Factors which effect our application performance

Add data to the end of collection (List, BindingList, ThreadSafeBindingList etc). Otherwise, internal implementation of indexed collections will move and re-index all data starting from the newly added index.

Avoid adding data to a binding list with more than 10 000 items when the grid is sorted. Stop sorting to improve performance. However, if you need to add large amounts of data in real-time to the beginning of the grid, it's better to use the following and visit dapfor. com

grid.Sort.Enabled = false;
grid.DataSource = _datasource_;

//Add a single object to the beginning of the grid
grid.Nodes.Insert(0, _new_object_);

//Add a single object to the beginning of the binding list
IBindingList bl = ...;
bl.Insert(0, _new_object_);
