Hi,

We use the release of 15-4-2008

This is the code we use. On the OnClientNodeEditedEventHandler we get the new text and offer it asynchronous to our database engine. When this call succeeds we set the text of the node with commit changes on.

function

OnClientNodeEditedEventHandler(sender, eventArgs)

{

var node = eventArgs.get_node();

var newValue = node.get_text();

var key = node.get_value();

var ctx = node;

ChangeObjectValue(key,

"Name" , newValue, eventArgs._node._originalText , myHelperID, onSuccess_ChangeObjectValue, onFailed_ChangeObjectValue, ctx);

}

function

onSuccess_ChangeObjectValue(serverResult, node, methodName)

{

if (serverResult.IsSuccessFul != true){

//terugzetten value

node.set_text(serverResult.Name);

}

else{

//servermodel bijwerken

var treeView = $find(RadTreeViewId);

var newText = node.get_text();

treeView.trackChanges();

//server should listen

node.set_text(newText);

treeView.commitChanges();

//server stops listening

var nodeKey = node.get_value();

processConnection(nodeKey);

}

displayMessage(serverResult.IsSuccessFul, serverResult.Message);

}

function

onFailed_ChangeObjectValue(ex, node, methodName)

{

displayMessage(

false,"Error");

}

Hello,

I managed to reproduce this error in the online demo site. De demo I use is Treeview -> Using Client-Side API -> Client-Side events. This are the steps:

Case 1

Select the node "Sent Items"
Go to edit mode with F2
Change node text in "Sent Items("
Exit edit mode by hit Enter
Select the node again
Node automatically goed in edit mode
Change node text in "Sent Items()"
Exit edit mode by hit Enter
Now you get the javascipt error: Expected ')' in regular expression
next javascript error
Node text not visible anymore

Case 2

Select the node "Inbox (14)"
Go to edit mode with F2
Change node text in "Inbox (14) aaaa"
Exit edit mode by hit Enter
Now the old node text is displayed

Case 3

Select the node "Sent Items"
Go to edit mode with F2
Change node text in "Sent Items()"
Exit edit mode by hit Enter
Select the node again
Node automatically goed in edit mode
Change node text in "Sent Items() aaa"
Now the node text changes in "Sent Items() aaa()"

Success!
