|
|
Hi,
Currently the data contained in our virtual tree implementation is becoming quite large. This has consequences for the UpdateRowData call, even when running in a separate thread, as this slows down the refreshing of the view. Are there any ways to optimise its use?
I am thinking of looking at overridden methods in row- or cell binding that may be used (?) or maybe ways to stop a pending update if a new change has been added.
Thanks

It might be very practical if an updaterowdata was ended by spawning an event, so that a sandbox icon could be used during an update

The latest version of VirtualTree has a new overloaded version of UpdateRowData that takes a row parameter - this allows you to just update the data for a specific row. Even without the performance UpdateRowData should not be dependant on the size of your data - because it only updates the currently displayed rows/columns - which is only dependant on the height of your control and the number of columns displayed. _________________ Infralution Support |
