Rootnode check with expandmode ServerSideCallback

[Gert Van Meerbergen]

Hi,

A root node is added to the treeview with expandmode ServerSideCallback. When clicked then server call is processed and child nodes are retrieved.

When the checked property on the root node is set to true, then no server call is triggered and loading image is shown. Do you need to preload child nodes of checked nodes or can't the checked be used with ServerSideCallback expandmode?

Hello Gert,

You are correct, when the checked status of the node is changed programmatically, no checked changed events are fired. 

What I can suggest is clicking the checkbox programmatically instead of changing the checked status. Here is a code that checks the selected node: 

var tree = $find("<%=RadTreeView1.ClientID%>");
var node = tree.get_selectedNode();
node.get_checkBoxElement().click(); //instead of node.set_checked(true)
