Hi,
Kindly find attached for the tree view sample codes and follow the below steps.

Step to do:

1. First select the parent Australia
Now all children under Australia selected automatically
2. Now in search type "acre".It works fine.
3. Now clear filter
4. Un-check New South Wales, Victoria, south Australia and western Australia
5. Now u can see Brazil, Parana, Ceara, Acre checked
6. Now in search bar type "a"
7. you can see all children under Austrralia is checked.

The output shown is wrong,
Because i have unchecked the New South Wales, Victoria, south Australia and western Australia, how it got selected/checked.

Thanks,
-Ebe

Hi Ebenezer,  

Sorry for the inconvenience caused.  
 
We have followed the steps as you provided in your first update. But we were unable to reproduce the issue in that case. Please check the image 
But while following the below steps we can able to reproduce the issue which is reported by you 
1.       1. After unchecking the New South Wales, Victoria, south Australia and western Australia, we again type acre in search box. 
2.       2. Now acre with its corresponding parent Nodes get checked 
3.       3. After clearing the filter, we found that all the nodes under Australia get checked. 
We overcome this issue by maintaining the indeterminate nodes in separate array and make it check only when it is changed by user interaction. 
 Note: You can disable the autoCheck property to achieve the independent checked state of parent and child Nodes 
Please check the sample and get back to us if we misunderstood your query or need any further assistance. 
Regards, 
Balachandar M.
