Xamgrid刷新或重新应用过滤器

Question

Is there some way to reapply the filter without having to reselect the filter? Especially when the underlying observable collection is changed? I seem to have records which don't match the filter condition after a while..

Answer 1

The XamGrid doesn't have a method to refresh. The INotifyCollectionChanged events are supposed to handle updating the grid accordingly.

You could try programmatically removing the current filters that are set and then readd them. It's a little tough for me to know if this will solve your issue though as I don't have a sample that reproduces the issue.

You could also try deriving from ObservableCollection and implement a refresh method. Inside the refresh method you could call OnCollectionChanged and pass in a Reset action. This might refresh the XamGrid.

Answer 2

您可以尝试调用XamGrid类的InvalidateData方法-应该使所有数据操作（如分组，排序和过滤）无效。
