DataGrid: Add support for expanding/collapsing groups programatically

Currently, all groups are expanded by default. We should expose methods to collapse/expand certain groups. Furthermore, CollapseAll, ExpandAll groups should be considered as well.

Hello Sadanan,

Thank you for pointing out that the documentation was also missing the feature instructions. I just finished writing those instructions and submitted this Pull Request with the content. Once it gets merged, it will be live in the following documentation update.

I have updated your Telerik Points as a small token of appreciation for bringing this to our attention.

Thanks for the quick response. Please also update documentation highlighting that this is possible. https://docs.telerik.com/devtools/xamarin/controls/datagrid/grouping

I do have questions about dataview for which I will create support ticket.

Hello Sadanan,

You can now programmatically expand/collapse groups using the DataView of the RadDataGrid.

Here's en example:

var dataView = DataGrid.GetDataView();

dataView.ExpandAll();

dataView.ExpandGroup(use the IDataGroup reference here);

dataView.ExpandItem(use data item's object reference);

dataView.CollapseAll();

dataView.CollapseGroup(use the IDataGroup reference here);

dataView.CollapseItem(use data item's object reference);

If you have any further questions or need assistance using the DataView, please open a Support Ticket and share the relevant code so that we can directly assist.

I was actually looking for this feature and now surprised to find this request pending since years. I should probably stop looking for it and move ahead because it isn't in your priorities :(
