Hi Lyuba,

Thank you for this sample.  It is very instructive even today.  I have modified it for 2011.v1 and it sort of works.  When I select add new, the template displays, but then it immediately dissapears and templateClosed is called.

<script type="text/javascript">

// flag used when the row edit template is closed to indicate if you should add new row

// set the flag to show that this is adding new

isAddingNew =

true;

//take the row editing template

var roweditingtemplate = grid.get_gridView().get_behaviors().getBehaviorByName("RowEditingTemplate"

);

//get the row adding behavior

function initializeGrid(sender, args) {

var grid = $find("<%=WebHierarchicalDataGrid1.ClientID %>");

var rowaddingbehavior = sender.get_behaviors().get_editingCore().get_behaviors().get_rowAdding();

// add onclick event for the selector cell of the "add new" row

$addHandler(rowaddingbehavior._rowElement.cells[0],

"click", showEditRowTemplateOnAddNew);

}

function templateClosed(sender, args) {

// if new row is added and the OK button is clicked

var grid = $find("WebHierarchicalDataGrid1");

var rows = grid.get_gridView().get_rows();

var rowaddingbehavior = grid.get_gridView().get_behaviors().get_editingCore().get_behaviors().get_rowAdding();

var rowValuesArr = constructArray(rowaddingbehavior._row);

rows.add(rowValuesArr);

}

//reset the flag awlays

isAddingNew =

false;

}

function constructArray(row) {

var arr = new Array();

for (var i = 0; i < row._cells.length; i++) {

arr[i] = row._cells[i].get_value();

}

return arr;

}

</

script>

Thank you very much, that does help!

I am having a second issue with the RowEditTemplate that I'll address in a fresh post.
