There was a bigger change here, but the approach turned out to have some problems with large sets. The current app saves and restores the selected rows when you make an edit, retaining the set of selected bytes even if the number of lines changes (maybe you reformatted bytes into a string). There's no way to do that quickly with WPF when the number of selected items gets large (say 10K+). I will probably just cap the selection, and refuse to restore it if it exceeds a certain size. The ListView SelectedItems management seems to use an O(n^2) (or worse) algorithm. It might be trying to verify that items being added to SelectedItems actually exist in Items -- I can see it calling Contains(). Whatever the case, it's a big step backward performance-wise from WinForms. Yay WPF. See the DisasmUiTest project's Selection Test to see what I tried. |
