CollectionViewSource不会更新ViewModel中的属性 [英] Collectionviewsource not updating the property in viewmodel

问题描述

<cmc:AutoRefreshCollectionViewSource

             x:Uid="CollectionViewSource_1" x:Key='sortedList'

                              Source="{Binding Path=MyList, Mode=TwoWay}" >
                <cmc:AutoRefreshCollectionViewSource.SortDescriptions>
                    <scm:SortDescription x:Uid="scm:SortDescription_1" PropertyName="HoldingRegister"

                                     Direction="Ascending" />
                </cmc:AutoRefreshCollectionViewSource.SortDescriptions>
            </cmc:AutoRefreshCollectionViewSource>

该collectionViewSource绑定到列表视图
如上面的代码MyList一样，ViewModel中的Observable集合


在这里进行排序，但是collectionviewsource没有更新回MyList

请提供解决此问题的建议

This collectionViewSource is binded to a list view
As the above code MyList the Observable collection in ViewModel


here sorting is happening but the collectionviewsource is not updating back to MyList

pls advice to solve this problem

推荐答案

最有可能在view和viewmodel之间丢失变量的拼写.
(请记住，这是区分大小写的.)

Most likely a miss spelling of your variables between view and viewmodel.
(Remember it is case sensitive).
