Hi,

Using webdatatree in 'ModalDialog' pop up, tried using

node._element.scrollIntoView(tree); - But it throws exception saying 'type mismatch'.

node._element.scrollIntoView(true); - does not scroll into the node selected.

Please suggest asap.

Hi Vasya,

Thanks for the reply.

I tried the below code in my client side.

function WebDataTree1InitializeTree(sender, eventArgs)
{
tree = sender;

if (tree.get_selectedNodes()[0] != null)

{
var node = sender.get_selectedNodes()[0];
var treeElement = sender.get_element();
sender._scrollToNode(node, treeElement);
}
}

This function is fine when the tree gets initialised for the first time.

But my requirement is that, on run time, i set the node using node.set_selected(true);, based on the search.

Inspite of the node getting selected, its doesnt scroll into view as this WebDataTree1InitializeTree does not get called everytime i set the node.

Can u please guide me on this.

Hello Jeevitha,

Thank you for posting in our community.

In order to scrollWebDataTree to the selected node what I can suggest is handling Initialize client side event. In this event you could scrollToNode function to scroll to any node of your choice. For example:

function WebDataTree1_Initialize(sender, eventArgs)

{

var tree = sender;

var nodesCount = sender.getNodes().get_length();

var node = sender.getNodes().getNode(nodesCount - 1);

var treeElement = sender.get_element();

sender._scrollToNode(node, treeElement);

}

Additionally, I noticed that the similar scenario has been discussed in the following forum thread that you might consider helpful:

I hope you find my information helpful.

Please let me know if you need any further assistance with this matter.
