Summary

0007242: Optimize DataGrid fetch logic to use one bigger request instead of two distinct small request

Description

The current datagrid does request two, non-overlapping ranges of the data. Using a single bigger fetch request could/will lead to improved performance.

Steps To Reproduce

Go to the Business Partner selector
Resize the window that only two lines are shown
Position the marker/cursor on the first line
Open a Firebug or a similar tool to log the requests sent to the server
Press the "end" key on the keyboard do directly go to the last line
- See that two requests and sent to the Server.
  - Check the post parameter for the two requests
  - See the the offset,page_size of the requests
    specify two non-overlapping regions around the currently selected
    (target) line.

Proposed Solution

Optimize the code in the datagrid.js file to issue one combined fetch request which does request on region containing both needed ranges.
