Hello,

Yes it is possible. Perhaps you could use GetChildRows() method to know whether the row have a child table or not.

Here’s the snippet example code how to use GetChildRows() method:

<script language="javascript" type="text/javascript">
    function expandChildRow() {
        var grid = ISGetObject("WebGrid1");
        var selObj = grid.GetSelectedObject();
            
        if (selObj == null) {
            alert("Please select a row");
            return;
        }
        else {
            var row = selObj.GetRowObject();
            if (!row.ChildExpanded) {
                    //Expand the child row                   
                    row.ExpandChildRow(true);
                    //Get child rows
                    var childRows = row.GetChildRows();
                        
                    //If the row have child rows
                    if (childRows)
                        alert("This row have child rows!");
                    //If the row doesn't have child rows
                    else
                        alert("This row doesn't have any child rows!");
            }
            else
                alert("Row already expanded!");
        }
    }
</script>

Hope this helps.

 

Thank you.

Hans.
