Lazy fetch for GGC child table rows

[Chinedu]

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.

Also take a look at the GroupingTraderGridTest sample in this [C:\Documents and Settings\User Name\My Documents\Syncfusion\EssentialStudio\5.1.0.51\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,
