Filling a grid in background |
Mon, Jan 15 2007 10:51 AM | Permanent Link |
This is probably something a lot of people would like to do, so I hope I
am travelling well trod ground with this question: How can I fill the data storage of a Dev Express grid from a DBISAM query in the background? The key being that the grid loads all the data in one go, and I can have a lot of it. The UI freezes for a while when I have a few windows like this open, so I wonder if there is an easy trick to do the update in a background thread? /Matthew Jones/ | |

It depends whether or not you still need the autosort/filter etc. If not needed or you have no problem writing these source lines yourself changing the gridmode to true will make the grid load fast. |

I would like the filtering etc of the grid. I suppose my ideal is that the
thread could load a data source thing of theirs, and then when ready the main thread links it to the grid. Perhaps I ought to ask on the dev express forums since it is more their issue than DBISAM. /Matthew Jones/ |
