Inserting items while groups are displayed is slow #129

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Inserting items while groups are displayed causes the items to be sorted from 
scratch. This happens for each new item.

This will take some time to fix. Current workaround is to temporarily disable 
grouping while inserting items:

// Disable groups
myImageListView.SuspendLayout();
SortOrder oldGroupOrder = myImageListView.GroupOrder;
myImageListView.GroupOrder = SortOrder.None;
// Insert items
myImageListView.Items.AddRange(manyitems);
// Enable groups
myImageListView.GroupOrder = oldGroupOrder ;
myImageListView.ResumeLayout();
