no method 'OrderBy' exists on type 'System.Linq.Queryable' error when sorting

[Jason]

I have an issue where the sorting is causing a runtime error in the SfListView.

I used the online demo to setup the sorting....

            <sync:SfListView.DataSource>
                <dataSource:DataSource>
                    <dataSource:DataSource.SortDescriptors>
                        <dataSource:SortDescriptor PropertyName="SortOrder" Direction="Ascending" />
                    </dataSource:DataSource.SortDescriptors>
                    <dataSource:DataSource.GroupDescriptors>
                        <dataSource:GroupDescriptor PropertyName="OwnerName" />
                    </dataSource:DataSource.GroupDescriptors>
                </dataSource:DataSource>
            </sync:SfListView.DataSource>

The property SortOrder is a calculated field in the object, the items bound to the SfListView is a list of objects List<T>.

Any ideas what could be causing this issue?

Hi Jason, 

 

Thank you for contacting Syncfusion Support. 

 

The issue you are facing is possibly a known issue in Xamarin framework that occurs when the linker mode is set as LinkFrameworkSDK’s in iOS platform. We recommend you to try the steps mentioned in the following KB link.

Please note that this is a Xamarin framework linker issue in iOS platform, so please don’t be confused with SfDataGrid control or title of the KB. Fortunately the issue and the solution are the same for both the Xamarin.Forms.iOS and the Xamarin.iOS platforms.
