Actually,we have a node and i want that particular node not to drag from the tree to the grid.when user tries to drag that we need to give a alert message.is there any particular method for that???
Hello
Use the next:
tree.attachEvent("onBeforeDrag", function(sId){
if (sId=="specificID") {
dhtmlx.message(
{
text:"You can't move this node",
type:"alert"
});
return false
}
});
