How to keep expanded GroupByRecords still open after refreshing
posted

 Hi,

I am facing an issue, that is, how to keep the expanded records(when existed groupin) still open after refreshing? for example, I have such a grid with 3 fields(columns) and some records below:

Name   Age   Description

John     25     Sr. Developer

John     26     Tester

Andy    28      Project Manager

Susie   26     Developer

Andy    30     Dev. Manager

 Supposed currently a user has grouped it by Name and Age fields, and has expanded the group with the name of John to the lowest level. now my question is how to keep such an expanded group state and the active record after refreshing? sure, there is another question, that is how to make XamDataGrid refresh automatically once there is any changes to the underlying data source when using data binding?

Anyone knows how to achieve that? Thanks your any help!

    Hello Corin,

    Thank you for your post. I have been looking through it and I suggest you implement INotifyPropertyChange interface in your data Classes in order to ensure that the changes made in the underlying data will reflect in the XamDataGrid. Also it seems like that if the data is refreshed, such behavior like your doesn’t occur on my side. If this is still an issue could you please provide me with an isolated sample project, so that I can investigate it further for you.
