The above code works, except opening it this way does not fire the RowEditing_TemplateOpened event.

What I am doing is this, I have an "Edit" button in a templated column of my WebDataGrid.  I have set the OnClientClick event of that button to do the javascript to enterEditMode on the row.

I need it to fire the TemplateOpened event after that so I can position my Edit Template in the center of the screen.

I have tried putting the code to center it on the screen right after the enterEditMode but the problem is it does not work the first time I click on the Edit button, only the 2nd. 

            var grid = $find("<%=WebDataGraphics1.WdgGraphics.ClientID %>");
            var gridRows = grid.get_rows();
            var selectedRows = grid.get_behaviors().get_selection().get_selectedRows();
 
            var row = selectedRows.getItem(0);
 
            var rowEditingTemplate = grid.get_behaviors().get_editingCore().get_behaviors().get_rowEditingTemplate();
 
            rowEditingTemplate.set_dropDownEnableAutomaticPositioning(false);
            rowEditingTemplate.enterEditMode(row)
 
            var container = rowEditingTemplate.get_dropDownBehavior().get_targetContainer();
 
            var cntStyle = container.style;
            cntStyle.position = 'absolute';
            cntStyle.marginLeft = "0px";
            cntStyle.martinTop = "0px;";
 
            cntStyle.left = (document.documentElement.offsetWidth / 2 + document.body.scrollLeft);
            cntStyle.top = (document.documentElement.offsetHeight / 2 + document.body.scrollTop);

What version was this for?  I'm using 10.3 and I cannot get past the rowEditingTemplate.  I get an error when trying to do get_dropDownBehavior().

var rowEditingTemplate = grid.get_behaviors().get_editingCore().get_behaviors().get_rowEditingTemplate() ;

var container = rowEditingTemplate.get_dropDownBehavior().get_targetContainer();

and I get

'rowEditingTemplate.get_dropDownBehavior()' is null or not an object

Nevermind, I found my typo.
