Delphi XE3, LMD 2019.1.0.0.
When printing an ElXTree, I change the fields being printed according to user preferences, and then change them back again after printing.
Using ElXTree.Items.BeginUpdate(), the XTree is visually frozen from changes and EndUpdate().
Really nice. I speeds up the process considerably.
I expected the same to occur with ElXTree.HeaderSections.BeginUpdate, but it doesn't prevent the tree from updating on the screen.
The user would see the headings change without the data changing.
Is there a way of making this work?
If not, please make it work before June.
If you can't do that, please tell me how to change the source so that it does this.
