Treeview doesn't support javascript codes

[naveen veda]

hi,

i am using Radtreeview for asp.net ajax controls.

in java script,

node.get_checked() code gives error as  " Object doesn't support this property or method"

my code is,

function AfterCheck(node)

 

{

 

if (!node.Checked && node.Parent != null)

 

{

node.Parent.UnCheck();

}

 

 

var siblingCollection = (node.Parent != null) ? node.Parent.Nodes : node.TreeView.Nodes;

 

 

var allChecked = true;

 

 

for (var i=0; i < siblingCollection.length; i++)

 

{

 

if (!siblingCollection[i].Checked)

 

{

allChecked =

false;

 

 

break;

 

}

}

 

if (allChecked && node.Parent != null)

 

{

node.Parent.Check();

}

 

UpdateAllChildren(node.Nodes, node.Checked);

}

 

 

 

 

function

UpdateAllChildren(nodes, checked)

 

{

 

var i;

 

 

for (i=0; i<nodes.length; i++)

 

{

 

if (checked)

 

nodes[i].Check();

 

else

 

nodes[i].UnCheck();

 

 

if (nodes[i].Nodes.length > 0)

 

UpdateAllChildren(nodes[i].Nodes, checked);

}

}

previous version (Rad controls for Asp.Net)  the above code works fine,

can u give me the solution.

thanks,

Hi Naveen,

I guess you want all child Nodes of a Node are automatically Checked if their parent has been Checked and Unchecked if their parent has been Unchecked. If so you can try setting the CheckChildNodes property to True. You can find the important client side methods and events of RadTreeView for ASP.NET AJAX by going through following links.
