Re: Grid (Sluggish Load)
Thank you for the feedbacks, Thomas and Trevor... I'm looking into the possible solutions now. Appreciate it...

Grid (Sluggish Load)
Hello, I have a regular Grid implementation with 5 columns that loads in 300 records within a DialogBox. Everything is fine until the actual return off of a Callback that handles the feedback from a data extraction routine intended to populate the Grid. Problem : The Grid seems to take an awfully long time to load the data (simple Strings) to a full 300 rows. Possible Solutions : 1. One solution I am considering is pagination of the data. 100 records seems to register a descent enough load time and do paging for the next set of hundred records. Anything over that seems to take the process down. 2. Another is the caching of the actual dialog box for succeeding use. The problem I see here is a refresh process (but this is another story). QUESTIONS : 1. Can anybody please share their point of view onto why the slow down is happening. I didn't quite expect this given the data to be just a set of String values. 2. I'm using a loop and going through each cell to set content in... Am I missing something in terms of how a proper way of loading a Grid is concerned?
