Expanding all NestedViewTemplates when grouped client-side

[Condorito]

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.

Any thoughts on this?   Thanks...

Yes, I too have a need for this functionality client-side.

Hello guys,

I suggest you try out the approach presented in the sample project from this code library thread. It should be applicable for NestedView templates, too.
