Hi Praful,
Thanks for using the Syncfusion products.
We have prepared a sample with Treeview “NodeSelected” event
to check the issue and the issue is not reproduced. The sample is available in
the below link,
TreeView_Server_nodeclick.zip
Kindly have a look at the sample and if the issue still
exists, could you please inform us the Essential Studio version which you are
using? so that we can check the issue with that version dlls.
Note: We have checked the issue with our latest version
v11.2.0.21 dlls.
Please let us know if you have any other concerns.
Regards
Dharmalingam S
