ClientNodeClicking + radconfirm

[Eng.Bassel Samman]

Dears,

I am using RadTree in my web page, I want to ask a user before moving from selected node to another
"Do you want to save changes?"  and give hime the following button options: Yes, No, and Cancel. Becuase javascript confirm has only Ok and cancel button, I used radconfirm and change the template as the following:

 

<ConfirmTemplate>

 

 

<div style="text-align: center">

 

{1}

 

<br />

 

 

<br />

 

 

<input id="btnYes" type="button" value="Yes" onclick="$find('{0}').close(true);" />

 

 

<input id="btnNo" type="button" value="No" onclick="$find('{0}').close(false);" />

 

 

<input id="btnCancel" type="button" value="Cancel" onclick="$find('{0}').close(null);" />

 

 

</div>

 

 

</ConfirmTemplate>

the radconfirm is ok, and it returns null when user click on "Cancel" button. but the problem is I have to call the radconfirm inside the treeview ClientNodeClicking event, and radconfirm has CallBackFunction, and in CallBackFunction I can not execute:

 

eventArgs.set_cancel(true);

becuase eventArgs is avilable only in ClientNodeClicking.
So, could you please help me in that.
