Hi,

I have a Rad Grid with a NestedViewTemplate that can be expanded/collapsed client-side. One of the requirements for this grid is to also be able to expand/collapse all NestedViewTemplates in the Grid client-side with the event raised by an external control, which I can do easily with this code that I found here in an earlier thread:

    
            function expandCollapseAll(expand) { 
        
                            var grid = $find("<%=rgDomestic.ClientID %>"); 
        
                            var table = grid.get_masterTableView(); 
        
                            var rows = table.get_dataItems(); 
        
                            for (var i = 0; i < rows.length; i++) { 
        
                                var Row = rows[i]; 
        
                                if (expand == true) { 
        
                                    Row.set_expanded(true); 
        
                                } 
        
                                else { 
        
                                    Row.set_expanded(false); 
        
                                } 
        
                            } 
        
                        }

The problem is that I also have a requirement that the grid needs to have grouping-by-column ability (also done on the client-side). However, when the grid is grouped by a column or columns, the code above no longer works and gives me the following error message when it hits the line below, 'title' is null or not an object:

    
            if(_348.title==this._owner._hierarchySettings.ExpandTooltip)

Is there any way I can expand or collapse all nestedviewtemplates with an external control client-side when the Rad Grid has been grouped by a column? Thank you.
