Hi,
we use the code attached below. The grid load method is called multiple times in a for-loop. In each iteration we have an alert box popping up. If we click the ok buttons in the alerts slowly, all xml files from all loops are rendered in the grid.
But if we click the ok buttons in the alerts very fast, only some xml files of the loops are rendered in the grid.
What extra code do we have to implement, we need all xml files in one grid?
Thank you.
Regards, Marc

a) the grid.parse and grid.load methods purposed to load all dataset at once, not items one by one
b) the behavior highly depends on the data in responses, but in any case the grid use single loading element for load command, so when you executing new loading command before old finished - old loading will be dropped in favor of new one. To resolve issue you can try to use
theTaskGrid.xmlLoader=new dtmlXMLLoaderObject(theTaskGrid.doLoadDetails, theTaskGrid, true, theTaskGrid.no_cashe);
theTaskGrid.load(workItemsRequest, "custom_xml" );
With such approach , new loader will be created before each request, so multiple load commands can be executed in the same time
