Fastest way to hide rows?

[Maxim Software Systems]

I''m currently using a simple GridControl and need to hide a few dozen scattered rows once in a while. I''ve been repeatedly calling the SetRowHidden method, but it seems very slow. Is there a faster way to hide individual rows?

Hi Don,

We have updated new logic that increases the performance while synchronizing the Hidden rows/cols with the scroll grid. It will be available in our coming 4.4 release.

GridScrollVisibleElementsMapper in GridScroll.cs (src\Base\Control)

#region NewHiddenScrollLogic
GridScrollVisibleElementsMapper visibleColumns = new GridScrollVisibleElementsMapper();
GridScrollVisibleElementsMapper visibleRows = new GridScrollVisibleElementsMapper();


///

/// Use this class if you have an array of rows or column elements
/// and you want to be able to hide a range of rows or columns. The
/// class uses binary trees to map from original to visible position
/// and vice versa.
///

internal class GridScrollVisibleElementsMapper
{
......
.......
