Hi

I don't want the GroupbyArea getting expended. I want the generated groups (at least some of them ) itself expanded.

Ok, then try this in code-behind:

this.xamDataGrid.Records.ExpandAll(true);

Regards

ok thanks

is there a way to achieve this via xaml ?

and second question: how can i expand an specific groupbyheader ?

Hello Imran,

Another approach you can try is to handle the XamGrid's Laoded event and use the same code as in the sample I sent you. Thsi way you won't need to add references to Interactions and Interactivity assemblies.

Hope this helps you.

Hi Stefan,

Hope it may work but we are not using Blend at all so we don't have dlls from Blend. and please advise if it will be good idea to add Microsoft.Expression.Interactions in the project? If possible then can you purpose some alternate solution?

Thanks

Hello Imran,

Thank you for your post. I have been looking into it and I created a sample project for you with the functionality you want. Basically I used Interactions to handle the XamGrid’s Loaded event in the ViewModel and there I loop the Rows and expand them if they are GroupBy rows. Please let me know if this helps you or you need further assistance on this matter.

Looking forward for your reply.

Hi Stefan,

We are using XamGrid and have made a column IsGroupBy=True to apply grouping by default and it is working fine except one thing that we want to make all rows expanded. We are using MVVM so can you help us in this regard. as we are not able to explore any propert related to this feature secondly there is no event called InitializeRecord in XamGrid.

Thanks

Hello Haggy,

Thank you for your post. I have been looking through it and I suggest you use the InitializeRecord event of the XamDataGrid which is fired every time a new Record is displayed in the XamDataGrid. The RecordAdded event is fired only when you add new item through the XamDataGrid’s AddNewRecord. The ObservableCollection has its own event called CollectionChanged which is fired when the collection is changed. Please let me know if this helps you achieve your goal.

Looking forward for your reply.
