BindingSource and Grid Grouping Control

[Ken]

Hi

I set GridGroupControl.dataSource to a bindingSource. When I do sort on
the table and use bindingSource.moveNext
or bindingSource.movePrevious,
it does not behave as MS DataGridView
which just move the selected row
to up/down based on next/previous.

Is this a bug I should submit an inccident.

Thanks

Hi Ken,

when you do the sorting you do the sorting on the TableDescriptor, correct?

In that case the records are sorted inside the GridGroupingControl and the original underlying datasource is not sorted. Therefore when you then navigate in the underlying datasource the navigation will still be in the old sort order. You should then navigate through grid.Table.SortedRecords insteads.

You can also instruct the engine to pass on sorting to the underlying dataview

Engine.AllowedOptimizations = EngineOptimizations.PassThroughSort;

hi,

First, grid.Table does not have
sortedrecord.
Second, set Engine.AllowedOptimizations = EngineOptimizations.PassThroughSort
does not not either.
I did put the above line during the
form_load, right before the bindingSource1.moveNext and
bindingSource1.moveNext.

Still it does not work.
Any better solution.

Ken, Sorry - I mean FilteredRecords, not SortedRecords. Attached find an example. You can also comment out the lines in the Form1 ctor. Then you see PassThrough mode in action. ggcbindingsource.zip Stefan
