I've got a question about how commands like "set the dgDataOfIndex" work under the hood, and whether there are occasions where you would get speed increases by directly setting the value of an individual control in a record view.
*First an introduction:* I've got a datagrid form I'm working on in which the data that makes up the individual form contents comes from a variety of web services - consequently the basic data comes over fast but the detailed contents (things like images and metadata) comes over much more slowly. The solution I'm trying to reimplement is based on asynchronously loading the additional data using "load url with message". I can then display the datagrid fast, and with a toggle arrow allow the user to reveal the image and metadata when needed. If the metadata is still loading then I want to display some suitable dummy "is loading" content. The issue here is that if a hundred or more records are loaded into a datagrid, then we will have several hundred asynchronous loads being fired off and coming in all trying to update / redraw the datagrid one at a time. Naturally this will need the fastest possible technique for updating the display of the metadata - but we (probably) want to do this as the data comes in. *The questions:* If I uses "set the dgDataOfIndex" to update the display of an individual datagrid form record, does the underlying library only update the display associated with this one record, or does the library redraw all the currently displayed records? Would I be any better off speed wise directly setting the images / metadata of records using over using built in datagrid api calls? _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
