Hello!
I have master grid with stree column that contains items like this:
-item 1. openable, not selectable
–item 1.2 openable, not selectable
—item 1.2.1 selectable
—item 1.2.2 selectable
–item 1.3 openable, not selectable
—item 1.2.1 selectable
—item 1.2.2 selectable
I want to only specific nodes be selectable, so that double click on eg. item 1.2 only open the 1.2 but not select 1.2
Currently, when I click on item 1.2 my tree grid return item 1.2 value to master grid
I manage to block the selection by this code:
tree.attachEvent(“onClick”, function(rowId) {
if(!tree.getUserData(rowId,“selectable”)) {
tree.openItem(rowId);
alert(“You cannot select this node”);
}
});
But this also works on single click, and I don’t want that.
Behavior can be changed only by modification in dhtmlxgrid_excell_tree.js
dhtmlXGridObject.prototype.setSubTree=function(tree,s_index,t_index){
…
tree.setOnDblClickHandler(function(id){
that._sub_id = id;
that.editStop();
return true;
});
Can be changed as
dhtmlXGridObject.prototype.setSubTree=function(tree,s_index,t_index){
…
tree.setOnDblClickHandler(function(id){
if(!this.getUserData(id,“selectable”)) return true;
that._sub_id = id;
that.editStop();
return true;
});
