I am trying to bind a kendo grid with data from tree view node click. So when user clicks on node 'A' of tree view then grid should get populated with data corresponding to that node.
1. How do I update the grid data while traversing through tree. I am reading data from an array.
2. Is there a way to just update the data without recreating grid or resetting the grid.?

I have a kendo angular tree-view with flat data binding. There is a section for filtering the nodes with heterogenous data(search elements inside the treeview). Any update how to filter the nodes for flat data ?
I am using a kendo grid to display my data. I want to show another kendo grid inside one cell of my kendo grid. Is there anyway I can achieve this?
There is a 'way' (using the "template" option of the corresponding Grid column), however I would suggest to instead use Grid hierarchy to show details about current row:
Grid: hierarchy demo
Nesting another Grid inside cells of current Grid is not a good idea as it will not be usable, it will reduce the page performance etc.
I have hierarchical data for the tree and I want to show only part of the leaves and later to add more leaves to the tree when a button is clicked for example.
One solution I thought of is to remove all unnecessary items from the data and to add items to the data when I want to add them to the tree view.
I wonder whether there is another solution without adding/removing items from/to the data?
You can filter the data source or hide some of the .k-item elements with jQuery.
I am using Kendo UI tree view with checkboxes. My problem is when i am loading the tree i will be checking some checkboxes using javascript. But this is not selecting parent checkbox automatically. Do i need to do this manually or is there any option in the framework.
Thanks,
Raja
Lets assume that you want to select the node that is selected:
// Get the node that is selected
var selected = treeview.select();
// Find the checkbox associated with this node
var checkbox = $("input[type='checkbox']", selected)[0];
// Click on it for selecting it and its ancestors
checkbox.click();
Being treeview the result of creating kendoTreeView:
var treeview = $("#my_tree").kendoTreeView({...}).data("kendoTreeView");
If you check the nodes by adding the 'checked' attribute with JavaScript
e.g.
$('input').attr('checked','checked')
you will need to handle the parent checking manually. However if you simulate click the TreeView will update its state as it would do if you have used the mouse to click.
e.g.
$('input').click();
Keep in mind you need to call the click on the checkbox input not the span element wrapping it.
Kendo ui (html5) treeview the position is reset to the begining of the tree.
when i bind the many records in the tree . when i select the last node the treeview position is reset to the begining of the tree.
This problem arises only in IE(Internet Explorer 9). in firefox and chrome it is working fine .
The image 1 shows the page that treeview reset to begining of the tree after selecting the tree node at the last record.
the image 2 shows the page that treeview node is selected at the botom
