Get uniquename of column to group it

[EBS]

I am attempting to create a client-side grid toolkit (export, print to pdf, group by column, expand/collapse all, reset grid).  All features wor except the group by column.  I can get the column index, but the groupcolumn clientside function requires the uniquename.  How can I get this?  The following code allows me to opposite-click on the grid and get the col index:

function ColumnContextMenu(sender, eventArgs)
        {
            alert(eventArgs.get_gridColumn().get_element().cellIndex);
            GroupByColumn(eventArgs.get_gridColumn().get_element().cellIndex);
            eventArgs.get_domEvent().cancelBubble = true;
        }

function GroupByColumn(cellindex)
        {
            var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
            masterTable.groupColumn("MyColumnName");
        }

Hi,

You can use get_uniqueName() method to achieve this:

alert(eventArgs.get_gridColumn().get_uniqueName());
