Eager Load ChildRows in Hierarchical Grid

yudi — Thu, 05 Aug 2010 17:55:28 GMT

Please try to set the value of HierarchicalMode property to “Preload”.

HierarchicalMode property specifies the operation mode when the WebGrid is configured to use Hierarchical feature. There are two option of value:

LoadOnDemand,
WebGrid will use LoadOnDemand model in displaying hierarchical data.
Preload,
WebGrid will use Preload model in displaying hierarchical data.

Hope this helps.

Eager Load ChildRows in Hierarchical Grid

Hi,

Is there any way to eager load the child rows in a hierarchical grid? What I mean is... everytime I click "Expand" on a parent row (and the child rows aren't already loaded) there's a FlyPostBack to create the childrows (triggering as many times as needed the InitializeRow event for those rows/tables).

Is there a way to render all children in one go(Effectively preventing that extra flypostback) ? I have a scenario that is pretty intensive on clientside programming and end-users notice the difference even if it's a flypostback.

For any example you can refer to the hierarchical grid (using a DataSet) I present in this thread.
