MudBlazor: MudDataGrid regressions in v6.2.0

Users have reported the following regressions in MudDataGrid since v6.2.0

With the example here: https://dev.mudblazor.com/components/datagrid#grouping It is already grouped but I can still select “Group” for the column “Molar mass” which results in an error. (reported by @dennisrahmen)
I found that GroupExpanded=“true” does not do anything as you can see here the groups are still collapsed on load. (reported by @dennisrahmen)
When I use Serverdata with filter the get serverdate is not called when using filtermode ColumnFilterMenu and ColumnFilterRow It is working with filtermode Simple. (reported by @lfhenrl)
When the column type/data is DateTime the filter popup is not showing anything. (reported by @lfhenrl)
PropertyColumn with a nullable datatype causes NullReferenceExceptions with null values (reported by @HClausing)
#6621 (reported by @joelmnz)
Every time I open the filter menu/popup It add a new filter definition. My suggest is to only add it when I push the Filter/apply button and the Value is not null. (reported by @lfhenrl)
It should be possible to set the @key for each row/cell (@tjscience)

Is there any code snippet for

When I use Serverdata with filter the get serverdate is not called when using filtermode ColumnFilterMenu and ColumnFilterRow It is working with filtermode Simple.

Looks like this is the only serious bug left? The rest in this list sound more like an enhancement. And when this one is fixed I believe we can do a stable release?

I kinda want to add this to the list too, since it worked prior 6.2.0 https://github.com/MudBlazor/MudBlazor/issues/6621

Great, I’ll see if I can help with the rest of the regressions.

@henon I have a branch that fixes the GroupExpanded=true regression, it’s missing relevant tests for now, I intend to add them later, but it needs PR #6592 merged first so I hope you can find the time to check it out.

@HClausing yeah, haven’t tested it but I think it should do the trick, and even without the the null-coalescing operator item.Grouping.Key?.ToString() == "Nonmetal" || item.Grouping.Key?.ToString() == "Other"
