date" Padding="30,0,0,0" HeaderText="Transaction Date" IsHidden="True" TextAlignment="Start" />
                    <sfgrid:GridTextColumn MappingName="reference" Padding="30,0,0,0" HeaderText="Reference" TextAlignment="Start" />
                    <sfgrid:GridTextColumn MappingName="amount" HeaderText="Amount" TextAlignment="End" Padding="0,0,30,0" Format="N2" >
                        <sfgrid:GridTextColumn.CellStyle>
                            <Style TargetType="dataGrid:GridCell">
                                <Setter Property="Foreground"  Value="{Binding amount, Converter={StaticResource NegativeNumberToBoolConverter}}" />
                            </Style>
                        </sfgrid:GridTextColumn.CellStyle>
                    </sfgrid:GridTextColumn>
                </sfgrid:SfDataGrid.Columns>

            </sfgrid:SfDataGrid>

Hi Michael,

We are glad that the issue is not replicated in your new sample. 

  

We have also tried replicating the issue based on the provided code snippet and the configurations of the android project. But we were not able to replicate the “Mono.Linker.Exception” issue. 

  

We have attached the tested sample for your reference. So, could you please test your application with and without SfDataGrid and let us know the details? Or please do conform us that the new sample is working fine in all configurations and no more assistance is required with this regard.
