Hi,

I have two treepanel with drag and drop enabled. I want to COPY a node from treepanel called 'TreeAllPrestation' to treepanel called 'TreePrestationBuilder' ONLY if a condition ocurrs.
The problem is that the node always is moved instead copyied and it`s dissapear from treepanel 'TreeAllPrestation'.

Why?Any ideas please?

Thanks a lot.

    

[AjaxMethod]

public bool TreePrestationBuilderBeforeNode(string id, string id2)

{

string targetNodeID = id;

int targetID = Convert.ToInt32(targetNodeID.Split(';')[1]);

int dropedID = Convert.ToInt32(id2);

IPrestation prestation = PrestationService.GetPrestation(dropedID);

if (prestation.PrestationType == PrestationType.Article)

{

Ext.Msg.Show(new MessageBox.Config

{

Title = "Icon Support",

Message = "You cann't bind articles",

Buttons = MessageBox.Button.OK,

Icon = MessageBox.Icon.WARNING,

});

return false;

}

return true;

}




function beforeDrop(dropEvent) {

Coolite.AjaxMethods.TreePrestationBuilderBeforeNode(dropEvent.target.id, dropEvent.dropNode.id, {

success: function(result) {

if (result) {

dropEvent.dropNode = new Ext.tree.TreeNode(dropEvent.dropNode.attributes);

}

return result;

}

});

}
