Lazy fetch for GGC child table rows

Asked On June 18, 2007 01:28 PM UTC

I have a dataview with a parent-child relationship from two data tables.

Because of the potential for the amount of data in the child table to grow heavily, i want to fetch the child rows on demand/lazily.

I want to display the "+" sign next to the rows on the grid and when the "+" sign is clicked for expansion, I want to hook-in at that point, fetch the related child row from the DB and display it, or diplay an empty row if no child records exists.

Hi Nedu,

Below are the forum threads that discuss with similar task.

Also take a look at the GroupingTraderGridTest sample in this [C:\Documents and Settings\User Name\My Documents\Syncfusion\EssentialStudio\\Windows\Grid.Grouping.Windows\Samples\2.0\PerformanceSamples\GroupingTraderGridTest\CS] to see the optimization settings within the new code base. There are comments there that explain the settings for better performance. Also refer the samples under the "PerformanceSamples" category.

Best regards,
