[Solved] Change text on Client Node populating

[Rizwan]

 

Hi
  I have a tree where I invoke LoadOnDemand event , My Requirement is to change the Node text to "Loading..." when ajax call is made and then back to orignal text when event completes.  Application works fine with Javascript on IE 8 however it does not work in IE7 where changing the text of node just make the node text blank and on completion set the old text back. This is the javascript

var oldtext;

 

 

var expanding = false;

 

 

function OnClientNodePopulating(sender, args)

 

{

 

if (expanding == false)

 

{

expanding =

true;

 

oldtext = args.get_node().get_text();

// This line works in IE8 but in IE7 it does run smoothly wihtout any change of text in node
args.get_node().set_text(

"Loading...");

 

}

 

else

 

{

args.set_cancel(

true);

 

}

}

 

function OnClientNodePopulated(sender, args)

 

{

args.get_node().set_text(oldtext);

expanding =

false;

 

}

This is the tree definition

 

 

<telerik:RadTreeView runat="server" ID="tvBrowse" OnNodeExpand="tvBrowse_OnTreeNodePopulate" Height="100%" Width="100%" TriStateCheckBoxes="true" CheckChildNodes="true" CssClass="treeclass" CheckBoxes="true" onclientnodepopulated="OnClientNodePopulated"

 

 

onclientnodepopulating="OnClientNodePopulating">

 

 

 

 

 

 

</telerik:RadTreeView>

 

 

 

Waiting for your adivce.

Best Regards

Hi Rizwan,

I've tested this in IE7 and it worked without a problem. I've attached my test page for a reference.

Kind regards,
