treeview:how to get the selected node on javascript click event

[Naim Rizk]

hi,
I have a treeview with nodes that contain images of a checkbox. it can
be an image of a checked or unchecked checkbox. When a user click on a
node the image of the checkbox will change from checked to unchecked and
vice versa. And of course that will be done on the client side.

i added this javasript function.

function myfunction(){
SelectedNode =
event.srcElement.getTreeNode(event.treeNodeIndex);
if (SelectedNode.ImageUrl == "image1") {
SelectedNode.ImageUrl= "image2";
else
SelectedNode.ImageUrl= "image1";
}

anyway event.srcElement.getTreeNode(event.treeNodeIndex) is returning
null.

i just found that I can display a checkbox treeview by setting the
checkbox propety of the node to true. so my problem is solved. but
anyway if someone can tell we how we can get the selected node in
javascript and change the image,the text... i'll appreciate it

Hi,

try to use:
SelectedNode =
event.srcElement.getTreeNode(event.srcElement.clickedNodeIndex);

instead of:
SelectedNode = event.srcElement.getTreeNode(event.treeNodeIndex);
