Hello,
I use a RadGrid with a hierarchy system. I have 3 types of resources for my line (human, location, equipment) in my grid. But I only can  add a child if the resource type is a location.

I need to "disable or hide" the Expand/Hierarchy column, but I dont this attribute on the dataItem. 

How can I  "disable or hide" the Expand/Hierarchy column ONLY for "human and equipment" ?

Thank you :) 

 

I attach a files for explain what I have currently (left image) and the result that I hope to get (right)

Hi Mathieu,

To hide the expand/collapse columns, you can try the approach described in the hide group expand collapse columns in RadGrid forum thread.

If you only want to hide the expand buttons for specific items/or items that do not have children, you can try the following two approaches, one of which is the server-side approach described in the Hiding the expand/collapse images when no records article.  You can also implement this on client like the example below. 

<script type="text/javascript">
    function gridCreated(sender, args) {
        var dataItems = sender.get_masterTableView().get_dataItems(); // get the collection of grid rows (dataItems)
        for (var i = 0; i < dataItems.length; i++) { // loop throug the rows
            if (!hasDetailRows(dataItems[i])) // method to check whether the rows have detail tables that has any records
                $("#" + dataItems[i].get_id()).find(".rgExpand").hide(); // hide the expand button
        }
    }
    // method that takes grid row (dataItem) as parameter
    function hasDetailRows(dataItem) {
        for (var i = 0; i < dataItem.get_nestedViews().length; i++) { // loop through all detailTables inside the item
            if (dataItem.get_nestedViews()[i].get_dataItems().length > 0) { // check whether the detailTable has rows
                return true;
            }
        }
        return false;
    }
</script>
