AutoPostBackOnNodeSelect

We have a TreeView using LoadOnDemand. Works fine, the treeview gets populated, but when I select one of the created items the serverside nodeselected event is not raised. When I select a second one, the event gets raised. Any chance to get the event raised on the first click? The treeview is placed within a .net update panel.

Hi Martin,

Thank you for your interest in Syncfusion Products

I'm afraid that I’m not able to reproduce the issue reported by you. Kindly refer the sample in the below link which showcases the server side events of a tree view. In the sample select the AutoPostBack On Select option and select the nodes to fire the NodeSelect event.

Please let us know if any concerns.

Hi,

I provided you a sample which should illustrate my problem. After starting the sample, click on the parent node to expand it with an async server call. After that click on one of the two child nodes. The event is not fired. If you then click the other node, the event gets fired.

Thanks for your help.

Greetings,
Martin
