Hello,

i have the following data structure in my treeview:

{"id":'root',"parent_id":0,"name":"Root","subChild":[
{"id":1,"parent_id":0,"name":"Test Folder","subChild":[
{"id":2,"parent_id":1,"name":"Child 1"},
{"id":3,"parent_id":1,"name":"Child 2","subChild":[
{"id":4,"parent_id":3,"name":"Child 3"}
]
}
]
},
{"id":5,"parent_id":0,"name":"User 2 Folder 1"},
{"id":6,"parent_id":0,"name":"User 2 Folder 2"}]
}


Is it possible to select a node programmatically through it's id? For example i want to select the node with id 4.
Single node selection mode.

 
I tried

document.getElementById('treeview').ej2_instances[0].selectNode(id);

but without success.


Thanks in adavance

Hello Christopher, 

Thanks for contacting us. 

You can programmatically select a node in TreeView by selectedNodes property. Here we provided the selectedNodes property in the dataBound event of TreeView. Kindly refer to the following code snippet. 

dataBound(args){ 
    if (args.data.length > 0) 
        this.$refs.treeObj.selectedNodes = ["4"] 
}, 

We have attached an example for reference, please find it in the following location 

For further reference, please refer the following API reference: 

Let us know if you need any further assistance. 

Regards, 
Prince
