#1818 closed enhancement (done)

ColumnGroupView refreshes very slowly

Reported by: mkommend Owned by: mkommend
Priority: high Milestone: HeuristicLab.DataImporter 1.0.1
Component: DataImporter Version: branch
Keywords: Cc:

Description (last modified by mkommend)

A refresh of the ColumnGroupView takes too long and this makes the DataImporter unresponsive, although the commands execute quite fast. Especially when performing changes on the whole Dataset, this becomes an issue.

A quick examination, shows that the updating of row headers takes quite long and also disposing of views comes with a serious performance penalty.

r7731: The previous solution didn't work out.
Similar to the StringConvertibleMatrixView the ColumnGroupView now only updates the row headers which are displayed.
