Link and Summation on a Column of TreeGrid

Can I set a column type as link that can do summation on a tree grid. Eg:grid.setColTypes(link[=sum]) .I want to be able to do summation on the cell contents with one of the cell type being a link.



Also can I do summation on specific parents of the tree grid instead of the entire column.





Can you help me with a code snippet if possible.

Not supported by default. You can try to use customized version of link excell , which can be taken from next tread.

You can set column type as link[=]
And specify in XML, formulas for necessary cells only
=sum
