[CLOSED] TreePanel DirectEvent CheckChange

[ashton.lamont]

the checkchange event on a treepanel should have two parameters Node this, bool checked

<DirectEvents>
                        <CheckChange 
                            Url="~/UserService.asmx/SetActive" 
                            Type="Load"
                            Method="Post"                            
                            CleanRequest="true">
                            <ExtraParams>
                                <ext:Parameter Name="userid" Value="#{user_ID}.getValue()" Mode="Raw" />
                                <ext:Parameter Name="node" Value="this.id" Mode="Raw" />
                                <ext:Parameter Name="bchecked" Value="checked" Mode="Raw" />
                            </ExtraParams>
                        </CheckChange>
                    </DirectEvents>

When I evaluate the above the checked raw value is always correct but the this.id always returns the panel id and not the node id.

Any suggestions? This is not how I expected this to return based on ExtJS model.

i just figured it out.

You called it "node" and not "this". so it is "node.id". "this" is reserved for the container?

Is there some good documentation for these difference yet in ext.net?

Hi,

'this' in the Listener/DirectEvent is always references to the current control (control for which you added listener)
Please see ExtJS documentation to figure out what arguments are allowed for the event
For example, CheckChange

Vlad,

completely agree that the ExtJS manuals are necessary but we are looking at two different things in this case.

http://www.extjs.com/deploy/dev/docs...tree.TreePanel

checkchange
:
( <code>Node this</code>, <code>Boolean checked</code> )

<div class="short">Fires when a node with a
checkbox's checked property changes
Fires when a
node with a checkbox's checked property changes<strong style="font-weight: normal;">Listeners
will be called with the following arguments:[/b]<ul>[*]<code>this</code>
: Node<div class="sub-desc">This node[*]<code>checked</code>
: Boolean[/list]The ExtJS 3.2.1 docs on their site read that 'this' is the node. That is what I was trying to point out. So i kept trying to figure out why I couldn't get the right value from 'this'. And just happened to try 'node' but had no documentation to support trying that.

So this is where I am wondering am I looking at different documentation?

Thanks again,

[Vladimir]

Hi,

hmm... yes, online docs defines 'this' as node
But I think it is ExtJS documentation error ('this' for the CheckChange is tree)
