client-side .check() not working

[Stephen Arnold]

I have 2 treeviews and when I check something in one I need something to be checked in the other. The one that has the event is working and calling my checkNode(text) function. The checkNode function is executing everything correctly, except when it calls the node.check() nothing is happening. I made sure it is finding the node and has the right object, it is just not checking it. Code is below:


function

 

onNodeChecked(sender, args) {

 

 

var node = args.get_node();

 

 

if (node.get_checked()) {

 

 

if (node.get_text() == "Region") {

 

checkNode(

"Region");

 

checkNode(

"State");

 

}

}

}

 

function checkNode(text) {

 

 

var tree = $find("<%= ColumnTreeView.ClientID %>");

 

 

var node = tree.findNodeByText(text);

 

 

var nodetest = tree.findNodeByText("Region");

 

nodetest.check();

 

var nodes = tree.get_allNodes();

 

 

if (node != null) {

 

alert(

"checking something");

 

node.check();

}

}

Hello Stephen,

Your code works fine in my end. Give a try with set_checked(true) method in order to check the item. Do you have any other settings which cancels the checkbox checking.

Could you provide complete code that you tried if this does not help?

Here is the whole ascx. It is a user control not sure if that is part of the problem.
