Hi, we're using syncfusion treeview

In the event node check we invoke a query for show in a grid the result, now when we check a node parent a delay is observed in the execution of the query, because we've observed that the query is called for each child node.

Now exist an event for can inspect all the nodes checked just one time for execute the query just one time.

Hi Roimer,


Thank you for contacting Syncfusion support.


We are unable to reproduce the  issue you are facing on updating query for every child nodes. Because on binding NodeCheck event in TreeView will trigger the event only once on checking the parent node and the child node check events will not be triggered. Could you please confirm with us whether ClientSideOnNodeChecked event or server side OnNodeChecked event used in your end? Also how you are updating the query for grid on node check event. Please share us related code snippets or issue reproducible sample and the scenario used in your end  with us, so that we can provide an appropriate solution.


Please let us know if you have any queries.
