I'm using a multi column treeviewadv control. When there's a lot of records and you shift click from the first record to the last (to select all) the time it takes to process is incredibly slow. For 1300 nodes it takes about 12 seconds on my dev box.

Are there any known work arounds for this? Ironically if I start selecting from the bottom to the top the same number of nodes takes less than a second.

Additionally if you start at the bottom of the list and shift click to the top it goes about 1 billion times faster.

Any ideas what's up with this?

Hi Aerathi,

Thank you for your interest in Syncfusion products.

By default, MultiColumnTreeView select the nodes from Top to Bottom so the when you click on Last node it takes time to select the Nodes. Please use the MultiColumnTreeView events in Application to avoid this issue sample attached in following link.

Please let me know if you have any queries.
