Initial source and virtualModeCreateRecords

[JonAParticipant]

Hi!

I’m trying to accomplish the following:

* Load an intial tree-structure to the TreeGrid
* When the user expandes a node that has children that hasn’t been loaded initially, I would like to use the virtualModeCreateRecords to fetch this nodes children.

Ergo, I’m trying to combine both the initial population of the grid With dynamically loading the rest on demand.

The problem is that if I set the Source of the TreeGrid on initialization, the virtualModeCreateRecords-function never fires…
On the other hand, if I only use the virtualModeCreateRecords-function, (also to populate the tree initially), the tree does not respect the hierarchy of this data, and everything is added on the root-level.

Any tips?

Thanks!

Regards
Jon

Hi Jon,

It is not possible to combine these. You should either always use virtualModeCreateRecords or never use it. The first call of the virtualModeCreateRecords defines the Root Level. Other calls of that method populate each Expanded Item.

OK, so just to re-cap: Starting with an initial tree, then continuing With dynamically loading data when user expands nodes is not at all possible in the TreeGrid? No work-arounds that springs to mind?

Hi Jon,

It is not possible to combine different data binding modes. You should either Load Records on Demand or load them at once.
