Hi Neha, 
 
Good day to you. 
 
We have validated the reported issue in your provided sample and we found that you have not mapped the fields properly while assigning the dataSource which caused this issue. Please find the modified code snippets. 
 
for (let k = 0; k < this.showData.length; k++) { 
    this.showSelection.push(this.showData[k].text); 
    if (this.showData[k]["parentID"] === null) { 
        this.showData[k].hasChildren = true; 
    } 
} 
this.dataSelection = { dataSource: this.showData, id: 'id', parentID: 'parentID', text: 'text', hasChildren: 'expanded', data: 'data' }; 
 
Please check the below screenshot, 
   
 
 
Could you please check the above sample and get back to us if you need any further assistance in this? 
 
Regards, 
Vinoth Kumar S

Hi Neha, 
 
Good day to you. 
 
We have checked your query “it holds one data value while unchecking” and we can able to get all the data values while unchecking the same node. Please check the below screenshot, 
 
 
 
In your source code, you have not reset the datasource using this.dataSelection while unchecking the node. Could you please provide more information about your exact use case scenario whether you need to reset the datasource of second Treeview while unchecking the node or do you want to remove the nodes based on condition? Based on this we will validate and provide you better solution quickly.  
 
Regards, 
Vinoth Kumar S
