Greetings,

Populating a node on demand using server side callback is a wonderful feature. For the application I am planning to use Syncfusion's ASP.Net treeview it is mandatory, that collapsing a node will de-populate the node and re-populate it when expanded again (i.e. I need the possibility to refresh a node without having to post back the whole page to the server).

Is Syncfusion's Asp.Net TreeView capable of achieving this?

Hi Martin,

Thanks for your appreciation.

Our TreeViewNode control has the property 'ExpandMode' which can be categorized into 3 types as

1.ClientSide : Default value
2.ServerSide : Causes a postback when the 'NodeExpanded' event is triggered.
3.ServerSideCallback: Callback occurs and allows to add nodes dynamically as in the Load On Demand sample.

But we do not support such property when the nodes are collapsed. I will forward a feature request regarding your requirement to our 'Essential Tools Development Team' and update the time frame within a week as when this feature can be implemented.

At present your requirement can be achieved when there is a postback.

Please let us know if you have any further concerns.

Regards,
Valli.
