DataGrid: add access to columns

[ksbecker]

🙋 Feature Request

Give developers access to the collection of columns in a DataGrid.

🤔 Expected Behavior

In order to programmatically set the sort, remove sort, or show column options, you need to pass in a ColumnBase<TGridItem> into one of the methods, RemoveSortByColumnAsync, ShowColumnOptionsAsync, and SortByColumnAsync. As far as I can tell, there is no way to get a reference to the columns.

😯 Current Behavior

Currently there is way to access this collection.

💁 Possible Solution

There is a private field that contains a list of ColumnBase<TGridItem> that could be exposed through a getter property.

🔦 Context

What I'm trying to accomplish is to store the state of the DataGrid and restore it when navigating back to the page. I have filters and paging working, now I need to be able to restore the previous sort order. I can accomplish this by storing an index/unique id of the column that was sorted and then applying the SortByColumnAsync method.

💻 Examples

I think this is fairly straight-forward. Basically add a new property in fluentui-blazor/src/Core/Components/DataGrid/FluentDataGrid.razor.cs

public List<ColumnBase<TGridItem>> Columns { get => _columns; }

Alternatively, methods could be created to give access to these columns, GetColumnByTitle or GetColumnByIndex

By exposing a getter, you would have read only access to the collection of columns. But then nothing would stop you from manipulating the individuial columns from that collection, right?

I see more value in providing the other type of methods you mention.

As we only have limited time for working on this, care to work on a PR?
